Description — Zeiss 50mm f/1.5 ZM
The ZEISS Sonnar T* 50mm f/1.5 ZM is a manual focus prime lens designed exclusively for the Leica M mount rangefinder system. With a maximum aperture of f/1.5, it offers strong light-gathering capability well-suited to low-light and available-light shooting scenarios. The 50mm focal length falls within the standard range, providing a natural field of view that works across portrait, street, and documentary styles of photography.
Covering the full-frame format, this lens is compatible with the full range of Leica M mount bodies — both film and digital — without any cropping concerns. The 46mm filter thread keeps accessory costs accessible, while the 340g weight strikes a practical balance between build solidity and portability on a rangefinder body. There is no image stabilization, and focus is handled entirely manually through the rangefinder's coupled focus mechanism.
The ZM designation confirms its Leica M mount compatibility, and the Prime classification means there is no zoom — just a single, fixed focal length built for deliberate, precise image-making.
