The Bronica Zenzanon 150mm f/3.5 is a telephoto lens for the Bronica ETR 6x4.5 medium format system, providing approximately a 120mm equivalent perspective.

Optical quality is good with the Zenzanon multi-coating delivering sharp, well-corrected images. The 150mm focal length on 645 provides classic portrait telephoto compression that flatters subjects. A built-in leaf shutter enables flash sync at all speeds for studio and location portrait work.
Build quality follows Bronica's professional standards with solid construction and the ETR bayonet mount. The lens handles well on ETR bodies and provides smooth focus ring operation for precise manual focusing at portrait distances.
On the used market, the Zenzanon 150mm f/3.5 offers affordable medium format portrait telephoto capability. For Bronica ETR users wanting a dedicated portrait lens, it provides the compression and format advantages of 645 medium format at very accessible prices.
