I found this lens at Goodwill. It had oily aperture blades so I completely disassembled and CLA'd it. Probably a waste of time for such a low-value lens, but it does mean I can guarantee it's in perfect working order. The optics are pristine save for a TINY bit of dust and a small transparent splotch of separation (I think) on the edge of the rear element, which won't affect anything. Aside from that it's mint. I even re-glued the rubber grip.
