If you use a remote release, Item C3 in the menu should solve your problem. You can choose from several time intervals before the release reverts to zero. I have been using this lately trying to photograph meteor trails. No apparent problems with star fields, but when I shot half a dozen eight second exposures of the Space Station crossing the field of view I saw a definite hook at the beginning of each trail on each exposure. That hook I can only surmise is from camera movement caused by the mirror? movement, yet I would have supposed the camera to have settled during the two second delay. Also, I was using the Live View so the mirror should have been up already? I was using a manual focus lens with the Manual setting and a reasonably stable tripod. Tom Forker Washington State.
