PLEASE DO NOT LINK THIS PAGE UNTIL FINISHED--MY SANDBOX IS OVERFLOWING

This page provides a visual overview over the various design elements of the Mamiya Six series of folding cameras. The images have been provided to allow the use an accurate identification of the various models and variants. You are strongly advised to use the dichotomous key provided on the main Mamiya Six page, as this will guide you in the identification of models.

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.
