The Leica 50mm f/1.4 ASPH Summilux-SL is a fast, L-mount prime lens optimized for the Leica SL – Typ 601. Key features include
Fast Aperture Normal Angle Lens
High Quality Optics
Normal Angle. When used on a full-frame camera, the 50mm focal length offers a normal field of view that’s useful for just about any type of photography. With an APS-C sensor camera, you’ll have a portrait-range focal length of about 75mm. The fast f/1.4 aperture offers both great low-light performance and shallow depth-of-field control.
High Quality Optics. The lens features 11 elements in 9 groups, including two aspherical and four anomalous partial dispersion elements that cut down on aberrations, while keeping pictures sharp and clear. A multi-layer coating minimizes the effects of flaring and ghosting.
Solid Build. This über nifty fifty is built like a tank. Its weather-sealing keeps out dust and moisture. An internal focusing system doesn’t rotate the front filter ring, which makes the lens fully capable of working with circular polarizers, graduated ND Filters, and variable ND Filters.
