Mamiya RZ67 6×6 Viewfinder Mask

Mamiya RZ67 6×6 Square-Format Viewfinder Mask

Think square.

This newly manufactured viewfinder mask provides a clear 6×6 square-format framing reference for photographers using a compatible 6×6 back or square-format configuration with the Mamiya RZ67.

The RZ67 was born as a 6×7 camera, with a large rectangular ground glass designed around that generous image area. But the modular nature of the system also opens the door to less conventional formats—including the classic square.

This mask clearly defines the 6×6 image area within the larger RZ67 viewing screen, allowing you to compose square at the moment of exposure rather than cropping by estimation later.

Features:

* Designed for the Mamiya RZ67

* Provides a clear 6×6 square-format framing reference

* Ideal for compatible 6×6 backs and square-format configurations

* Clearly defines the square image within the larger 6×7 ground glass

* Makes composition faster and more repeatable

* 3D printed for a precise, lightweight fit

* Finished in Black to minimize distraction while composing

* Installs without permanently modifying your camera

* Newly manufactured accessory — not used or salvaged

Compose square. Shoot square.

There is something fundamentally different about composing for a square at the moment the photograph is made. Balance changes. Negative space changes. The relationship between the center and the edges changes.

Rather than shooting 6×7 and deciding on a square crop afterward, this mask lets you see the photograph as a square from the beginning.

For photographers experimenting with uncommon backs, adapters, or dedicated 6×6 configurations on the RZ67, it provides the simple visual boundary that the original 6×7 focusing screen doesn’t.

Manufactured by Anderson Island Films as part of our effort to keep classic photographic equipment useful, adaptable, and in circulation.
