Bronica 150mm F/4 Zenzanon-PG Lens For GS-1 6x7 Camera Review

The Bronica 150mm F/4 Zenzanon-PG is a medium telephoto lens designed for the Bronica GS-1 6x7 medium format system. With a 72mm filter thread and an aperture of f/4, it delivers the classic rendering and build quality associated with Bronica's PG-series glass. This focal length sits in the portrait and detail range for the 6x7 format, offering moderate compression and subject isolation without the bulk of longer telephotos.

As a used lens typically found through specialty dealers like KEH, it appeals to film shooters invested in the GS-1 ecosystem or those building out a Bronica kit for studio and landscape work. The PG lineup is known for solid optical performance and mechanical durability, making used examples viable for ongoing professional and hobbyist use. At this price point, it represents an accessible entry into the GS-1 telephoto range, though availability and condition will vary.
