Fast multi-coated wide-angle for Bronica ETR 645, 31mm equivalent at f/2.8 with leaf shutter flash sync.
The Bronica Zenzanon 50mm f/2.8 MC is a wide-angle lens for the Bronica ETR 645 medium format system, providing a perspective equivalent to approximately 31mm on 35mm film. The MC designation indicates multi-coating for improved contrast and flare resistance, while the f/2.8 aperture is impressively fast for a medium format wide-angle.
Optically, the lens delivers sharp images with minimal distortion across the 645 frame, benefiting from the multi-coating that reduces ghosting when shooting towards light sources. The 50mm focal length on the 6x4.5cm format provides a useful moderate wide-angle perspective for landscapes, architecture, and environmental portraits.
Build quality follows Bronica's robust standards with all-metal construction and a built-in Seiko leaf shutter for flash synchronisation at all speeds. The focusing ring is smooth with well-spaced distance markings for zone focusing, and the compact dimensions keep the lens manageable on the ETR body.
The Zenzanon 50mm f/2.8 MC offers excellent wide-angle capability for the Bronica ETR system at very competitive used prices. The 645 format provides a good balance between medium format quality and practical considerations like film economy and equipment weight, making this an attractive option for medium format wide-angle work.
