As I posted previously [1, 2], Leica have a coding scheme for their lenses so that the new digital M8 body can automatically identify the mounted lens. It turns out that you can use a marker to code the lenses rather than paying Leica US $120 per lens for six dots of paint. You can use the same method to trick the body into thinking you have a different lens mounted than you actually do.
Check out this how-to by Mike Prevette on the Leica user forums for details.
