• Please note the following when using the rangefinder of a Leica M for
focusing:
– Leica M lenses are fitted with a control curve that mechanically transfers
the set distance to the camera, thus enabling manual focusing with the
viewfinder of the Leica M camera.
– The focusing mechanism of every camera and every lens is adjusted
individually in the Leica Camera AG factory in Wetzlar with the greatest
possible precision. Extremely narrow tolerances are adhered to in this
process, which enable precise focusing of every camera/lens combination
in photographic practice.
– Bright lenses like this have an extremely shallow depth of field when the
aperture is open. Together with inaccuracies in focusing using the
rangefinder and the (added) overall tolerance of the camera and lens, there
may therefore be setting errors. When viewed critically, it therefore cannot
be ruled out that a certain camera/lens combination manifests systematic
deviations.
– If such a general deviation of the position of the focusing level in a certain
direction can be seen, it is recommended that the camera and lens be
checked by the Leica Camera AG Customer Care department (Address, see.
p. 27). The staff there can once again check whether the two products are
adjusted within the permitted overall tolerance. Please understand that a
100 % match of the focusing level position cannot be achieved for all
camera/lens pairings.
