24MM BAYONET MOUNT LENSES

It is important to note that Leica lenses had their focal lengths specified in millimeters from 1925 to 1928, in centimeters from 1928 to 1970, and again in millimeters from 1971 onwards³⁶⁰.

24mm f/2.8 Elmarit-M ASPH

Introduced at Photokina in 1996, 24mm f/2.8 Elmarit-M ASPH lens features the molded aspherical lens technology. It consists of seven elements arranged in five groups, including one aspherical surface, one element made of special glass with partial anomalous dispersion, and two additional elements crafted from highly refractive glass. The lens has a length of 45mm from the bayonet flange, weighs 290 grams, and has a filter size of E55. Its smallest aperture is f/16. A separate bright-line viewfinder is also available for use with this lens²⁰⁴.
The 24mm f/2.8 Elmarit-M ASPH is the first 24mm wide-angle lens designed for the M system and sets new performance standards in this focal length category, which photographers often prefer for dynamic shots in tight spaces. It provides an angle of view of 84 degrees and is compact, weighing only 290 grams, making it ideal for achieving exceptional depth of field. This new lens utilizes an aspherical glass surface, an element made of anomalous partial dispersion glass, and two additional highly refractive elements to ensure high contrast and detail at full aperture. At full aperture, coma, field curvature, and astigmatism are virtually eliminated, thanks to its seven-element, five-group design. This high level of performance is consistently maintained throughout the entire focusing range, down to a minimum focus distance of 0.7 meters. A separate, non-parallax-corrected optical viewfinder is available for composition and can be mounted in the camera accessory shoe²¹⁵.
As of 1998, this lens is available in a silver chrome finish, with a price of 2295 USD²¹⁵.
