Lens Overview — Leica 11672

The Leica 28mm f/2 Summicron-M ASPH 6-Bit E46 (11672) is a manual-focus wide-angle prime lens built for the Leica M-mount system. Designed to cover the full-frame format, it delivers a maximum aperture of f/2 — a notably fast opening for a 28mm lens — making it well-suited to low-light shooting and situations where some subject separation is desired at wide angles. The lens communicates with compatible Leica M bodies via 6-bit coding, allowing the camera to identify the lens and apply any relevant in-body corrections automatically.

Weighing just 270g, it is a compact and carry-friendly option for photographers who prioritize a lightweight kit without sacrificing aperture speed. Focusing is entirely manual, consistent with the rangefinder shooting philosophy of the Leica M system. The 46mm filter thread (E46) gives access to a wide range of standard filters.

As a prime lens with a fixed 28mm focal length, it encourages deliberate composition and is a natural fit for street, travel, documentary, and environmental portrait work where a wide-angle perspective is preferred. It is compatible exclusively with Leica M-mount cameras.

Key Features — Leica 11672

28mm f/2 Summicron: A maximum aperture of f/2 is unusually fast for a 28mm wide-angle prime, providing meaningful low-light capability and modest subject separation.

Aspherical Optical Design: The ASPH designation indicates at least one aspherical element, reducing spherical aberration and coma for sharper, cleaner rendering across the frame.

Full-Frame Coverage: Designed to cover the full 35mm format, making it a true 28mm wide-angle on all Leica M-series bodies without any crop factor.

6-Bit Lens Coding: Communicates lens identity to compatible Leica M bodies, enabling automatic vignetting and distortion corrections in-camera and in Lightroom.

Leica M Mount: Fits all current and many classic Leica M-mount rangefinder cameras, and is also compatible with mirrorless systems via M-mount adapters.

Manual Focus Only: Fully manual focus operation suits the deliberate, rangefinder-coupled shooting style of the Leica M system.

Description — Leica 11672

The Leica 11672 28mm f/2 Summicron-M ASPH 6-Bit E46 is a full-frame, manual-focus prime lens built around the Leica M mount. Its f/2 maximum aperture makes it one of the faster options in the 28mm wide-angle range, offering useful light-gathering capability for available-light photography. At 270g, the lens keeps your kit compact and balanced — an important consideration for rangefinder shooters who value discretion and mobility in the field.

The 6-bit encoding communicates lens identity to compatible Leica M bodies, supporting any automatic correction or metadata logging the body offers. A 46mm filter thread (E46) provides access to a broad selection of screw-in filters. With a fixed 28mm focal length and manual focus only, this lens rewards a considered, intentional approach to shooting, making it a natural choice for street, travel, and documentary photographers working within the Leica M ecosystem.
