Lens Overview — Bronica 150mm f/4

The Bronica 150mm f/4 Zenzanon MC is a manual focus prime lens built for the Bronica SQ medium format camera system. With a fixed focal length of 150mm and a maximum aperture of f/4, this telephoto prime sits comfortably in portrait and short telephoto territory for medium format shooters. The lens is constructed for the Bronica SQ mount, making it a dedicated fit for that specific system without the need for adapters or workarounds.

Weighing in at 780g, it carries the expected heft of a medium format optic, though it remains a manageable option for handheld or studio use. The filter thread measures 67mm, a common size that opens up a wide range of compatible filter options for landscape, portrait, or specialty work. Focus is entirely manual, which suits the deliberate, methodical shooting style that medium format photography typically demands.

Image stabilization is not present, consistent with the optical design conventions of lenses in this class and era. For photographers working with Bronica SQ bodies and seeking a dedicated 150mm telephoto prime, the Zenzanon MC represents a well-specified option with clear mounting compatibility and a solid physical build.

Key Features — Bronica 150mm f/4

150mm Medium Format Prime: Equivalent to a short telephoto on 35mm, making it well-suited for portraits, still life, and close editorial work on medium format bodies.

Bronica SQ Mount: Designed exclusively for Bronica SQ-series bodies, providing native mechanical compatibility without adapters.

f/4 Maximum Aperture: Offers workable light gathering and moderate background separation for a medium format telephoto prime of this era.

Multi-Coated Optics: The MC designation indicates multi-coated lens elements, reducing flare and ghosting compared to earlier single-coated Zenzanon designs.

Manual Focus Design: Fully manual focus operation suits the deliberate, controlled shooting workflow typical of medium format photography.

67mm Filter Thread: Standard filter size gives access to a wide range of readily available filters for portrait, landscape, or specialty use.
