Leica Summicron-M 50mm f/2.0
The Leica Summicron-M 50mm f/2 stands out due to both its compact and well-proven optical design, as well as its legendary focal length which can provide natural perspectives. Its fine picture quality extends all the way to the extreme corners of the image field, and outstanding contrast is achieved at all apertures.
The well-balanced design makes this ideal standard lens an outstanding choice in terms of all criteria, including image quality, speed, size and weight. Stopping down to f/2.8 or f/4 brings only a minimal increase in contrast. Distortion is extremely low, practically invisible.
