Canon has apparently been reading the numerous forum posts where 5D Mark II users have requested – nay, demanded – manual exposure control for their videos. Well an email from Canon USA has confirmed that it’s coming . . . in June to be exact.
Canon will issue a firmware update to enable full manual exposure controls while shooting video, including ISO, aperture and shutter speed. Although, I’m not sure what they mean by shutter speed. Isn’t the shutter always open in video mode?
