Leica's APO-corrected 35mm for M — the ultimate M-mount wide prime with apochromatic precision.
The Leica APO-Summicron-M 35mm f/2 ASPH. is a premium wide prime for Leica M-mount cameras, combining apochromatic (APO) correction and an aspherical element for high optical performance at 35mm f/2. One of Leica's reference M-system primes. Leica M mount.
f/2 maximum aperture. 35mm focal length. APO (apochromatic correction). ASPH. (aspherical element). Manual focus with rangefinder coupling. At approximately 340g. E39 filter thread. Leica M mount.
The APO correction eliminates the residual chromatic aberration across three wavelengths, producing exceptional colour rendering and micro-contrast at wide apertures. The combination of APO and ASPH. at f/2 represents the highest optical standard in the Leica M 35mm prime range. Regarded as one of the optically best 35mm lenses available for any system.
On the used market the Leica APO-Summicron-M 35mm f/2 ASPH. commands a significant premium even secondhand due to its optical reputation and Leica collectibility. Condition checks: rangefinder coupling cam for wear, E39 front element and APO coatings for marks, focus ring smoothness, aperture blade condition.
