Lens Overview — Leica 11626
Key Features — Leica 11626
Three Fixed Focal Lengths: Clicks between 16mm, 18mm, and 21mm positions, giving shooters three distinct ultra wide-angle perspectives in a single lens without carrying multiple primes.
Leica M Mount: Native M-mount fit ensures direct, adapter-free compatibility with Leica M rangefinder bodies including the M10, M11, and earlier film M cameras.
Aspherical Optical Design: ASPH-designated elements reduce spherical aberration and distortion across all three focal lengths, supporting edge-to-edge sharpness on full-frame sensors.
Full-Frame Coverage: Designed to cover the full 35mm full-frame image circle, making it fully usable on all current and legacy Leica M bodies.
Constant f/4 Aperture: Maximum aperture remains f/4 at all three focal length positions, providing consistent exposure settings when switching between focal lengths.
Manual Focus Only: Smooth manual focus ring designed to integrate with the rangefinder focusing discipline of the Leica M system.

Description — Leica 11626
The Leica Tri-Elmar-M 16-18-21mm f/4 ASPH is a manual-focus, Leica M mount ultra wide-angle zoom lens designed for full-frame coverage. It spans a focal length range from 16mm to 21mm, with three selectable focal length positions that give photographers meaningful compositional flexibility in a single lens unit. The maximum aperture of f/4 remains consistent across the zoom range, providing predictable exposure control at every focal length setting.
Weighing just 335g, the lens strikes a practical balance between optical range and portability for M-system shooters. A 67mm filter thread allows straightforward use of standard photographic filters. The lens carries no image stabilization and is exclusively manual focus, both of which are characteristic of the Leica M rangefinder lens family.
Classified as an ultra wide-angle zoom in the wide-angle focal length range, this lens is well-suited to landscape, architecture, and travel photographers working within the Leica M ecosystem who prioritize having multiple wide perspectives available without carrying separate prime lenses.
