Hello! My name is Gia. I am a beginner with basic knowledge of how to work a manual film camera. I went to an old thrift store and picked up and old working in excellent condition Olympus 35 IVA (all manual) camera. It is from 1953. Not sure what kind of camera it is, if it is an slr, but my research has only stated that it is a viewfinder. I have fiddled around with the camera well enough to know how it works, and that it does shoot. The only problem is manually focusing this camera. I know some cameras without autofocus feature the manual focus in which you would have to superimpose one screen onto another screen and that would be your "focus" but with this camera, while I look through the view finder, even if I twist my range (ft.) there is not two screens or anything that I have to match up. Also, if it helps, this camera does not have a light meter or a range finder. My question is, how do I focus this old guy? Do I just set aperture, shutterspeed and Iso, and find the range of my subject and shoot? Or is it more complicated then that? I hope someone with more experience in older cameras can show me exactly how it is done I do not want to waste any shots!
