LEICA M11 Monochrom Rangefinder Camera - Manual (Page 38)

PREPARATION ▸ LENS 38
LENS DETECTION
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. image data optimization. Edge
darkening, for example, which can become noticeable when
wide-angle lenses and large apertures are used, is compensated
in the relevant image data.
– The information provided by the 6-bit encoding is also written to
the Exif data. The focal length of the lens is additionally displayed
when rendering the extended image data.
– The camera will write an approximate aperture value to the Exif
image data, which is calculated individually using the exposure
metering system. This is done whether or not an encoded or unen-
coded lens or a non-M lens is attached via adapter, and regard-
less 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 Auto automatically when an
encoded Leica M lens is attached, regardless of the original lens
setting.
USING A LEICA M LENS WITHOUT 6-BIT ENCODING
The lens type must be entered manually when using a Leica M lens
without 6-bit encoding.
