Hi everybody I'm looking for a waist level finder for my canon f-1 (the "old" mechanical version, not the "new" f-1) . I have no idea what they are worth, but hopefully not a lot cause I don't have any money! Hope someone out there has one they don't need. I have a few things I can trade with. A canon fd 135mm f3.5 in great condition. a canon fd 50mm s.c. 1.8 in ok condition. An m42 yashinon 50mm f1.7 in great working condition. An m42 cosinon 50mm f1.8 in great working condition. an m42 chinon 35mm f2.8 lens in great working condition. That's about it I guess. I do have a tiny bit of cash that I can shelf out too.
