First aspherical Leica Summicron 35mm, dramatic wide-open improvement over pre-ASPH at luxury pricing.
The Leica Summicron-M 35mm f/2 ASPH Version 1 is the original ASPH design of the Summicron-M 35mm — a 7-element formula produced approximately 1997-2012. Leica M mount.
35mm focal length. f/2 maximum aperture. ASPH element. 7-element optical formula. Manual focus. Version 1 design. Leica M mount.
The Summicron-M 35mm ASPH v1 is the original ASPH design — compact, sharp wide open, with the ASPH element correcting distortion. The Version 2 (current, 8-element) improved on corner sharpness; the v1 remains excellent. Distinguished from the non-ASPH versions (Types I-IV) by the floating element for close-focus. One of the most desirable Leica M lenses.
On the used market the Summicron-M 35mm ASPH v1 is a highly sought-after wide prime. Condition checks: ASPH element, f/2 quality wide open, focus accuracy. Leica M mount.
