For what it is worth. I'll add to this thread that I ruined about 50 of the first shots today....multi exposed, all in a row. Augh!!!
No idea how I did it... but I know I must have. I switched drive modes from single to high, then back to low speed because the buffer was filling too fast. Somewhere in that fiddling, I must have bumped the multiexposure button (not even sure where it is, I've never used it, but I'm gonna look!) I think the slow buffer saved my butt, and when I switched it back go low speed drive mode, I must have disengaged multiexposure.
One of my problems could be the way I carry between shots, I can bump the four way with my pinky knucle at times when I am using my camera strap as a wrist strap wound around my wrist a few times for walking around. Grumble grumble... I hate it when I shoot myself in the foot, no one else to blame. Grrrr
The funny thing is, I remember briefly chimping some shots to just verify exposure was in the ballpark, and I didnt have my glasses on and look at details and somehow missed it. I shoot raw plus jpg, and both are the same. Bummer,
