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.

期待实拍。。。
