The nominal focal lengths of the Leica SL lenses are based on the 35mm-format, i.e. on a film format of 24 x 36mm. In

comparison, with its 15.7 x 23.6mm, the sensor in the
(approximately by a factor of 0.66). Therefore, when used on the Leica
view corresponding to lenses with focal lengths that are longer by a factor of 1.53 (1.53 = reciprocal of 0.66).
The MTF (see Annex) is stated for full aperture and for the apertures 2,8 and 5.6 for large shooting distances (infinite). The
contrast is applied in percent for 5, 10, 20, 40 Lp/mm over the height of the format for tangential (dotted line) and sagittal
structures (solid line) in white light. 5 and 10 Lp/mm give an impression of the contrast behavior for coarser object
structures, 20 and 40 Lp/mm document the resolving power of fine and the finest object structures.
