Canon has introduced a new, entry-level HD DSLR that will cut the cost of shooting full HD, taking it well below the price of any semi-professional camcorder. The new EOS 550D (Canon Rebel T2i in the US) camera will probably be available for under £800, including a kit lens, when it ships on February 24. 
It uses a newly developed 18 Megapixel APS-C (22.3x14.9mm) CMOS sensor (more than five times the size of the 2/3-inch sensors commonly found in broadcast cameras), with Canon’s advanced DIGIC 4 14-bit image processor, as used in the larger 7D (which we used to shoot our video at the Canon event).
Users can record 1920x1080 at 24, 25 or 30 frames per second, or 720p at 50 or 60fps. As seen with the 7D, the 550D Rebel T2i should produce excellent pictures in low light – it can record at ISO settings of 100 – 6400 (expandable to 12800), with noise reduction delivering clean looking images. It also has a 3.5mm stereo microphone socket for an external microphone.
Highlight tone priority can be set independently for movie capture, without changing any still image capture settings. The 550D Rebel T2i also has a new Movie Crop function that records with the central 640x480 pixel area of the sensor, giving 7x magnification, however this isn't available for HD recording (where it would probably have to be 4x or 5x – perhaps an HD version is something for the future).
From an ergonomic point of view, the smaller size, and lighter weight (530g body) of the 550D Rebel T2i, may make it easier to hold than Canon's existing, larger, HD DSLRs.For video output, there is a mini HDMI port, but this doesn't give access to the uncompressed video signal (for recording to an external recorder). Recording, to a SDHC card, uses the .MOV format with H.264 video and Linear PCM audio at 45Mbps (for a maximum duration of 30 minutes or 4GB file size).
There is also a 3-inch 720x480 pixel LCD screen (which has to be used in video mode as the conventional viewfinder can't be used because the internal mirror is locked up).
Plugging in to FCP
Canon has also announced a new EOS Movie plug-in for Final Cut Pro, to enable quicker and easier editing of EOS footage. A free Beta release of the plug-in will be available to download in March.
The plug-in will enable the log and transfer of video footage from the EOS 5D Mark II, EOS 7D, EOS-1D Mark IV and the 550D, and convert the recordings to Apple’s high quality ProRes 422 codec at approximately twice the speed of Apple’s standard conversion. Users will also be able to add timecode, reel names and metadata.
