Pinhole lens for CONTAX G1 It works fine on the G1, but it seems the shutter doesn't fire when attached to the G2. This is a lens my father used. I'm not very knowledgeable, so please judge from the photos. It was stored neatly on a shelf, so I think it's relatively clean. Recently, there have been many return troubles on Mercari, so I'm very sorry, but I would like to ask that you refrain from returns. There is no case or instruction manual. Please feel free to contact me with any questions, and I will answer them to the best of my ability. It is a beautiful item, but please consider that it is not new. #AVENON #Pinhole lens Other features: Only a filter on the front, no cap, and a rear lens cap included.
