Leica designed a number of f/2 lenses before the Summicron, such as the Summar and Summitar. New coating technologies available after World War II allowed for the creation of the Summicron lens. The first Summicron was an evolved Summitar collapsible 50mm with Lanthanum glass, and was launched in 1953. [ 2 ]
The name Summilux is a combination of Summum, which is the Latin word for highest, while Lux is for light. [1] The first Summilux was the 50 mm of 1959, followed by a new 50 mm Summilux design in 1961, whose optics remained unchanged until replaced by the 50 mm Summilux-M ASPH of 2004.
M-Rokkor 28mm F2.8. This lens is not the same as any of the Leica M 28mm F2.8's, being a 7 element, 5 group design [26] while contemporary Leicas were 8e/6g (Elmarit II '72–'79 and Elmarit-M III '79–'93). The M-Rokkor was sold for about less than half the price – however Modern Photography tests indicated that performance was as good as ...
While in principle aspheric surfaces can take a wide variety of forms, aspheric lenses are often designed with surfaces of the form = (+ (+)) + + +, [3]where the optic axis is presumed to lie in the z direction, and () is the sag—the z-component of the displacement of the surface from the vertex, at distance from the axis.

Among scopes for rail mounts, the 22.5-degree V-shaped Zeiss rail is the most prevalent standard. It was introduced in 1990. After the patent expired in 2008, compatible scopes have been offered from manufacturers such as Blaser, [1] Leica, Minox, Meopta, Nikon, [2] Noblex (formerly Docter [3]), Schmidt & Bender [4] and Steiner.
