Leica M lens codes

I've just got my Leica Summicron 1:2/50mm lens updated to work with 6bit coding on M8.2

It's simple to do, just have a look at the following links which show required coding and how to make lens 6 bit coding for Leica M8 and Leica M8.2

Basically draw lines using black dry safe permanent pen, like you use to write on CDs DVDs. Just make sure it's dried (I applied a piece of paper to soak up any excess ink).

Now my lens automatically adds info to the EXIF. Sweet!
