Description — Zeiss 25mm f/2.8 ZM
The ZEISS Biogon 25mm f/2.8 is a manual-focus, wide-angle prime lens built specifically for the Leica M mount. With a 25mm fixed focal length and a maximum aperture of f/2.8, it offers a dedicated wide-angle perspective suited to landscape, architectural, and street photography. Designed for full-frame coverage, it performs across the entire 35mm sensor area.
The lens accepts 46mm filters, keeping the front element compact and the accessory footprint manageable. At just 260g, it is light enough to carry all day without fatigue, complementing the slim profile of M-mount rangefinder cameras. Focus is entirely manual, placing the shooting experience firmly in the photographer's hands — an approach well-matched to the deliberate, frame-by-frame style that this camera system is known for.
There is no image stabilization, so technique and ambient light conditions play an important role in exposure decisions. Overall, this is a compact, lightweight, and capable wide-angle prime for photographers committed to the Leica M system.
