See pictures for details Carl Zeiss says this about their 50mm f/1.4 Planar lens: This bright and compact standard lens has a precise manual focusing mechanism and large rotation angle for precise control. The Planar T* 1,4/50 is designed for medium and longer distances and provides high-performance wide open, which only improves as the lens is stopped down. The lens construction controls flare and ghosting artifacts, resulting in a brilliant image with excellent contrast and natural color rendition. The lens comes with front and rear caps, a Contax G-11 rubber hood and a A1 skylight filter to protect the front glass (which I never take off). This lens not only looks beautiful, it has a very satisfying weight and "feels" great in your hand. The manufacturing quality is excellent, you could not wish for a better lens. The focus ring turns with just the right level of resistance and the appature stops are crisp and positive which adds to the sensation of high-end quality. It is virtually impossible to spot any kind of spherical, chromatic or geometrical aberration unless you examine the lens under lab conditions. This lens delivers a rare feeling of quality that you just don't get now days with most lens manufacturers. Every mechanical part offers a smooth and velvety as well as secure impression. Legend claims that this lens is one of the, if not "the" #1 highest resolving 35 mm format lens. This lens is also a perfect match for full frame digital cameras (Canon, Nikon) when used with the appropriate adapters (not included).
