Canon EOS-1D X filmmaker’s DSLR

HD DSLRs have been hugely popular, partly because of their low cost, but also because of the creative possibilities of the large sensor and shallow depth of field. Now Canon has announced its next generation DSLR, the EOS-1D X, which is positioned as "the film-maker’s DSLR" and addresses most of the main problems video users have with its 5D Mark II and 7D cameras.

It will allow users to record full HD movies from its full-frame 24x36mm CMOS sensor with a full range of manual settings to control exposure, focus and frame rate - 1920x1080 at 30 (29.97), 25 and 24 (23.976) frames per second, or 1280x720 at 60 (59.94) and 50fps, plus SD video in PAL or NTSC.

Sound levels can be displayed on the 3.2-inch 1.04million-dot LCD screen and adjusted during a take. It also has SMPTE Timecode (Rec. Run and Free Run), so you can synch it with other cameras or audio recorders.

It will use a new H.264-based intra frame (ALL-i) video codec to maintain higher video quality (and to be more edit friendly), limiting compression to retain more information for post-production – although it appears that it is still 8-bit video (.MOV files). Canon hasn't yet revealed what bitrate it will use, but anything less than the 50Mbps required by most broadcasters for HD (and offered by Canon's XF range of video cameras) would be a disappointment (and the only, unconfirmed, report there is about the bit rate is that it will record six minutes on a 16GB card, which is about 44Mbps). There is also an interframe IPB long-GoP compression option.

Dual Digic 5+ processors

It has dual Digic 5+ processors that work to reduce moiré artefacts, rolling shutter effects and chromatic aberration. There is no line skipping, which will also help deliver a cleaner picture. The new Digic 5+ processor is 17x faster than the Digic 4.

The camera also offers longer recording, automatically creating a new file once the 4GB file limit has been reached, which allows it to record for up to almost 30 minutes at a time (up from about 12 minutes before the 4GB limit kicked in). The new 29 minutes 59 seconds limit is due to EU levies on video recorders, which would result in about a 30% price increase if it recorded for 30 minutes or longer. It has two Compact Flash card slots for recording.

The sensor has much improved light gathering capabilities and wider dynamic range (the individual pixels are 0.55 microns larger than those on the 5DMkII's sensor, with gapless microlenses for enhanced light gathering efficiency, higher sensitivity and less noise at the pixel level). 

The ISO range for movie shooting now runs from ISO 100 to 51,200 (for stills it can be expanded to go from 50 to 204,800). In the sample EOS-1D X movie on the Canon website, the video was recorded at ISOs up to 25,600 with no appreciable noise – at least not viewable at the resolution the video is shown at.

There is also a dedicated Digic 4 processor for the metering system, which also handles face detection and colour to ensure correct exposure levels and improved auto-focus tracking, using a redesigned 61-point focusing system.

It has a Gigabit Ethernet port (above - top right), which could mean it can download video remotely and enhance its remote control capabilities, but exact details of what this might enable for video weren't revealed.

The EOS-1D X is also Canon's top-end stills camera, replacing both the 1Ds Mark III and 1D Mark 4, and shooting 18.1-megapixel images at up to 14 frames per second. It will cost about $6,800/£5,299/6,299 when it ships at the end of April [UPDATE - now expected mid June 2012].

EOS milestone

Canon produced its 50-millionth EOS-series SLR camera in September (having made 10 million EOS cameras in just 16 months), and expects to have manufactured 70 million of its EF lenses by the end of October (producing 10 million in a mere nine months) – it started manufacturing both ranges of cameras and lenses in 1987.

Gekko lenslite DSLR mount

Gekko Technology will introduce a new DSLR mount for its established lenslite at IBC. The mount will allow direct attachment of the colour-stable, robust ringlight to Canon 5D, 7D and Nikon D3 cameras.

It will fix directly to the base of the camera via the tripod screw and secures 15mm bars that hold the lamp head on axis around the lens. The base of the mount has an additional fixing so the camera/lenslite combination can still be mounted on a tripod, but with the centre of gravity moved forward for stability.

“DSLR cameras such as the Canon 5D have become very popular tools for video content acquisition and look likely to remain so given their versatility,” commented Gekko founder and MD, David Amphlett. “The new lenslite DSLR mount provides all the benefits of a high-quality solid-state fixture that was once only the domain of much larger professional cameras."

Designed for studio or location production, and with a colour temperature of 5600K, lenslite delivers 260 foot candles of intensity at a distance of 1m. It can be used as a primary light source or as soft fill, and powered by any 12-volt to 40v power source. Accessories include filter stages, gel holder, gel cutting template, adjustable French flag, wireless or cabled dimmers and a remote DMX interface.

Atomos Ninja Review

The Ninja, by Hong Kong/Australian company Atomos, is one of a growing group of on-camera recorders. These devices enable you to bypass the camera’s compression and record at a higher bitrate on those cameras that have non-compressed HDMI outputs (in the Ninja's case) or HD-SDI. [UPDATE: Atomos now has HD-SDI to HDMI and HDMI to HD-SDI Connect convertors that make it easy to add HD-SDI inputs to Ninja] [UPDATE 2: The Ninja 2 has been launched - better display, HDMI output, compatible with new AtomOS 3.0 firmware]


After a couple of delays due to software problems, the Ninja is now shipping and will be joined eventually by the Samurai, which will record using HD-SDI and have a larger, higher-resolution screen.

The Ninja comes in a handy hard carry case. The kit includes two hot-swappable hard drive caddies, two batteries with a dual charger and a docking station for the drive with FireWire 800, USB 2.0 and 3.0 and eSata connections.


PROBLEM 1 

All of these field recorders have three problems they are trying to solve.

First of all: image quality. For example the new Canon XF305 records 50Mbps 4:2:2 while Sony's EX1 and EX3 record 35Mbps 4:2:0 onto their solid-state memory cards. But, they are more than capable of exporting pictures of higher quality via their HD-SDI and/or HDMI sockets (the EX3 doesn't have HDMI, but the newer EX1R does). Field recorders allow you to tap into those higher quality images.

The Ninja records 10-bit ProRes HQ at 220Mbps, ProRes 422 at 150Mbps or ProRes LT at 100Mbps in hardware, and Apple has checked that it is "bit-for-bit accurate" (and gave its approval) according to Atomos CEO, Jeromy Young.

Most DSLR cameras record in H.264, a great codec for a video project ready for upload to the web, but not much fun to edit with. A separate recorder using a more edit friendly codec should make your editor happy and mean less time hanging around waiting for video to render or be transcoded.

PROBLEM 2


Storage capacity. A 32Gb Compact Flash card will hold around 40mins of video at 50Mbps. Most professional cameras can hold two cards, but if you need to shoot a lot of video you will have to keep swapping cards throughout the day. Plus, you typically only have one copy, which can be worrying, especially if you are new to tapeless recording.

With the Ninja you record to a 2.5-inch 9.5mm-high laptop-sized hard drive – disk or solid state. These are not included in the kit but they are readily available. A 500GB drive will give you around five hours of recording time in ProResHQ, 7.5 hours in ProRes422 and 11 hours in ProResLT. Now you can shoot all day and/or have two copies, just in case.

Atomos recommend fast (7200rpm) hard disks rather than 5400rpm ones. If the disk is knocked during recording you may see the Skippy icon – a kangaroo in a yellow diamond – to let you know there is a problem.

If your shoot involves a fair bit of rough and tumble, you should consider buying the more expensive solid-state drives (SSD). At the moment Atomos only recommends Intel SSDs, but new drives come out all the time so it is a good idea to check its checked and approved list.

The drives fit inside the supplied master caddy for protection. If you buy extra drives you way want to buy an extra pack of five caddies for around £25.

During my test of the Ninja I plugged it into a Canon XF105. With its infrared function I wanted to leave it recording the wildlife in my garden all night. With a large battery on the camera and two large batteries on the Ninja, I managed to record for up to ten continuous hours. When I looked at the drive the video had been chopped into 4GB sized files (around 4min 35sec in ProRes 422).

PROBLEM 3 

Power management: Having 11 hours of recording time is no use if the batteries can’t keep up. The Ninja has a dual battery system, using common Sony DV batteries. The two NP-F570 batteries in the kit offer around 4.5 hours of power. But, these are hot swappable, so when one depletes, it will switch to the second, and the first can be replaced. So, if you intend doing a long continuous shoot you shouldn’t have any problems. I have some spare Sony NP-F970 batteries, which still had plenty of juice to spare after being on for ten hours.

Ninja dual battery system

At the moment the Ninja only shows battery voltage remaining – not time remaining. This will be upgraded in a forthcoming firmware upgrade.

GETTING ATTACHED 

The Ninja with both batteries and drive weighs in at 700g. It has standard 1/4-inch mounts on the top and base of the unit. You may want to buy a variety of 1/4-inch screw-to-cold shoe connectors – especially if they have a ball and socket joint to easily position the Ninja on the camera. I used a small articulating arm to mount the Ninja to my Canon XF305. Which allows you to position the unit exactly where you want it.

An articulating arm to help position the Ninja

You’ll also need an HDMI cable to connect the Ninja to the camera (it's not included in the package). There really is no need to spend a huge amount on expensive gold cables. If the digits go in and come out of the cable you’re fine. That said cheap cables may be OK round the back of the TV, but, might not survive the rough and tumble of being on the road. If the cable falls out during recording you will get the Skippy icon warning. If you are of a nervous disposition you might want to splash out on a locking HDMI cable.

The Ninja comes with a touch sensitive screen/monitor – so it could be used by a director as a video assist or perhaps by the sound recordist to check for a boom in shot.

DSLR users may find the Ninja monitor helpful when doing very low angle shots – when a typical DSLR screen is almost impossible to see unless you lie down on the ground.

The Hague CamFrame

The monitor is there just for a confidence check that you are getting an image and composition is OK. It is not something I would use to help me with focus. But, if they add peaking in a future firmware upgrade DSLR users will find it more useful.

At the moment playback on the monitor is very blocky and stutters. But, Atomos already has that on its to-do list in a future firmware upgrade.

USER INTERFACE

The Ninja interface is easy to master. So, if you don’t like reading manuals you’ll be OK. That said the manual is well written, with plenty of photos to guide you through the set up process.

Ninja Main screen

All the controls are via the touch screen monitor. When you switch on, four round buttons appear on screen - REC (record), PLAY, MON (monitor) and MENU.

Along the top of the screen the Ninja indicates whether there is No Input and once you plug into your camera what resolution and frame/field rate it is receiving.

Next to that it tells you which ProRes codec is chosen for recording. To change it just tap on the screen and it will cycle through the options. In the top righthand side of the screen you can see which battery is being used. If you tap on this you can find out how much battery voltage each battery has left.

In the bottom righthand side of the screen you get an indication of recording time. Tap on this and you’ll get information on the make and model of the drive, its size and an option to format it. Formating will prepare the disk for recording the first time it is used – but it will also delete everything on the disk too.

Drive info screen

I tested the Ninja with several cameras. Using it with the Canon XF305 and XF105 was very simple. Both cameras have a cold shoe mount and a 1/4-inch screw mount – so you can use either way to mount the Ninja. The shortest HDMI cable I had was 2m – which was too long, half that length would have been fine.

We also tried it with our small Panasonic TM700 1080 50p (or 60p US) camcorder, which normally records at up to 28Mbps AVCHD. This non-standard AVCHD format isn't easily editable by Final Cut Pro, so being able to capture it in ProRes should make it much more practical. However, it doesn't seem that the Ninja can capture 50p, instead recording it at 50i (although the pictures are an improvement).

DSLR 

Atomos will have to disappoint Canon HD DSLR users who were hoping to be able to record perfect uncompressed video via their HDMI ports. The video should still be uncompressed (so long as you don't also record in camera at the same time on some models), but it won't be perfect, as it seems that Canon has helpfully included a white square or a red (recording) dot on a corner of the output, which will be noticeable if you try to use it as full HD.

Canon EOS 7D HDMI output with red dot in the corner of the picture

Atomos has asked Canon about this, but it seems that the spoiler may be deliberate to maintain the distinction within Canon between the photographic and video divisions. 


Canon EOS 7D HDMI output with white "zoom tool" box in the corner of the picture

Atomos hadn't detected it when they tested a Canon 7D initially as they shot some footage in a studio with a white background. It was only during beta testing that users spotted it, and further testing revealed the white square on the 7D and the red spot on other models.

However, some DSLRs apparently have HDMI output that is pristine (the Sony Alpha models and Panasonic's GH2 have been reported as working, although we don't have them so can't check). The Ninja also works perfectly with any video cameras they've tested it with, such as the Panasonic AF101 and Sony's F3.

WELL CONNECTED

It has LANC input/output for control (as well as the 4.3-inch touch screen). For audio, it has a mini-jack stereo input, or can record up to six channels of digital audio via HDMI (if the camera supports it), and a headphone jack.

Ninja connections - HDMI, LANC and audio
Atomos are committed to upgrading the firmware on a regular basis. So, features will be improved and added in the coming months.

Menu screen

If you press on the Ninja's menu button and then the Ninja Info button you can check which firmware version is currently running on your unit. The Ninja we recieved for review was on version 1.02. On the firmware download page they were up to version 1.04 so I thought I'd have a go.The first thing to do is download the zip file from the download page.

Then go to the instruction page and follow the instructions precisely.

The two important things to remember are to format the drive, using the Ninja, before you start and attach fresh batteries to the Ninja so that you don't lose power during the upgrade.

Once the drive was formatted I placed it in the master caddy and copied the firmware file over, which took a few seconds.

copy the firmware file to the formatted drive

Then I placed the drive in the Ninja and switched it on. There were coloured bands flashing at the top and bottom of the screen for about and minute (to prove it was doing something) and then it switched itself off.

Version 1.04 successfully upgraded

When I switched back on and checked the firmware was the new version 1.04. All very simple and exactly as outlined on the Atomos website.

EXPORT TO TIMELINE

Once you’ve finished recording, you place the drive in the master caddy into the docking station, which can be powered via the mains or by the FireWire connection.

Firewire and USB 2.0 and 3.0 on docking station

If time is short you can edit straight off the drive. In fact if a whole shoot fits on one drive it could be the editing drive and archive all in one…at least in the short term.

But, us nervous types will be backing up all that data. This is all very simple just connect the Ninja drive and drag and drop the ProRes files onto the drive you usually edit from and away you go.

ATOMOS NINJA - PROS:

  • Good value: It costs €795, £695 or $995
  • Well built and should be robust, especially with solid-state drive
  • ProRes is wonderful to edit (not just for Final Cut Pro users, as other non-linear editors can use it too, even on Windows with a plug-in) – you can even plug in and edit from the drive
  • Higher quality video, which might not be easily evident when you just compare the two side by side, but will be once you do anything to the video, especially for something like colour correction, where having the 10-bit 4:2:2 images will allow you do much more subtle colour grading
  • Small – it makes the AJA Ki Pro Mini look like the Ki Pro Maxi
  • Easy to use interface


ATOMOS NINJA - CONS:

  • Uses HDMI, which isn't usually a locking connection
  • No HDMI pass through (so you can't plug it in to a better monitor)
  • No HD-SDI connection (which is coming in the Samurai)
  • Low-resolution monitor (480x270 – compared to 5-inch and 800x400 on the Samurai)
  • Limited playback capability – although this will be improved in future, it's a much lower frame rate than normal (not helped by the low resolution)
  • No XLR audio inputs (unlike some of its, admittedly more expensive competitors)





IN CONCLUSION 

The Ninja is a well built and easy to use device. It has evolved since we first saw it at IBC2010 and Atomos has obviously listened to feedback from potential customers. If you have a Pro camera with HD-SDI you may want to wait for the Samurai. But if your camera has HDMI output this is a cost effective way to back up your video on the fly at a higher quality than your removable flash media.

If you are a DSLR owner you need to check whether your camera will work with the Ninja… or hope Canon relents and issues a firmware upgrade to remove unnecessary on-screen icons.

So, is it worth buying? Certainly, if you have something like a Panasonic AF100/AF101 (although it will only output 8-bit video), any of the Sony 35Mbps XDCAM EX range (including the PWM-F3), or the little Panasonic HCK10 point-of-view camera, all of which have been approved for HD use by the BBC, but only when they are recording to an external recorder at 50Mbps or above. It is currently the least expensive such recorder on the market, and it works well – although there are still some things to iron out.

In the medium term: There will soon be a lot more recorders for you to choose from. The newly announced Blackmagic Design HyperDeck Shuttle (see our review of the Shuttle) will only cost $345 and will record uncompressed video. If you want the best for less, this is it – however, big caveat: uncompressed images are huge. If you are recording for any length of time, you'll need lots of big, expensive, SSDs. It is a great option for certain types of work where you want the maximum quality and don't need long recording times, but if you want a compressed system, to save space and allow you to edit the pictures as quickly as possible, ProRes is a great choice.

Being able to do real-time ProRes compression in the recorder is where a lot of the extra cost of the Ninja goes. The real choice for many then will be between the Ninja and the Samurai (which could ship sometime over the Summer or maybe in the early Autumn). At £929, €1,095 or $1,495, the Samurai is still very good value (about 50% less than the admittedly excellent AJA Ki Pro Mini, with its XLR inputs, both SDI and HDMI, and Compact Flash card recording).

If you have an HDMI camera, you should certainly shortlist the Ninja. If your camera only has SDI, then the Samurai would be your value choice. If you need to do both, then look to: AJA; Fast Forward Video's $2,495/£1,695 sideKick HD recorder/monitor which also records ProRes to SSDs; or the upcoming sub-$3,000 Sound Devices PIX 240 recorder, which can also record using the Avid DNxHD video format (there will also be a PIX 220 that is HDMI only and expected to be under $2,000). And if you want even higher quality recording, then the more expensive Gemini 4:4:4 (under $6,000) from Convergent Designs will be the one to watch. However, except for the Ninja, the Ki Pro Mini, and Convergent Designs' industry-standard 8-bit nanoFlash, none of those are shipping yet.

[UPDATE: Other reviews are creeping out. Here's one by LA filmmaker, James Boyd.]

[[UPDATE: Atomos has introduced new Samurai Blade with a sharper monitor and upgraded operating system (AtomOS5) – it has also cut the price of both the Samurai and Ninja-2]]

Canon updates EOS Final Cut Plug-in

Canon is showing the latest update for its EOS Movie Plug-in-E1 for Apple’s Final Cut Pro at NAB. The software provides quicker and easier editing of EOS Movie footage for FCP users.

The new version (1.2) will make importing EOS Movie files easier, allowing users to transfer files from any folder, without needing to mirror the folder structure on the camera itself.

It also enables smoother importing from Canon’s EOS 7D, EOS 5D Mark II and EOS-1D Mark IV models, allowing users to import footage without requiring the THM file generated by the camera.

The plug-in is designed to seamlessly convert EOS Movie footage into Apple’s high-quality ProRes 422 codec about twice fast as Apple’s standard conversion.

EOS Movie Plug-in-E1 for Final Cut Pro version 1.2 will be available to download free from 25th April 2011.

DSLR v Video: Why not both?

A matter of choice: Gollner and Davis (and Canon 550D DSLR)

HD DSLRs are now widely used for video production, even for prominent TV series and movie making. Users love the shallow depth of field and low cost of entry. But just how useful are they for professional production, how do they compare to low-end video cameras, and can they withstand the introduction of large sensor video cameras that give the same look but without the operational problems?

"The tones of the images, the look, the range of lenses, the animation capability – they make these cameras a dream for independent filmmakers, but they're not good for everything. For the videographer who gets paid to shoot, run around, be quick, gather audio, videos, interviews. Quick turnaround. Guaranteed results, meaning its not going to screw up; the DSLRs have proved far from ideal," said Rick Young, editor/director/cameraman, MacVideo.TV.

For him it's not a matter of choosing one over the other, "they're both fantastic," but of choosing the right one for a particular shoot.

Producer/director, Matt Davis, MDMA, has a Sony EX1, and wanted to do wider shots. So, he bought expensive wide-angle adapters, but then worked out that a Canon 550D costs less than the adapter, even including the wide angle lens (he bought a Tokina 11-17mm zoom, which he praises for its sharpness). "The wide angle experience has been absolutely monumental. It does everything that an EX1 can't. There is no droop at the sides. It's got this wonderful panoramic feel. It is a smaller camera that can get into smaller places." He is only now investing in longer lenses.

"It had to work with an EX1. It couldn't just stand on its own looking beautiful and arty. It had to play fair with the rest of the video family." He makes sure that both the DSLR and the EX1 are shooting within similar contrast ranges "It's close, but it's not exact. It still needs a little bit of finishing off in Final Cut," to match the two pictures, but that is now quick and straightforward.

When he cuts the two together, it is difficult to spot the difference. The blacks can give the DSLR footage away. The EX1 can use Cine Gamma to give soft ramping in the blacks, and the DSLRs don't necessarily have that exposure range. "They're pretty and they're good, but they have limits, and you really can't push beyond those limits like you can with a decent broadcast camera," said Davis.

"If you look at DSLRs in isolation they look fantastic," said Young. "But when you put it together [with video], that's when you can really see the difference."

Young has augmented his two Sony EX1Rs and two JVC HM100s with two Canon 5D Mark IIs with Canon 16-35mm and Sigma 12-24mm lenses, "and it's staggering what you can get out of it. And even if I only use the DSLR for nothing but those wide shots, it would suit a fantastic purpose. The cost of buying a serious wide-angle lens for conventional video technology would be more than probably buying the whole DSLR package," he told the recent MacVideo Expo in London.

"We need this technology. It doesn't mean that it is everything; it complements what we've got, but it doesn't necessarily take over," although it has become "an integral part" of the kit he needs.

RAW deal: Young in a still from a demo sequence

Overcoming limitations

"It's just another tool, and it's a very exciting tool," said Den Lennie, founder, F.Stop Academy, who shoots with a wide range of cameras from Digital Betacam to XDCAM EX and DSLRs. He has produced four training DVDs dealing with HD DSLRs, but they have not all been shot using DSLRs. The 5D Mark II training videos were shot on a Sony XDCAM 350, while the Canon 7D DVD was shot on an EX1 and 5D Mark II.

"The limitations of DSLRs particularly lie in the audio," and when he was shooting in Malaysia with Dan Chung it was essentially a two hour documentary, which would have been much more difficult to do if he had to use a separate audio recorder (see some clips from it at www.dslrvideoonassignment.com). However, the training video uses both EX1 and DSLR footage cut together, which works very well. "You really don't have to do a lot of work [in post] if you match your cameras up beforehand," he added.

He tends to roll the sharpness, contrast and saturation down on the 5D Mark II, and bring a little back in post if necessary, and also roll down the detail settings on the EX1. The fundamentals of the craft of filmmaking remain the same whichever you use.

Alex Gollner, producer/director/editor, Alex4D.com (who has created a wide range of free Final Cut plug ins), now uses a Canon EOS 7D and 5D Mark II as his primary cameras, only occasionally using video cameras.

He likes to use a DSLR because he so often has to interview people in small rooms where the background would be distracting if he didn't have shallow depth of field. It also allows him use a very small lighting kit, enabling him to set up more quickly. He doesn't do news style material with it, where he would choose his HDV camcorders.

DSLRs give "blurred backgrounds behind my interviewee" and a "touch of class" to the result, he feels.

He uses a Zoom H4n recorder for audio and gets his subject to clap. "Synching only takes a few moments, as long as I don't stop and start the camera too often, and make sure they answer in less than 12 minutes," due to the file length restrictions.

He generally uses the camera locked off and just zooms in in post for close ups, as 720p is what most clients want the video delivered in.

When shooting on the EX1, Lennie uses a Tiffen low contrast filter to help smooth out some of the contrast so it matches better with the DSLR. "It is much easier to shoot on video where it's necessary to shoot in difficult conditions or where you are working as a one man band rather than using the Zoom recorder." If he has to synch DSLR audio in post, he uses PluralEyes (www.singularsoftware.com).

He filmed a concert recently for The Skids on five 7Ds, where the 12 minute recording limit was an issue (similar to shooting on film), so they staggered the recording on each camera by about 30 seconds and stopped/started recording one by one at the end of each track, for a two hour shoot. "You make a decision on what's right for the project," he said.

Davis feels that there is space for both proper video cameras and DSLRs at the moment, until the large sensor video cameras establish themselves. "I definitely do need both because there is no such thing as a single perfect camera." He finds that people react differently to stills and video cameras. Sometimes, if they see a DSLR, they may pose as if for stills, so you can get less posed reaction shots with a video camera.

Lennie doesn't worry about rolling shutter effects, as it's not an issue for most of what he shoots, while problems with moiré can be countered by using filters or defocusing. "It's just a limitation of the technology." He feels that DSLRs are particularly good for shooting in the back of a cab or other confined space.

Even with the Panasonic AF101 and Sony F3 coming along, Young feels that DSLRs still have some advantages, such as their compact size. He finds all of his cameras equally useful and they are used for different things.

Reflecting on glass

One problem, said Davis, is that a 50mm lens is not really a 50mm lens on cameras that use APS-C (which has a 1.5x or 1.6x crop factor) or Micro Four Thirds (2x) sensors. "The standard lens on a full frame camera is quite a long telephoto on a Four Thirds camera."

However, he feels that investing in glass will hold its value. "Glass can be a long term investment. The back end doesn't matter. Think about the front end."

"My clients are not going to see too much of a distinction in between video quality" on these cameras, said Gollner. It's more his own pride that makes the difference.

"If the client's images look better and they are paying less or the same for a higher quality product, that makes you look good," added Lennie.

Gollner believes that he could possibly achieve the same with DV or HDV, but it would take some extra work. "I'm just getting better quality pictures for a little less work than I used to a few years ago."

"It's all about the pictures […] who cares about what the camera is," added Lennie, "It doesn't really matter what you shoot on if you know how to shoot well."

"For extreme wides and extreme beauty shots," DSLRs "can't be beat," concluded Young, but for most other things, especially long record times and having all the right controls in the right place, he turns to his video cameras.

PL-mount Cine-Xenar primes primed

Chrosziel is to sell the new Cine-Xenar lenses from Schneider-Kreuznach worldwide, and has developed a complete set of accessories for them.

It has put together a package that includes: the five prime PL-mount lenses (25mm/T2.2, 35mm/T2.1, and 50, 75 and 95mm T.20 versions), plus its LightWeight Support; MatteBox 456 Academy Double; Bellows with Light Prevention Tube; DSW Direct Swing-Away-System; Studio Rig Cine Single follow focus; and a transport-trolley case.

The package will cost €18,450 (compared to €21,375 for the individual items), and the case will also be able to take the upcoming 18mm T1.9 Cine-Xenar lens. There is also a version for the Canon EOS 7D HD DSLR, costing €18,560 – as it needs extra lens support to relieve pressure on the EF-S mount. Once properly aligned, the MatteBox and Follow Focus remain unchanged when switching lenses.

The Cine-Xenar lenses are claimed to offer "excellent picture quality" and use a telecentric design, which ensures even illumination across the entire sensor.  The lenses have 12, 14 or even 18 iris blades, for a "unique bokeh". All the features are "remarkable for this price,” claimed Chrosziel. Additional sets for Red cameras and the Arri Alexa were shown by Chrosziel at Cinec in Munich. For more information, there is a pdf datasheet to download.

Beating budget bugbears and bitrates

There is a lot of really great technology being used on budget cameras – unfortunately, not all on the same camera…

Whether you are using an HD DSLR or any of the many compact camcorders, it is possible to produce very nice looking pictures. It isn’t easy and broadcasters might flinch from the results because some aspect of your camera doesn't meet their technical requirements for HD. However, the distance between the camera you have and the camera you need seems bridgeable. So, why isn't it being bridged?

At the HD Masters 2008 conference, Andy Quested, principal technologist, BBC HD, stated that he essentially wanted a camcorder with the front end of a Sony EX1 and the back-end of a Panasonic HVX 200 (or similar), as the BBC didn't believe that compact cameras with sensors of less than half an inch or inter-frame camera compression below 50Mbps were good enough for HD. Given that as the BBC goes, many others would follow, you'd think manufacturers would have rushed to produce something with exactly those specifications.

After all, there are an awful lot of Sony Z1 HDV camcorders out there (which were used to shoot observational documentaries and more in standard definition), and production companies are crying out for an HD replacement.

For that market, size is critical, as is ease of use. Price is also an issue, but less critical than you might think if the technology is right. However, manufacturers would prefer that broadcast users would buy their larger, more expensive models, which are not what productions need.

At the moment, the closest to the ideal seems to be the new Canon XF300 and XF305 camcorders, which are the most affordable cameras on the BBC's latest list of approved cameras for HD production – although they are only permitted for use by independent productions. The XF300 costs less than £6,000, while the XF305 (pictured) adds HD-SDI output, Genlock input and Time code i/o for about 10% extra. The other cameras on the approved list cost at least three or four times more.

The XF models are Canon's first Full HD MPEG-2 4:2:2 50Mbps camcorders (meeting one of Quested's parameters). They record MXF files to Compact Flash cards, and are highly compatible with broadcast post production. Most rival cameras record 4:2:0.

However, behind their 18x L-series HD lenses, the cameras have three 1/3-inch CMOS sensors. Although they are claimed to offer "exceptional colour accuracy, wide dynamic range and low noise" and use high-speed data readout (2x speed) to minimise the rolling shutter skew common to most CMOS camcorders, the sensor size isn't ideal.

The cameras also offer slow and fast motion recording, with 20 speeds to choose from in 720p mode and nine in 1080p (normal recording speeds are 1080 50i or 25p, 720 50/25p (in the European versions). The upcoming Canon XF100 and XF105 use the same recording system, but have only one CMOS sensor, which will inevitably diminish picture quality - even if that won't be evident to many viewers. However, their size seems perfect for typical self shooters.

Sensor sensibility

What many productions would like are larger sensors. Much larger. Conventional broadcast cameras tend to use three 2/3-inch sensors, but HD DSLRs usually use a single APS-C sensor (some 5.5 times larger and roughly the size of a 35mm movie frame). This gives very shallow depth of field and permits the use of a wide range of excellent lenses that are often relatively inexpensive (by video standards). Some DSLRs, such as the Canon EOS 7D, can also be fitted with PL-mount cine lenses.

The results can be excellent. However, there are lots of compromises to be made. The latest slew of HD DSLRs from Sony, Nikon and Canon suffer from a range of "features" that can frustrate anyone trying to use them for serious video production.

The recording bitrate on HD DLSRs and budget camcorders is almost invariably too low. The Canon 550D/60D/7D trio are about the best of the bunch, recording at 44Mbps, but Sony's DSLRs record using the more efficient AVCHD, but at just 17Mbps (despite the fact that the AVCHD standard goes up to 24Mbps). Nikon hasn't revealed official figures for its new D3100, but our testing showed about 20Mbps on a pre-production model. At the very least both should have aimed for 24Mbps.

Panasonic's micro-four thirds cameras are similarly constrained – despite the fact that its consumer camcorder division makes a little three CMOS camcorder, the SD700, that records AVCHD at 28Mbps (at 50/60p).

Both Panasonic and Sony also seem to have settled on AVCHD at 24Mbps for their compact professional camcorders, such as Sony's NXCAM or its upcoming DSLR-based Handycam NEX-VG10E (pictured). When Panasonic first showed a mock-up of its forthcoming 3D camcorder it had an AVC-Ultra logo (which would have meant recording up to 200Mbps), although AVC-Intra (at 100Mbps) would have been more than acceptable. Instead, the AG-3DA1 records 24Mbps AVCHD when even its consumer Mini-Me version (the new SD700-based HDC-SDT750) records at 28Mbps…

Bitrate hacked

The improvement a higher bitrate can make is easily seen on Panasonic's GH1 camera. It has been hacked to record at higher bitrates.

Andrew Reid of eoshd.com shot a test on the GH1 at ISO 1600 using both 1080/24p AVCHD at 44Mbps and 720/30p MJPEG at 70Mbps – both show a considerable improvement over the standard 17Mbps, although the AVCHD is a clear winner.

EOSHD GH1 High Bitrate Test - Low Light from Andrew Reid

Of course, HD DSLRs have other hurdles to overcome, not least aliasing and moiré patterns, which are evident on Reid's video. Panasonic promises to address this problem with the new AG-AF100 / AG-AF101 camcorder, which is based on the Micro Four Thirds sensor and lens system used by the GH1. However, the AG-AF101 is also limited to AVCHD 24Mbps 4:2:0. It also appears that Panasonic may have taken action to prevent the hack working on the most recent shipments of the GH1, so the AF101 may not be hackable either. Perhaps Panasonic should offer its own 44Mbps (or higher) version at a reasonable mark up.

The NEX-VG10E and AG-AF101 are just the first of several DSLR-inspired cameras coming over the next few months, and hopefully will inspire the likes of Nikon and Canon to respond with more video-friendly features, such as peaking and zebras to aid focusing and exposure, anti-aliasing, better audio controls, those higher bitrates or, at least, HDMI interfaces that allow non-compressed video to be recorded in a nanoFlash or similar higher bitrate recorder. CMOS sensors with less pronounced rolling shutter defects would be nice too.

Despite the problems, the artistic possibilities of HD DSLRs and their ilk can make all the hassle worthwhile. Canon's 5D Mark II, with its even larger full-frame 35mm sensor, was used to shoot the finale of last season's run of House. It had a noticeably different look to the standard film production, but worked well for what they wanted it to do. For the upcoming season of House the 5D will be used routinely on episodes, especially when they want a more intimate look. This certainly proves that the rapid adoption of HD DSLRs has not just been for cost reasons. It certainly hasn't been for ease of use….

Canon EOS 60D - more of the same

The new Canon EOS 60D has been designed to fill the gap you hadn't spotted between its existing EOS 550D and EOS 7D video-friendly models.

The end result will, in video terms, be essentially the same. However, it has a few new features that 7D owners (us…), will wish for, and might tempt some would-be 550D buyers to spend a little extra.

The most obvious feature is its articulating LCD screen, which will make it a lot easier to get low- or high-angle shots.

It also has full manual control of video settings, which is certainly nice creatively, and manual audio controls with the ability to turn off automatic gain control (it also has a stereo mic input), which would be a jolly useful addition to the external audio recorder you'll probably need to have anyway.

Otherwise, the picture quality (stills and video) seems to be unchanged from the 550D/7D. Is it a less expensive 7D without the tank-like build quality and a couple of features useful for stills, or a more expensive 550D with extra features and better build quality, or both…?

Specs: it records 1920x1080p HD video at 24, 25 and 30fps or 720p video at 50 and 60fps onto SDXC cards, using the MPEG-4 AVC, H.264 codec (.mov files) at 44mbps. It will list at $1,100 (body only) or $1,400 (with 18-135mm kit lens – a very nice lens with a useful range for video).

Canon has also announced an updated version of its EOS E1 plug-in for Apple's Final Cut Pro with support for the 60D. It converts recordings into ProRes 422 at least twice as fast as Apple’s standard conversion and allows logging with timecode, reel names and metadata. It also provides support for multi-core processing, for faster conversions on higher-powered Macs. It already works with the Canon 5D Mark II, 1D Mark IV, and 7D.

Sharp-cut Ruby wide-angle zoom lens

Focus Optics has developed a new wide zoom lens, the Ruby 14-24mm T2.8, which is claimed to be extremely sharp, especially at the wide end.

The Ruby is being exclusively distributed by Band Pro, and offers full coverage even for the F35 sensor. It weighs 1.36kg and measures 138mm long, with a front diameter of 110mm, and will accept a 102mm screw-in filter. The lens works on all 35mm PL mounted cameras, including the Sony F35, Arri, Red, and Canon D7, and fits the Canon D5 with an adapter.

Focus direction is reversed to go in the traditional cine direction and it offers longer focus travel at 126 degrees, using an anti-backlash design for accurate focus marks.

Hawk-Woods adapts to HD DSLRs

Hawk-Woods' new battery power adaptors for Canon's HD DSLRs will allow the cameras to be used with high-capacity broadcast batteries. The DC-5D adaptors for the Canon EOS 5D Mark II and EOS 7D cameras feature a cable mounted dummy LP-E6 type battery (as used in the DSLRs), which is linked to either a 2-pin D-Tap, or 4-Pin Hirose plug.

This allows the cameras to be powered from V-Lok (or other) types of battery when plugged into a suitable power output. This could be a rig mounted V-Lok plate, or stand alone V-Lok adaptor, like the Hawk-Woods VL-A1. This means that run-time can be increased immensely, especially for applications like time-lapse photography.

HD DSLRs - the film look on a budget

One of the most exciting developments of the past year, for those whose ambition is larger than their budget, has been the introduction of HD DSLR cameras that offer large sensors and a huge range of lenses for less than the price of a Sony EX1.

It was notable that about half of all the cameras on show at the February Broadcast Video Expo in London were HD DSLRs – the previous year there had only been one (on the Canon stand). Low-budget filmmakers were the first to realise the potential, but now programmes you might have heard of are using them.

For the rest of this article, read my full piece on HD DSLRs from the May issue of TVB Europe magazine in: HD DSLRs - the film look on a budget

The photo above is of Rodney Charters, cinematographer on 24, and Sam Nicholson, 24's visual effects supervisor, who are quoted in the article about their use of HD DSLRs on the series.

Cine lenses for HD DSLRs

Carl Zeiss is creating a set of prime (from 18mm to 85mm) and zoom lenses for HD DSLR cameras.

Its upcoming Compact Prime CP.2 and Lightweight Zoom LWZ.2 lenses will have interchangeable mounts that can be used with Canon EF, Nikon F, and PL-mount cameras.

The primes can be used on full frame cameras (like the Canon 5D Mark II), and will all open to T2.1 (although in the press photograph of the lenses, the 85mm is shown as a T1.5). However, the 15.5-45mm/T2.6 zoom lens can only be used with crop sensors (such as on the Canon EOS 7D – up to 24.9x18.7mm, a Super 35mm film frame). The zoom will weigh about 2kg, which makes it useful for Steadicam applications. Thanks to the interchangeable mounts, the lenses should be very attractive to hire companies, as they will cover a wide range of traditional cine cameras and HD DSLRs.

Prices are likely to be at least as much as many of the cameras they are fitted to, and they should be available from June.

Being designed for moviemaking, they will be a lot easier to use than stills lenses, especially for focusing, with longer focus rotation (making it a lot easier to be precise – particularly for manual use).

The iris opening in the prime lenses uses 14 high-precision blades, which stay consistently round and symmetrical over the entire T-stop range. This should translate into natural and pleasing out-of-focus highlights and a smooth bokeh (the ring around the blurred highlights). The lens design and tight tolerances are claimed to "ensure low distortion, high resolution and excellent colour rendition for sharp, punchy images."

HD DSLRs: Still developing

Review of the Canon EOS 7D - DSLR Camera

There has been a lot of interest amongst video users in digital stills cameras recently, mainly because DSLR camera manufacturers like Canon, Nikon and Pentax have brought out reasonably priced, large sensor models that can record HD. Now, if you want a 35mm camera that can shoot HD (720p or 1080p), and take different lenses, you can buy one for less than the price of a used Sony EX1.

Canon has been the major player, especially with its 5D mark II, although that only records at 30 frames per second. We have been promised a firmware upgrade which should add 24 and 25fps - possibly due April 2010.

However, the latest Canon EOS 7D already has all the frame rates, and costs less, although it has a smaller sensor (APS-C, about 23x15mm).

It is an impressive stills camera, but while its 18-megapixel CMOS image sensor is great for still images, CMOS is not so suitable for video (although many video cameras have them). One of its problems is skew. This happens when you pan the camera and verticals don't look vertical on recording because the CMOS sensor reads line by line rather than all at once.
Some users may also notice aliasing. 

But, in the right hands DSLRs can produce stunning results.




The Canon EOS 7D It is not exactly a light camera (it weighs about 1.39kg with an 18-135mm zoom lens). Even with the image stabilisation in the lens switched on it was tricky to hold still because you couldn't hold it up to your eye (in video mode it only uses the rear LCD) so, it went on my Miller tripod and stayed there.

The 7D offers ISO speeds of 100-6,400, expandable to 12,800. My first thoughts were that any image taken at such a high ISO would be very grainy – but the camera's DIGIC 4 processors remove colour and luminance noise to give a cleaner image.

It has the usual optical eyepiece and a 3-inch LCD with 920,000 dots. I'm used to staring at LCD screens on cameras like the Sony HVR-Z1 with only 250,000 dots, so the Canon's screen was a joy to watch. Unfortunately, it is shiny and you do get a lot of reflections that are distracting when trying to shoot. If you were seriously considering buying this camera (or any of the other DSLRs) for video work you should take a look at the Zacuto Z-finder V2. It will keep out the light from the screen and, importantly, act as an extra point of contact with your body, for stability, if you are going hand held.

For video the camera uses MPEG4 AVC encoding wrapped up in a .mov file, and records onto Compact Flash cards at up to 45Mbps.

This is not a format to edit with. So, you'll need to consider software to convert it to something more edit friendly. MPEG Streamclip from Squared 5 gets consistently good reviews and is free.

In HD mode you can only record about 12 minutes of video on a 4GB card. There is only one card slot – so you can't hot swap like a Panasonic P2 camera or Sony EX. Buying a bigger card won't necessarily solve the problem, as the camera will stop recording once the file size reaches 4GB. So this might not be the perfect camera for doing that 'locked off shot'.

Stills cameras have been able to shoot video for some time – although not very well. But now the technology has improved and it is hard to deny that the results can be very good. I recommend you type 'Canon EOS 7D' into the www.vimeo.com website search box so that you can see some incredible results. If you shoot news and docs look at Guardian photographer Dan Chung's work on Vimeo and http://www.dslrnewsshooter.com

If you are a Mac user there is a lot of help getting your footage from camera into Final Cut Pro. One very helpful page is on Chris Fenwicks site. Vincent Laforet is also very helpful with advice and mentioned an upcoming new plug in (again for FCP).

The audio however is a different story. The camera does have an on board microphone which may come in handy as a guide track but it definitely won't be good enough for broadcast, it will also pick up camera handling noise and wind noise.

You really do need to record the audio on a separate recorder. Trawling through the forums it looks like most people buy the Zoom H4n. It has its own built in stereo mic, if all you need is some atmos. But, it also has two XLR sockets and can record at 48kHz, which should keep your editing software happy. With a splitter you can take an output from the Zoom for monitoring and feed the recorded audio in to the camera as a guide track for synching later. The problem is where do you put it? Maybe it might signal the return of the sound recordist.

You can swap info with other Zoom users at the Zoom forum.

If you don't want to be tethered to the recorder. Then you'd better brush the dust off your clapper board as it will once again come in handy to sync sound with vision. Funny how the more technology improves the more we rely on the old ways of working.

The evolution of the video camera has given us a body shape and layout that puts everything you need just where you want it. The iris, gain and white balance can be found without even taking your eye from its fully adjustable viewfinder.

I know many GTC members hate the Sony Z1 type cameras because of (amongst other things) their shape. But these DSLRs are even trickier to hand hold for any length of time. Unless you have the arms of a weight lifter you'll also need some sort of rig to make it feel more like a shoulder-mounted camera. Add in the cost of the viewfinder and your cheap video camera starts to look a little more expensive.

Rigs available include:
Check out their sites for demonstrations of how to use the kit and examples of user's videos.

But, if your budget is tight, start with a good old fashioned tripod. I used the camera on a weeks holiday and to keep the weight down I used my Manfrotto 561B monopod (which has feet!).



There is no peaking to help with focusing (and, even if you wanted to, Canon doesn't recommend using auto focusing when the camera is in movie mode.) There are no zebra stripes either, but there is a histogram which takes up about 1/9th of the screen. If you are used to using a shoulder mounted camera then using a DSLR will require some time to acclimatise.

Certainly, if you intend to use the camera, I recommend you download the manual (and any drivers you may need) and have a play with the camera before the shoot. For example, it took me a while to work out how to manually white balance. It isn't intuitive. 

You can also watch simple tutorials on the EOS 7D at Canon's USA site. 

Why buy one of these cameras?

Lenses, lenses and lenses. The range of lenses you can get for a DSLR is eye watering, but the prices generally aren't. So, if the director needs a one off special shot in a difficult location this camera could make you the hero of the hour.

I'd recommend you read photographer Doug Klostermann's page on "Why You Shouldn’t Buy the Kit Lens".

If one thing stands out, it is the possibility of very shallow depth of field. It seems everyone wants that film look and with 24p and a little help in post – you can have it at a relatively cheap price. The camera body costs around £1,200.

Time lapse on these cameras is stunning. If you are a timelapse newbie, start with Timothy Allen's starter guide. Take a look at the some great examples of DSLR timelapse by Tom Lowe at TimeScapes.


And if you mix timelapse and HDR (high dynamic range) photography - the results can be beautiful.

If you set the camera to record the largest still image size (5184x3456 pixels) you can import the time lapse stills into your editing software and pan and scan around the video. For a tutorial on how to do this on a Mac, Philip Bloom comes to the rescue. 



However, for timelapse you will have to spend about £100 extra on an intervalometer remote control unit to tell the camera when and how often to take each still image.

If money is tight, this camera may be all your low budget production can afford, and some people have shot incredible footage on it. It is not primarily designed to be a video camera, which means almost everything you do with it will be some sort of workaround, but considering the price, it could be worth the effort.

Would I buy one? 
I originally had a camera on loan from Canon for a week to write this review for the Guild of Television Cameramen's magazine, Zerb. I genuinely liked the camera - enough to buy it. I'm still experimenting with it and it really is essential to have the Zacuto Z-finder, which I now have on order.
