Description — Leica 28mm f/2 ASPH
The Leica Summicron-M 28mm f/2 ASPH is a full-frame prime lens built specifically for the Leica M mount rangefinder system. It offers a 28mm fixed focal length with a maximum aperture of f/2, delivering solid low-light performance for a wide-angle optic. Weighing just 230g, it is an impressively lightweight lens that keeps your kit nimble and travel-ready.
The 46mm filter thread is compact and cost-effective for those who use polarizers or ND filters. Focus is entirely manual, consistent with the tactile, deliberate nature of rangefinder photography. With no image stabilization and no autofocus, this lens asks the photographer to slow down and engage fully with the shooting process — a quality that many M-mount users actively seek.
Its full-frame format coverage makes it a natural fit for the standard Leica M digital and film bodies, delivering an uncompromised 28mm field of view across the entire sensor or film frame.

- ✗46mm filter thread, while compact, is a less common size that may require dedicated step-up rings to match existing filter sets
