This classic, wide-angle focal length with a moderate perspective complements the standard 50 mm focal length. The Biogon T* 2,8/28 ZM exhibits crisp detail without distortion at full apertures, even at the close-focus range. The optical construction minimizes flare, enabling photography against a strong back light 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. Combined with a digital rangefinder camera with a 1.3 crop factor, the lens has an effective focal length of 36 mm ideal for reportage style photography. 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.
