{{ :lens:35mmf2summicron-rii.png?250|}}
==== Summary ====
The Leica Summicron-R 35mm f/2(II) is a fast wide-angle prime lens for 35 mm SLR Leica R cameras. The lens is remarkable for minimum vignetting, almost full absence of distortion, and excellent anti-glare protection. Thanks to a larger than standard diagonal angle of view (64°), it is perfectly suitable for found photography. The lens is compact, lightweight, and convenient. This is the 2nd version of the Leica Summicron 35mm f/2 (Series 7).
