LENS DETECTION

EN
The 6-bit encoding in the bayonet of current model Leica M lenses
allows the camera to detect the lens type.
– This information is used for e.g. picture data optimization. Edge
darkening, for example, which can become noticeable when
wide-angle lenses and large apertures are used, is compensated
in the relevant picture data.
– The information provided by the 6-bit encoding is also written to
the EXIF data of the pictures. The focal length of the lens is
additionally displayed when rendering the extended picture data.
– The camera will write an approximate exposure value to the EXIF
picture data, which is calculated individually using the exposure
metering system. This is done whether or not an encoded or
unencoded lens or a non-M lens is attached via adapter, and
regardless of whether the lens type was entered in the menu.

USING A LEICA M LENS WITH 6-BIT ENCODING

The camera will automatically set the correct lens type when a
Leica M lens with 6-bit encoding is used. No manual setting will be
required. The camera will switch to
encoded Leica M lens is attached, regardless of the original lens
setting.

USING A LEICA M LENS WITHOUT 6-BIT ENCODING

A standard profi le will be used if a Leica M lens without 6-bit
encoding is attached. No lens data will be saved to the EXIF data.
