[Leica] 6 bit permanent flange adapters: has anyone tried one?

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

You need the correct mount with the right tab to identify the lens data 
also.  I know, I bought a new 21 Elmarit Asph M back in '08 and it was 6 bit 
coded at the factory, it would not register the lens data when mounted on my 
M8, it did not bring up the correct set of frame lines (yes I know the M8 
does not have frame lines for the 21, but it does have to bring up the 28/90 
lines for the data to be recorded, manually selecting them with the frame 
lever made the data show up).  At Photokina, I had the Leica tech guys 
looked at it, and it had the wrong mount, but the correct code.  Evidently 
it had the old 21 Elmarit Asph mount. The older mount does not have the 
correct cam on the mount, evidently they changed it when the 6-bit coding 
was applied, and my copy did not get the changed mount cam when coded at the 
factory.  Had it fixed under warranty and now works just fine.  So a 
universal mount with depressions cut into them will not work unless the cams 
on the mount are correct for the lens to be coded.

Cheers,
Gene

I ran them for a while before getting genuine 6-bit adaptors at Solms. I 
guess it depends on the lens, more likely to work on a slow wide than a 75mm 
Summilux as the quality control may not be there. It is a reversible process 
if you do not like what has changed and on some lenses only five screws will 
go back in as one is under the 6-bit code.

Just saw these on eBay. You actually remove the rear plate from your lens 
and replace it with one of these. Then you look up the lens code and fill in 
the counter sunk depressions with (I guess) black enamel or magic marker. 
The idea is that by having actual depressions to fill in, they won't wear 
off like other diy solutions.
