Magic Lantern Xmas Edition firmware is available here. It is available for 60D, 50D, 600D (T3i), 550D (T2i) and 500D (T1i).
Team Magic Lantern is bringing HDR video recording on select Canon DSLRs. This Magic Lantern firmware will be available for Canon 550D (T2i), 600D (T3i), and 60D DSLRs starting 2011-12-22 at 22:12 GMT. For my fellow Pacific Timers, that’s 1412 hours or 02:12 PM. Magic Lantern firmware can be downloaded here.
I have a Canon EOS 60D that I can install the firmware on.
