Bronica 135mm f/4 Zenzanon-PE Lens for ETR System Review

The Bronica 135mm f/4 Zenzanon-PE is a medium-telephoto prime lens designed for the Bronica ETR system, a medium format film platform popular among portrait and commercial photographers. With its 135mm focal length on the ETR's 645 format, it delivers a field of view similar to roughly 85mm on full-frame 35mm cameras, making it well-suited for portraiture and selective subject isolation. The f/4 maximum aperture is typical for medium format glass of this era, offering a practical balance between speed and optical performance. This used example from KEH arrives in excellent condition with front and rear caps included. At $224, it represents an affordable entry point into medium format telephoto work for those already invested in the ETR system or looking to expand their vintage lens collection.
