It mentions a HD movie mode, no other details other than a quoted 2 hours worth of movie shooting . Oh well, there goes my BP-511A collection . More power is always good though, especially when travelling with IS lenses. EDIT: auto vignetting correction like the D3 generation, and it says the 5D mk II will shoot at 3.9FPS with it on.
