The angle of view of the Leica Elmarit-S 45 mm f/2.8 ASPH (CS) corresponds to that of the classic 35mm focal length for 35mm photography and, with its moderate wide-angle coverage and true-to-life perspectives, is outstanding for landscapes and architectural photography as well as for studio work.
Two others of high-refractive-index glass with exceptionally low dispersion
In addition to these, one aspherical surface is employed for the minimization of monochromatic aberrations
Reargroup focusing guarantees consistently outstanding imaging performance from infinity to the closest focusing distance
Three of the twelve lens elements are manufactured using specialized glass with anomalous partial dispersion that minimizes chromatic aberration
