Magic Lantern brings 14 Bit RAW video to the 5Dmk2!!!! (& 5Dmk3)
The Magic Lantern community has developed firmware for the 5Dmk2 and mk3 that allows the camera to shoot 14bit RAW video in 25p! Whilst the firmware allows the 5DMk3 to capture 14bit RAW in 1920x1080 in 25p, the 5Dmk2 is limited to 1880 x 720 RAW at 25p - which is still an amazing achievement. As you will see from my tests, this resolution creates an image that is closer to the cinemascope aspect ratio of 2.35:1, and is still perfectly usable. My tests of the Magic Lantern firmware were conducted on a Canon 5DMk2 with a Leica R 21mm/4 lens, and the same shot was also captured using the Official Canon firmware in the Neutral and Cinestyle picture profiles (scaled to 1880 x 720).
What is clear to me is that the 14bit RAW image contains a HUGE amount of colour information, greater dynamic range and a cleaner, sharper image. I think that this particular shot provides a very clear comparison of the greater dynamic range that the firmware provides. Pay particular attention to the window at the top left of the frame - with the Neutral picture profile the window is almost completely blown out, whereas more detail is retained in the area in the Cinestyle shot. The detail and colour in that area in the Magic Lantern RAW shot is astonishing and is an excellent example of the greater dynamic range you get with this firmware. For the RAW shots I post processed the RAW file using a simple tutorial provided by Cinema5D here, which allows you to go from RAW to Prores in a few simple steps.
