Sony's new HDC-4300 system camera, aimed at sports and events
broadcasting, is touted as “the world’s first camera to use three 2/3-inch 4K
image sensors” [the Hitachi SK-UHD4000, which is already in use, has four
sensors: one red, one blue and two green for extra sensitivity].
The HDC-4300 also offers up to 8x Super-Slow Motion in HD
(at frame rates up to 479.52/400fps), which will make it a useful HD camera to
have for today’s mainstream productions. It can do 50/60p in Ultra HD. Both the
4K and 8x capabilities are on a paid-for license (which can be bought on a
weekly, monthly or permanent basis), so if you don’t need them from the start,
you don’t need to pay for them until you do. It comes standard with 2x and 3x
HD recording.
Having 2/3-inch sensors is important for sports production,
in particular, because cameras have to follow action that can be quite a
distance away (using lenses that have up to 100x magnification), where using a
typical, larger sensor 4K camera means there is very little depth of field for
focusing, especially if the lens is wide open, as it usually will be for games
at night. Using smaller sensors, as found in all current HD system cameras,
means a fast moving player is more likely to remain in focus. There is also a
dynamic focus (focus-assist function) for use in UHD, where a focus point can
be displayed on the viewfinder with a marker for easy focusing.
The HDC-4300 supports the same B4-mount lenses and the same
control surfaces as Sony’s mainstream HDC-2000 series cameras, and the existing
HDLA-1500 series, control and shading systems, viewfinders and master set-up
units are all interchangeable between the HD and UHD systems. This means it
offers all the same camera angles, zoom ranges and iris settings.
“This camera provides 4K capabilities and a workflow that
content producers are instantly familiar and comfortable with,” said Norbert
Paquet, Strategic Marketing Manager, Sony Professional, Sony Europe. “We’ve
developed the HDC Series as a flexible platform for our customers to maximize
their ROI on multiple applications. The HDC-4300 is multi-format for daily HD
applications, sports on the weekends with up to 400fps, and future proof with
4K acquisition.”
It also supports the widened colour space included in the next-generation
ITU-R BT.2020 broadcast standard, which will help to future proof master
recordings and post-production options.
The HDC-4300 also allows for HD cut outs of two full HD
images from the UHD picture in real time, including a selectable zoom and
perspective mode.
Other features include: Auto lens aberration compensation 2
(ALAC2); Colour reproduction adjustment; Gamma table selection; User gamma; Natural
skin-tone detail; Knee saturation; and Low-key saturation.
The HDC-4300 should be available this Summer, and is likely
to cost about $80,000.
Note: Ultra HD (3840x2160) is four times the resolution of
HD (1920x1080), although Sony calls both UHD and Cinema 4K (the Digital Cinema
Initiative standard, which is 4096x2160), 4K just to confuse matters - or
rather, so as not to confuse consumers of its 4K (UHD) televisions. So, it is
just possible that the HDC-4300 can also shoot 4096x2160, but as UHD will be
the broadcast standard this is unlikely - however, Sony hasn’t revealed the
full specifications yet.
4 times the security
In other NAB news, Sony has announced its first Ultra HD
security camera, the SNC-VM772R, which boasts excellent sensitivity in low
light (down to 0.1 lux - there is also a built-in infrared light source for
night time shooting).
It has a single 1-inch back Illuminated Exmor R CMOS image
sensor, and uses bandwidth optimization (for streaming the pictures back to
base over limited bandwidth) and intelligent scene capture to improve picture
quality. It also has a 2.9x motorized zoom lens with optical image
stabilization. An Evidence Shot mode lets users see critical moments in the
camera’s highest resolution of 20MP in still shot mode - 2.4x more pixel
resolution than UHD.
“4K is the new video security standard,” said Katsunori
Yamanouchi, Vice President, Sony Professional Solutions Europe. “But 4K imaging
is about more than just increased resolution. It’s also expanding the
application potential of security cameras and helping to transform security and
surveillance. The increased resolution covers a larger area, improving
situational awareness and ensuring nothing is missed. These benefits help
security professionals reduce installation and operating costs as fewer cameras
are needed for specific areas.”
