This outstanding new classic prime lens offers exceptional image performance and unique bokeh. Despite its high speed and impressive imaging quality, its dimensions are astoundingly compact. Together with this lens, every Leica M becomes an extremely compact and elegant photographic tool. The Summicron-M features a rectangular, full-metal lens hood with a screw mount. A screw-in protector ring is provided to protect the filter thread of the lens when the hood is not in use. The eleven blades of the iris of the new Summicron-M 35 mm f/2 ASPH. create a circular aperture. This lends the out of focus areas of subjects a smooth and harmonious look. The newly designed and constructed lens delivers pin-sharp pictures with rich contrast and almost complete freedom from distortion – at all apertures and distances - and even when wide open.
