[Leica] Lenses without 6 bit code in M8

[hoppyman at bigpond.net.au (G Hopkinson)]

Claudio, the latest position from Leica is that:
Almost all lenses will apparently still work well without it, which is what 
Eric is saying, I think.
If you have the code it will record the focal length in the EXIF data.
Some flash functions are improved
Dependant on which firmware version installed, the camera will apply 
additional vignetting correction and correction of cyan in the
corners of the frame (when using the recommended IR filters).

At least in the recent LFI magazines Leica is suggesting that the 6 bit 
coding should be used with lenses of 35mm or wider for the
corrections listed above.

This is only theory from studying available references. M8 owners will be 
able to tell you what they consider the practical
importance of the coding to be.

Cheers
Hoppy
