Pairing the classic normal focal length with an optically refined design, the metal gray APO-Summicron-M 50mm f/2 ASPH. Lens from Leica is a fast standard prime characterized by its apochromatic designation. Featuring anomalous partial dispersion and high-refractive-index glass in its design, this lens focuses red, green, and blue wavelengths at the same focal plane, virtually eliminating chromatic aberrations. One aspherical element is also featured in the design to reduce spherical aberrations, and a floating element maintains clarity and sharpness throughout the focusing range from 2.3' to infinity. This compact 50mm lens is also distinguished by its compact form factor, making it ideal for everyday use. Like all M-mount lenses, this 50mm f/2 features a manual focus design and a convenient focusing tab for more refined control during use.
