My grandfather this christmas gave me my late grandmothers cameras from what i can only guess was the mid 1970s. These are a Nikon EM and a Minolta SRT101 Now my grandmother was a neurotic saver of things, and took amazing care of everything she owned. The Ziploc family went to college on her dime. So here is what i have learned so far about these cameras. The Nikon is lighter and smaller so im probably gonna use it more simply for that fact. It does not have a shutter speed dial, which is weird to me. It seems to do its own automatic timing, and i dont know if i like this. The minolta is heavyer but it has teh shutter speed control. It has a different focusing crosshairs. I dont know what you call it, but the nikon has a sorta circle with the top and bottom halves divided until the target comes in focus. Im hoping camera people will have a word for this, because it is hard to describe. Both seem to work perfectly from what i can tell, though i havent developed a roll from either. My question is: are either of these cameras particularly rare? Also what should i expect to pay for a camera tuneup?
