Standard lenses from Leica are small and lightweight lenses with high performance. They combine high speed with outstanding imaging capabilities. And they are especially versatile, because their angle of view 45° comes closest to the visual coverage of the human eye.The 50 mm f/2 SUMMICRON-R is a universal lens with outstanding imaging quality, even in the near-focusing range. Ideally suited for travel photography, because its 41 mm length (1 5/8") and 300-gram weight (10 1/2 ounces) make it unusually compact and handy. The shortest focusing distance is 50 cm or 1' 7 3/4 ". In spite of its high speed, it distinguishes itself by its outstanding sharpness, high contrast and excellent detail resolution, even at full aperture.
