LEICA SUMMARON-M 28 mm f/5.6 ENGINEERING DRAWING LENS SHAPE Illustrations 1:1 This Leica Summaron 28 mm f/5.6 is a replica of the model originally introduced in 1955. With its 6 lens elements arranged strictly symmetrically around the aperture in 4 groups, it has the same optical design. Its extremely compact mechanical construction also corresponds to the original. Unlike this, however, the current model is equipped with the M bayonet including 6 bit code.
