Descripción

Some lenses are at first glance extremely sympathetic and the Summarit-M 1:2/75 mm is one of these rare designs. It has a beautiful compact mount with rubberized grip and very smooth operation. In addition it offers a performance that only a shade below that of the companion lens, the Apo-Summicron-M 1:2/75mm ASPH. The Summarit can be characterized as a high-contrast-high-definition lens with excellent resolving power of fine detail. At maximum aperture there is a faint softening of main subject outlines, but at medium apertures the lens performs admirably well.

The color transmission of the Summarit is close to neutral with a slight warm bias. Color transmission is less important now with the digital workflow where the white balance options can correct the color bias. The Summarit lens fits in the classical tradition of the Leitz designers that goes back to the days of Berek: high performance in a small package that suits the rangefinder philosophy of unobtrusive picture taking with pocket sized cameras and lenses.
