Cannot say much more than you would understand just by looking at this camera. Do not remember where I bought it, or (more disturbing) why. Never shot a film through it, but I suspect it is still in good shape for its age.
Apertures run from 2.8 to 16, the shutter is automatically selected by means of a coupled meter, when in A mode. Shutter speeds themselves being 1/30, 1/60, 1/125 and 1/250, one may choose to employ manual shooting, by manually selecting a shutter speed and its corresponding/desired shutter speed. Each shutter speed has its own corresponding apertures in 3 sets. And by the way, this is a distance focus camera, which means you have to guesstimate the distance to your own subject.
For shutter release, just trip that knobby lever on the right side of the lens.
