Zenza Bronica GS-1 6x6 Viewfinder Mask Guide

For the Bronica GS-1 6x7 Camera - all viewfinders. This mask allows you to have a guide for shooting 6x6, whether you're using a 6x7 or 6x6 film back. I used clear PLA, but any color/material could be used. CAREFULLY set it on top of your focus screen and put your viewfinder of choice back on the camera.
