Lenses and Shutters
The Mamiya Six was manufactured in a wide range of lenses and shutters. That holds particularly true for the pre-War and War period, when prospective buyers could even bring in their own shutters and lenses to be fitted. Note that the lens and shutter combinations have been arranged alphabetically, not chronologically.
