Descripción

Most optical design departments in the world use the software program Code-V for design and optimization. The program is very powerful, but the optimization algorithms tend to favor the average taste. Most lenses by the major lens manufacturers are based on Code-V and while most of them are capable of good imagery, they lack personality. David Shafer has written numerous articles in which he draws attention to the fact that lens design starts in the mind and the computer should follow,not dictate. One lens that clearly shows the mind-above-computer-approach is the Elmarit-M 2.8/24mm ASPH.

This lens is without any doubt a masterpiece of optical engineering and within the Leica M range a landmark design. It is a matter of personal priorities which aperture is the optimum: 1:4 is for all intents and purposes best. A wide-angle lens like a 24mm is less usable if the close up performance would not equal the infinity setting. Flare suppression is perfect. This suppression of halo and flare gives the pictures taken with the Elmarit-M 1:2.8/24mm ASPH its very realistic, almost tactile rendition. Vignetting is about 2 stops and distortion is hardly observable. Pictures taken with this lens have outstanding definition of fine detail in the foreground, with an added sparkle and clarity for pictures of scenes with high luminosity.
