I don’t shoot videos with my DSLR cameras, but it’s nice anyway that Magic Lantern has created reversible firmware to add RAW video to the Canon 50D, since I own one:
I have a lot of high-capacity pro Lexar and Sandisk CF cards, so I will probably keep using the 50D and other bodies from that era as long as they continue to function.
Slashdot has an interesting comment on why Magic Lantern used a Nikon lens while testing Canon bodies, and why manual-focus, non-zoom lenses are best for shooting video.
(Colleagues of mine who are shopping for a DSLR generally say they want video capability for recording family events. High WAF.)
