Take the road less travelled.

The optical construction minimizes flare, enabling photography against a strong backlight without compromising image quality. This lens has the widest angle of view that can be used with the integrated viewfinder on the Zeiss Ikon rangefinder camera, an additional 25/28 mm viewfinder is available. The Biogon T* 2,8/28 ZM is ideal for travel photography and is also well-suited for group and interior photographs when space is at a premium and wide-angle distortion needs to be minimized.
