I recently bought a Mamiya 645-1000S with a metered prism finder. I cannot find any user's manual that addresses this particular model of finder, and cannot even identify it for sure; apparently there were a number of versions manufactured: PD, CdS, AE, AE-S, etc. I've looked through all the stuff available online and all I've seen have a shutter speed set knob on the finder, but this one does not. It has only the film speed set knob and an "on/off" knob with a white button in the middle of it. There are no LEDs in the viewfinder but a needle that indicates shutter speed, so it must work as aperture priority only. Anyone know where I can get a manual for this? The one on Butkus's site is the wrong model.
Maybe someone can advise me: I just ran a test roll through it. The meter readings are accurate when compared to my hand-held meter readings, and in manual mode I got good and consistent exposures at all shutter speed/f stop combinations from 1/8 to 1/500 sec. The automatic mode does not seem to work - negatives got progressively thinner as I stopped down. I've covered all the obvious bases; the lens and shutter speed select are both on auto and the linkage fork/pin on the lens is engaged.
I may be missing something here - like what the heck is the white button supposed to do?
