The Biogon T* 2,8/25 ZM delivers high contrast across the entire image field and is virtually free of distortion at full apertures. With the aperture stopped down, detail is finely rendered with a pleasing three-dimensional quality. The lens is rangefinder-coupled for easy focusing and the optional 25/28 mm viewfinder is available for accurate image composition. Combined with a digital rangefinder camera with a 1.3 crop factor, the lens has an effective focal length of 33 mm. The Biogon T* 2,8/25 ZM is a creative tool for scenic portraits, inspiring landscapes and expansive architectural photography

Why M-mount?

For more than 50 years now, passionate 35 mm photographers have been embracing the M-mount rangefinder camera system. From the lens designer's perspective, a rangefinder camera offers an exciting advantage over single lens reflex (SLR) cameras: more space. After all, there is no moving reflex mirror and drive mechanism. This allows for a short distance between the last lens element and the film meaning more opportunities for designing of superior lens types, including high performing wide-angle lenses.

A passion ready for the challenge

For our lens designers, the chance to develop the Carl Zeiss family of T* ZM-mount lenses was a dream come true. They were free to follow their passion in pursuit of perfection in lens performance, taking full advantage of our uncompromising symmetric lens designs. The only limitation was to reserve 15 mm in front of the film for the TTL exposure metering, commonplace in M-mount cameras. The result is a complete range of the most advanced M-mount lenses ever made.

Superior in every way

The Carl Zeiss range of T* ZM-mount lenses offers the highest possible standards in terms of performance, reliability and, of course, image quality. Quite simply, they are superior in every way. You can count on highly advanced flare control for crisp and brilliant images, for example. And virtually zero geometric distortion, ensuring precise accuracy when reproducing shapes - especially useful when photographing products and architecture.

Carl Zeiss T* ZM-mount lenses are specifically designed to minimize focus shift with aperture changes - an important innovation with big benefits for rangefinder photography. As a result, you can expect improved accuracy of the rangefinder-defined focus. While the precise 10-blade aperture with 1/3 stop interval click stops ensures exact exposure. For reliable performance, Carl Zeiss T* ZM-mount lenses are designed with a wear resistant filter mount and an extremely accurate rangefinder coupling mechanism.

  • Virtually zero geometric distortion for accurate reproduction of object shapes, particularly products and architecture
