Leica 50mm f/2 Summicron-M M Mount Lens, Black (11819), 6 Bit Coded {39} Description


The Leica 50mm f/2 Summicron-M (11819) is a renowned standard lens for the M-mount system.  It's a great general purpose lens that produces a normal field of view with the beautiful image quality Leica is famous for.

The double gausss lens design uses 6 elements in 4 groups that have been single-coated, as well as eight aperture blades.  The Leica 50mm f/2 Summicron is an excellent lens producing outstanding sharpness, bokeh, and accurate color rendition.  Even wide-open with narrow depth-of-field, no coma can be discerned in the image area and the Summicron 50mm produces high-quality contrast, distortion-free, sharp photos with minimal vignetting or ghosting.  It's ability to work in poor or dimly lit environments lets you creates smooth images without having to increase digital noise through higher ISO values.

The 50 Summicron-M has a solid durable all metal design. The aperture ring clicks from f/2-16 in ½ stop increments.  Originally introduced in 1979, the 11819 version performs so remarkably well that Leica kept the same optical design when replacing it in 1994 with the 11826 which features a built-in lens hood; with the same effective optics the 11819 has remained quite popular.  This particular Summicron-M (11819) has also been 6-Bit coded to allow digital M cameras to automatically identify the lens as soon as it's mounted for adjustments based on it's unique optical characteristics and for EXIF information.  It's a very pleasant lens to carry and use, perfect for street, landscape, portraits, indoor scenes and so much more.  A classic lens that performs very well, the Leica 50mm f/2 Summicron-M is a great compliment to any Leica M body.
