LENS DETECTION

The 6-bit coding in the bayonet fastening of current Leica M lenses
allows the camera to identify the type of lens fitted using the
sensor in the bayonet socket.
– Among other things, this information is used to optimize the
picture data. Thus edge darkening which can be noticeable with
wide-angle lenses and large apertures can be compensated in
the corresponding picture data.
– Flash exposure and reflector control also use the lens data (see
"Compatible flash units", p. 192).
– In addition, the information provided by this 6-bit coding is
written to the EXIF data for the picture. When displaying
extended image data, the lens focal length is also shown (see p.
247).
