[Leica] DIY 6-bit coding problems

[grduprey at mchsi.com (grduprey at mchsi.com)]

I have 2 lenses that are coded, a 21, and a 28.  Both are coded only because 
i bought them that way, all the rest of my lenses are not coded and the 
images are just great.  The 21 is the only one of yours that really needs 
it, but since it is not a Leica lens you are out of luck, unless you get one 
of the adapters with the recesses built in.  The sharpie and the template 
method is always going to be a problem.

Cheers,
Gene

Maybe this has been queried before, but I'm having trouble coding my  
lenses with a sharpie and this template:  
http://whimster-photography.com/leica_m_lens_codes/template.jpg

My lenses:  CV 21, f/4; CV 35 f/1.2; Canon LTM 35 f/2 with VC M-mount  
adapter, f/2; 35 Asph 'Cron; 50 'Cron IV; 90 thin Tele-Elmar; 90 Leica  
Canada 2.8 (chrome); Leica 135 2.8, goggles.

After coding with a sharpie, the CV 21 is recognized as a 21 when I  
press the Info button on my M8.  The 135 is mis-recognized as a 21.   
The others are not recognized as coded at all.

I'm not sure what I'm doing wrong.  However, when I print off the  
template mentioned above, the diameter seems a bit too wide, so I have  
to kind of guess the correct positioning for the sharpie marks.

Any advice welcomed!
