Description — Zeiss C Biogon T* 35mm f/2.8 ZM
The ZEISS C Biogon T* 35mm f/2.8 ZM is a manual-focus, prime wide-angle lens built specifically for the Leica M mount. Covering a full-frame image circle at a fixed 35mm focal length and a maximum aperture of f/2.8, it delivers a classic wide perspective well suited to street, travel, and documentary shooting. At just 200g, it is one of the lighter options available for M-mount photographers, and its compact build aligns with the 'C' designation that defines this line.
The 43mm filter thread is worth noting when building a filter system, as this diameter is not as widely stocked as more common sizes. There is no image stabilization, so a steady hand or appropriate exposure settings are necessary. The lens operates entirely in the mirrorless/rangefinder camera ecosystem via the Leica M mount, making it a focused, no-frills wide-angle prime for photographers who shoot deliberately and value a light, unobtrusive kit.
