it's a nice little, fully manual, film SLR. you have the 2000 model which has shutter speeds upto 1/2000. (FX-3 model has max shutter speed of 1/1000)
only way to test it would be to put in a roll of film and shoot. The camera is fully manual, i.e. you set aperture and shutter speeds. it does have a meter, centre weighted (i think), which gives you and indication of your exposure. it's been a while since i've used mine so i can't recall what the display was on the view finder (whether it was over and under lights or shutter speeds.)
good thing about this camera is that it can use contax mount lenses (if one can afford them).
a decent body will fetch about $100 - $150 (last i checked, which was a couple of years ago)
