I want to refer to an older thread:http://www.canonrumors.com/forum/index.php?topic=5599.msg107127#msg107127
Why can't you have mirror lockup enabled with AEB and a 2-second timer? Wouldn't you want the mirror locked-up between shots if you are doing a bracketed scene on a tripod? I guess they figure the AEB is for shorter exposures than would matter on a tripod?
Thanks for your answer(s).
