Leica Summicron-M 28mm f/2 ASPH.
Compact and versatile
Exceptional - in every respect
This new wide-angle lens is fast, compact and delivers exceptional performance. Its outstanding speed makes it particularly versatile and delivers brilliant imaging results even in difficult lighting conditions. Its full-metal lens hood with a screw mount protects the optical system against undesirable stray light and flare. A screw-in protector ring is provided with the lens to protect the filter thread of the lens when the hood is not in use.
Technical details
At its maximum aperture, the Summicron-M 28 mm f/2 ASPH. already delivers impressively rich contrast, differentiated reproduction of even the finest structures, a soft and smooth bokeh and extremely high resolution. This is due to its recalculated optical design, which almost completely eliminates the astigmatic differences in the image field caused by the cover glass of the sensor to ensure excellent image quality from corner to corner in every picture.
