Ideally suited for landscape and architectural photography, the black Biogon T* 25mm f/2.8 ZM from ZEISS is a versatile wide-angle prime designed for M-mount rangefinder cameras. Its 82° angle of view is complemented by a Biogon optical concept, which nearly eliminates distortion for well-corrected, accurate rendering. 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.
