It's a very exciting time right now for Canon dslr owners. The team at Magic Lantern have now made it possible to shoot experimental raw 4k on the five year old camera.
Okay! Straight to the point, the following resolutions and frame rates are now possible.
1920x960 @ 50p (both 1:1 crop and full-frame - 3x3 pixel binning)
1920x800 @ 60p (same as above)
1920x1080 @ 45p and 48p (3x3 binning)
1920x1920 @ 24p (1:1 square crop)
3072x1920 @ 24p (1:1 crop)
3840x1600 @ 24p (1:1 crop)
4096x2560 @ 12.5p (1:1 crop)
4096x1440 @ 25p (1:1 crop)

Having heard this news, I hastily dusted off my dslr and installed the latest experimental build and tried it out in my neighborhood. I will have new sample footage in the coming days. Compared to other previous builds, it requires a little bit more work to get the final workable image for post-production. It requires a bit of command_prompt code, whereas previous RAW workflows already have open-source DNGconverters for previous builds of ML.
Here are some shots of the March 30th stable build. Look forward to new sample footage soon.
