I acquired a rather Large collection of 35mm cameras, Subminiature Cameras, Cam Corders, lenses and accessories that I have no knowledge of (Never used any of these cameras or Accessories), so I will detail what I know. Any questions, please ask prior to your purchase as I may be able to answer. If there was any testing done, it will be identified in the following detailed listing, Otherwise assume it was not tested.   .
