Never hold the combination of a T camera and this lens just by the camera housing; always support the lens as well. This

relieves pressure on the camera bayonet fitting.
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
2
comparison, with its 23.6 x 15.7mm, the sensor in the LEICA T (type 701) is somewhat smaller though, approximately by a
factor of 0.66. Therefore, when used on the LEICA T (type 701), these lenses have angles of view corresponding to lenses
with focal lengths that are longer approximately by a factor of 1.52 (1.52 = reciprocal of 0.66).
3 Function is not available when used on the Leica T (Type701).
4 Function is slower when used on the Leica T (Type701).
The MTF (see Annex) is stated for full aperture and for the apertures 5,6 and 8 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.
