Bronica GS-1 telephoto lens for 6x7 medium format with leaf shutter and 250mm reach.
The Bronica Zenzanon-PG 250mm f/5.6 is a telephoto lens for the Bronica GS-1 6x7 medium format system, providing approximately a 125mm equivalent perspective on the generous 6x7cm format. The PG designation indicates the lens series designed specifically for the GS-1 body.
Optical quality is good with the Zenzanon multi-coating delivering sharp, contrasty images at the telephoto distance. On the 6x7 format, the 250mm provides useful reach for portrait, wildlife, and landscape photography where medium format detail and tonal richness add significant value to the captured image.
Build quality follows Bronica's professional standards with solid metal construction and a leaf shutter built into the lens for full flash synchronisation at all speeds. The bayonet mount ensures secure attachment to GS-1 bodies. The lens is substantial but well-balanced for the large GS-1 system.
On the used market, the Zenzanon-PG 250mm f/5.6 offers medium format telephoto capability for the Bronica GS-1 at modest prices. For GS-1 users wanting telephoto reach on the 6x7 format, it provides the image quality advantages of the large negative with practical telephoto compression.
