The name Summicron is used by Leica to designate camera lenses that have a maximum aperture of f/2 after 1953 and to present day.
The name Summicron is derived from summus, latin word for maximum and kronos, the ancient Greek word for time. In the 1950s Leica bought Crown glass from Chance Brothers, an English company and used it to make the lenses. [1]
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] Generations before approximately 1960 were produced in M39 mount ("screw mount"), then made available in M-mount (Latch-on A42), R-mount, and C-mount. [2]
Faster Leica lenses are offered with the trade names Noctilux (or Nocticron) and Summilux. Summarit, Elmarit, and Elmar lenses are slower.

Macro photography is extreme close-up photography, usually of very small subjects and living organisms like insects, in which the size of the subject in the photograph is greater than life size . By the original definition, a macro photograph is one in which the size of the subject on the negative or image sensor is life size or greater. In some senses, however, it refers to a finished photograph of a subject that is greater than life size.
The Leica M3 is a 35 mm rangefinder camera by Ernst Leitz GmbH, introduced in 1954.

The M3 introduced several features to the Leica, among them the combination of viewfinder and rangefinder in one bright window, like on the Contax II, a bayonet lens mount, and rapid film advance lever. It was the most successful model of the M series, with over 220,000 units sold by the time production of the M3 model ended in 1966.
