All lenses are 6 screw, just there are two different layouts and one style loses a screw when 6-bitted... john -----Original Message----- Gene.. you order the flanges for the FL of the lens in question.... Remember to count the number of flange screws..... the correct number is either 5 or 6 screws. BTW the screwdriver to use is available through Amazon.com ... order the set of small Phillips head screwdrivers made by WIHA. About $20 for the set... Frank Filippone Red735i at verizon.net 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. john -----Original Message----- From: lug-bounces+john=chiaroscuro.co.nz at leica-users.org [mailto:lug-bounces+john=chiaroscuro.co.nz at leica-users.org] On Behalf Of Lew Schwartz 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. _______________________________________________ Leica Users Group.
