Digital Camera World Verdict

The Leica 50mm APO Summicron-M f/2 ASPH is one of Leica’s most popular lenses in its APO line-up. Its characteristics are legendary for producing exceptional sharpness, even wide-open to its full control of the Red, Blue, and Green waveform to produce lifelike images with a distinct pop that only a Leica lens can produce. This 50mm is a super lens to use, and featuring a maximum aperture of f/2 makes this the perfect partner for those who love to separate their subjects from the background or achieve outstanding images in low-light conditions.
