I recently sold a lens to someone and they returned it saying that there was lens separation. I don't see it and I'm a bit embarrassed to tell you the truth. I can spot bad separation but not minor separation, I guess. I asked a friend to seek his opinion ind he can't see spot it either but neither of us are "experts". Well it was a clean transaction and clean refund so there is no dispute. I'll keep the lens because it takes nice pictures but I want to know for my own sake and perhaps get a third opinion. This is an old Contax RF 50mm f1.5 Sonnar that I bought from keh.com (if that matters) in brg or ex condition, I don't remember. So can anyone in the bay area inspect my lens? You can PM me and we can arrange a meeting somewhere if you are willing. I thought about going to a photography store but I'm not sure if that is appropriate. I feel like it is asking a mechanic to check up on a car for free. If this is in the wrong forum then can a mod please move this to the appropriate one.
