Bronica 250mm f5.6 MC (1976)
A medium-format manual focus telephoto prime lens introduced with the Bronica ETR system.
Overview
The Bronica 250mm f5.6 MC is a manual focus telephoto prime for the Bronica ETR series of 6x4.5 medium format SLR cameras. It came out in 1976 as part of the first generation of Zenzanon lenses, the first optics Zenza Bronica made itself under the Zenzanon brand. It was sold as a professional-grade lens. The multi-coating (MC) cuts flare, and the long focal length isolates the subject against a blurred background.

Design
The optics are multi-coated (MC), with PE coatings meant to reduce internal flare. The lens was part of the initial Zenzanon lineup for the ETR system. Before this, Bronica had relied on Nikon for its optics.
Context
The lens was introduced in 1976 alongside the Bronica ETR camera. Nikon had stopped making lenses for Bronica, so the company built its own optical line under the Zenzanon name. This one was the dedicated telephoto option for professional medium format photographers on the 6x4.5 system.
