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 first aspherical version of the definitive M-mount wide-angle, dramatically improving wide-open sharpness over the earlier non-ASPH Summicron 35mm variants. The ASPH V1 brought modern optical performance to the most important M focal length.
The aspherical element provides significantly improved wide-open sharpness compared to pre-ASPH versions while maintaining the Summicron f/2 balance of speed and compactness. The rendering combines modern sharpness with subtle Summicron character that later versions refined further.
Build quality is Leica M with machined brass. The ASPH V1 represents the first major optical upgrade in the 35mm Summicron lineage, and the specific V1 designation distinguishes it from the current production version.
The Summicron-M 35mm f/2 ASPH V1 holds strong value as the first aspherical version of Leica's most important wide-angle. The ASPH improvement was dramatic, and the V1 provides significantly better wide-open performance than any pre-ASPH variant.
