I have a new-to-me SQA and I'm having a few problems with the mirror lockup.

Could someone give me the sequence of things regarding using the lock up?

I followed the manual, but my trouble seems to be that the shutter doesn't fire if I have it in "S" position. I have to return to N to reset things, then I have to advance to the next frame and I suspect that the shutter has fired and cocked all over again. I'm losing a few frames of film (more than a few) trying to figure it out.

I tried in "C" and things are fine, as the shutter closes, mirror lifts and I can fire the shutter and then it recocks and stays closed for next exposure. This isn't very practical for case by case photos, though.

I've never used this type of system before, being more accustomed to my twin lens reflex or 35 mm camera. I hope I posed the question correctly.

Thanks in advance.

In the S position, the mirror will return when you wind the film for the next exposure, in the C position, the mirror will stay up until you move the level back to N (or you can put the lever back to S and it will drop when you wind on).

Wind the film BEFORE setting to S or the mirror will drop as soon as you advance the film/cock the camera.

With the lever in the C position, the mirror will drop and pop back up as you wind the film - that's completely normal.
