While checking through the box my lenses came back from coding in, SWMBO discovered a pink envelope containing a leaflet in 6 languages which confirms the name of the Leica digital M as "Leica M8".

"Notes on using Leica M lenses with 6-bit code on analog and digital Leica M cameras

Type Marking

This Leica M lens is equipped with a 6-bit barcode marking on its bayonet flange for use on the digital LEICA M8. This marking enables digital M models to detect the type of lens attached by using the sensors in the camera's bayonet flange.

The LEICA M8 writes the lens information it has read to the EXIF file and uses this for processor-aided optimization of image quality. This code also allows the focal length of the lens to be displayed in the camera monitor.

This Leica M lens can also be used on Leica M models up to the LEICA M7.

Supplement to the tips on lens care for type-marked Leica M lenses

Ensure that you do not apply too much grease to the bayonet flange and especially that you leave the lens code area ungreased, otherwise residues of grease might become lodged in the recess, allowing more dirt to accumulate. This could ultimately impair the legibility of the code and consequently the camera functions of the LEICA M8."
