<p>Hello,</p> <p>I recently bought a second hand canon AE1 program with so FD lenses. One of the lenses was a canon 50mm f1.8 FD with the "new" mounting type (see image here: http://en.wikipedia.org/wiki/File:Canon_FD_lens_rear.jpg).<br> The lens looked new and the person selling the camera told me that it was her mother's so wasn't sure how often it as been used.<br> I has a quick look at home and came to the conclusion that it probably hasn't been used at all. there is no signs on the mount and everything is very shiny.<br> I tried to put the lens on the camera and couldn't do it. I tried on my A1 and still couldn't attach it.<br> I had a look at the lens and understood immediately, the 2 red dots on the lens, the one on the side and the one on the mount of the lens, are not at the same position (or in line) but there is an approximate 45 degree angle between them. As a result, the little dent that is supposed to insert in the camera mount was not in line either and the lens can't be inserted all the way in and so I can't rotate it to lock it.</p> <p>Because the lens seems brand new, I was wondering if it is something that is known about this type of FD lenses and if it worth having it repaired considering how cheep these lenses are on ebay?</p> <p>I should mention that I tried to unscrew the 3 little screw near the lens mount but they are very tight with no sign of damage on the paint.</p> <p>Thanks,<br> David</p>
