A classic wide-angle prime for M-mount rangefinders, the black Biogon T* 28mm f/2.8 ZM from ZEISS is a versatile lens well-suited to travel, landscape, and other documentary applications. Its Biogon optical design effectively eliminates distortion for well-corrected imagery and one anomalous partial dispersion element is used to reduce chromatic aberrations and color fringing for notable clarity. A T* anti-reflective coating has also been applied to individual elements to reduce lens flare and ghosting for greater color accuracy and contrast in strong lighting conditions. Additionally, the lens's manual focus design permits working with subjects as close as 1.6' away.
