Hi all. First time here. I just acquired an old Nikon EM 35mm camera with a few lens (45mm, 50mm, 135mm), but I'm not sure if specific cameras require specific lenses. All the lenses that came in this batch are from Konica and Vivatar. I haven't tested the camera with any film, yet. What I have noticed is no matter which lenses I put on the EM, I can't get a proper focus from anything far away. Take the 50mm for example. I have been reading that these are the norm for taking standard pictures near you. Yet I can't focus on to anything unless it is about 6 inches away from the lenses. So should I be seeking Nikon specific lenses, or could there be some other problem with the optics within the camera? It is a pretty simply camera, so I don't think there is any other setting I have missed for focusing through the view finder. Thanks.
