Zenza Bronica Prism Viewfinder G for GS-1

The Zenza Bronica Prism Viewfinder G is a must-have accessory for any Bronica GS-1 shooter looking to level up from the waist-level finder. Designed specifically for the 6x7 GS-1 medium format system, this prism provides an eye-level, upright, and laterally correct view, making handheld shooting far more natural—especially for portrait work or faster-paced environments where a waist-level finder slows you down.

This is the standard non-metered version of the Prism G. It adds minimal weight and balances nicely on the GS-1 body. If you’re working with flash or studio setups and already metering externally (or using a digital back), this finder gives you the clarity and ergonomics without the fuss.
