Rolleiflex 3.5f Camera 135 Format Viewfinder Mask

This is a straightforward model, a viewfinder mask for the Rolleiflex 3.5f camera when shooting 135 format film. When employing a medium format camera held vertically to capture horizontal 135 format images, the viewfinder presents an inverted image in all orientations, rendering composition exceedingly difficult. Integrating this viewfinder mask significantly eases the effort required to align your shots. The mask is designed for vertical placement and securely fits into the space located at the base of the viewfinder assembly.

I utilize this myself and extend my best wishes for everyone to capture many outstanding photographs!
