Lens OverviewBronica 150mm f/3.5

The Bronica SQ 150mm f/3.5 Zenzanon-S is a manual focus prime lens built for the Bronica SQ medium format camera system. As a telephoto prime with a fixed focal length of 150mm, it sits comfortably in portrait and short telephoto territory for medium format shooters. The lens features a maximum aperture of f/3.5, providing meaningful light-gathering capability and the ability to manage depth of field for subject isolation.

Designed exclusively for the Bronica SQ mount, it integrates natively with compatible SQ-series bodies without adapters or compromises. The lens accepts 67mm filters, a practical and widely available thread size that makes it easy to pair with polarizers, ND filters, or other glass. Weighing in at 600g, it carries a solid, substantive feel consistent with medium format optics.

Image stabilization is not present, which is expected for a manual focus medium format prime of this era — steady technique or a tripod is recommended, particularly at longer exposures. For photographers already invested in the Bronica SQ ecosystem, this 150mm Zenzanon-S lens represents a dedicated telephoto option that keeps shooting entirely within a proven, purpose-built system.
