Bronica 150mm f/3.5 Zenzanon MC Lens for ETR System Review

The Bronica 150mm f/3.5 Zenzanon MC is a medium telephoto lens designed for the Bronica ETR medium format system. With its 62mm filter thread and f/3.5 maximum aperture, it delivers a focal length equivalent to roughly 90mm in full-frame terms, making it a practical choice for portraiture, product work, and selective framing in medium format. The Zenzanon MC (multi-coated) optics are known for their sharpness and color rendition, typical of mid-range Bronica glass from this era.

This particular unit is offered by KEH in bargain condition, meaning visible cosmetic wear and possible functional issues such as cleaning marks or stiff focus rings. At $86, it sits at the entry point for ETR system lenses, well below market rates for good or excellent examples. For shooters willing to accept cosmetic imperfections and potential optical compromises, it's an affordable way to expand focal length options on the ETR platform. However, buyers should be prepared for the possibility of haze, dust, or mechanical quirks common in bargain-grade vintage lenses.
