What a great find! I love old cameras, the texture really adds to your photo!

I don't know to what extent your newfound lens from your mom is broken--- Does it not even take a photo, or does it not autofocus? Some older lenses do not have a motor in them, and therefore you have to manually focus--- the lens might be fine afterall! I took a bunch of my dad's old Minolta lenses, and using a converter, am able to use them on my Nikon SLR. Unfortunately, because they came from a 35mm camera, there is no autofocus, but that's ok-- I saved hundreds!
Great blog so far, and thanks for stopping by my 365 project!
