The following can be used with restrictions
Despite the high precision of the range finder on the camera, exact
focusing with 135mm lenses with an open aperture cannot be
guaranteed due to the very low depth of field. Therefore, stopping
down by at least 2 stops is recommended.
• Possible, but excluded from the exposure metering
– Super-Angulon-M 1:4/21mm
– Super-Angulon-M 1:3,4/21mm

Notes:
• The Leica Customer Care department can retrofit many Leica M
lenses with 6-bit coding. (Address, see p. 108).
• When using the Leica Tri-Elmar-M 1:4/16-18-21mm ASPH., the
set focal length is not transferred to the camera and thus is not
included in the EXIF data for pictures.
• By contrast, the Leica Tri-Elmar-M 1:4/28-35-50mm ASPH
features mechanical transfer of the set focal length to the cam-
era, necessary to display the appropriate bright line frame in the
viewfinder, which is scanned by the camera's electronics and
used for focal-length-specific compensation. This applies to all
three versions of the lens (item nos. 11 625, 11 890 and 11
894).
