Magic Lantern adds experimental firmware offering 4K RAW to EOS 5D Mark III
Magic Lantern has released an experimental build of their firmware that offers 4K RAW recording on the Canon EOS 5D Mark III. Also within the build is a Live View mode that shoots at 5796x3870 at 7.4 fps, even at faster shutter speeds. This will produce rolling shutter however. Magic Lantern point out that the current build has “plenty of bugs,” but expect that these will be worked out over time.
