I have an FD 50mm 1.8 S.C. breech lock mount lens on it. Problem 1: I have been trying to lock the exposure by pressing and holding the exposure memory switch recompose and then press the shutter all the way. I can see the exposure values changing in the viewfinder and the exposure is done with the new values (e.g. I have tried to lock 1/60 sec at f/11 and it fires at 1/60 sec at f/1.8). Problem 2. Trying a DOF preview, I move away from A the aperture ring, press the exposure preview switch, but the lens does not stop down. Am doing things wrong, or my A-1 is broken?
