Canon MF 100mm f2 - Canomatic - $200 (Greeley)
I was given this lens by the grandson of the original owner while back home in Washington. While its neat and all, I just don't have a use for it as I use another 100/2. Don't get me wrong, this is a pretty great lens. I am using it on my a7, and I will include the modified adapter to let it mount to any e-mount body.
