Subject: [Leica] Uncoded lenses on the M8

Some screw mount lenses can be misread by the sensor if they have a cut out
in the adaptor near the sensor. I have a Voigtlander 90mm lens that has once
or twice been seen as a 21mm lens by the camera, with resulting colour
shifts towards the edges of the frame.

Also a screw in the right place can fool the M8 into thinking a certain lens
is mounted.

So it's to do with lens detection and incorrect processing rather than with
breaking the camera.
