Bronica 150mm f/3.5 Zenzanon-S Lens for SQ System Review

The Bronica 150mm f/3.5 Zenzanon-S is a medium telephoto lens designed for the Bronica SQ medium format system. With a focal length equivalent to roughly 90mm in full-frame terms, it sits in the classic portrait and detail range for medium format shooters. The f/3.5 maximum aperture is typical for this class of lens, offering a good balance between speed and optical performance. The 67mm filter thread is convenient and widely supported.

This particular listing is a used unit in bargain condition from KEH, priced at $93. Bargain grade typically means visible cosmetic wear but functional optics and mechanics. For photographers already invested in the SQ system or those looking to expand their kit on a budget, this lens offers an affordable entry into the 150mm focal length. However, buyers should expect signs of use and carefully inspect the lens upon arrival. The SQ system remains popular among film shooters who value its modularity and Zeiss-inspired Zenzanon optics.
