Description — Zeiss 28mm f/2.8 ZM
The Zeiss Biogon T* 28mm f/2.8 is a manual-focus prime lens designed for full-frame Leica M-mount rangefinder cameras. With a fixed 28mm focal length and a maximum aperture of f/2.8, it covers the wide-angle range and offers a solid balance between field of view and light transmission. There is no autofocus and no image stabilization, keeping the optical design focused on the fundamentals of wide-angle prime performance.
The lens accepts 46mm filters — a modest size that reflects the compact physical footprint — and tips the scales at just 230g, making it one of the lighter options for full-frame wide-angle shooting. It integrates with the Leica M system via the Leica M mount and features a Leica M hot shoe. For rangefinder photographers who prefer working with a fixed wide-angle perspective and manual focus discipline, this lens offers a straightforward, well-matched specification set for the Leica M ecosystem.
