The APO-Macro-Summarit-S 120 f/2.5 (CS) (96 mm in 35 mm format) has a true dual function. Firstly, it is a macro lens for closeup photography up to a reproduction ratio of 1:2, and secondly, it is a fast telephoto lens with an unusually wide maximum aperture of f/2.5.

At the same time, it offers such astounding imaging qualities at maximum aperture throughout its entire focusing range that stopping down really only increases the depth of field but cannot further increase its superior contrast rendition. This brings countless fascinating options for exploring the creative opportunities offered by selective sharpness. The alternative CS version with a central shutter further increases its enormous range of potential uses.
