LEICA M LENSES
Most Leica M lenses can be used with any lens equipment (with or
without 6-bit encoding in the bayonet). Your camera will also deliver
great photographs when using Leica M lenses without encoding. We
recommend entering the lens model type manually to ensure the
best possible image quality (see p. 38).
Please read the following sections for details on the very few excep-
tions and limitations.
Notes
• Our Leica Customer Care department can retrofit many Leica M
lenses with 6-bit encoding.
• Leica M lenses come with a control curve that mechanically trans-
fers the set distance to the camera to allow manual focusing via
the rangefinder of the Leica M camera. Please note the following
when using the rangefinder with wide-aperture lenses (≤ 1.4):
– The focusing mechanism of every camera and every lens is
adjusted individually at the Leica Camera AG factory in Wet-
zlar with the greatest possible precision. Extremely narrow
tolerances are adhered to in this process, which allow precise
focusing of every camera/lens combination in photography.
– If wide-aperture lenses (≤ 1.4) are used with an open aperture,
the then sometimes resulting very low depth of field, and inac-
curacies in focusing with the rangefinder may lead to setting
errors resulting from the (added) overall tolerance of the cam-
era and lens. It can therefore not be ruled out that a specific
camera/lens combination may result in systematic deviations.
– We recommend having the lens and camera checked by Leica
Customer Care if you notice a general deviation of the focal
position in a specific direction over time. Our technicians will
ensure that both products are calibrated within the permissible
overall tolerance. However, a 100% match of the focal position
cannot be achieved for all pairings of cameras and lenses.
LEICA R LENSES (WITH ADAPTER)
The optional accessory Leica R-Adapter M allows the use of Leica R
lenses as well as Leica M lenses. Please visit the Leica Camera AG
website for more information on this accessory.
