colorflow Posted November 20, 2009 Share #1 Posted November 20, 2009 Advertisement (gone after registration) This is interesting. I just bought a 90mm fat tele-elmarit which is of course uncoded. But my M8.2 knows it is a 90mm lens and the exif even knows it is the "tele-elmarit type II". The code for that lens is 000100 which is just one black mark with the rest all white. Looks like there is a screw head about where the black bit is supposed to be. I guess it is being read as a black bit and the chrome being read as white.

luigi bertolotti Posted November 20, 2009 Share #2 Posted November 20, 2009 That's curios... seems to me my fat Tele Elmarit doesn't do like this... but can be I never set lens rec. on with it... tonight I'll try... Link to post Share on other sites More sharing options...
stunsworth Posted November 20, 2009 Share #3 Posted November 20, 2009 This has been reported before. I've had something similar with a Voigtlander 90mm lens. I was using it with an adaptor that had a cut out near the code sensor. A few shots were recorded as a 24mm Elmarit. Link to post Share on other sites More sharing options...

Perhaps the screw head needs to be a little dirty too?? Link to post Share on other sites More sharing options...

epand56 Posted November 20, 2009 Share #6 Posted November 20, 2009 They say it is due to one of the screws in the mount on the right place... Link to post Share on other sites More sharing options...
nhabedi Posted November 20, 2009 Share #7 Posted November 20, 2009 Advertisement (gone after registration) Yep, I have the same with my pre-ASPH 35mm Summicron. It just happens to have the screw in the right place. Unfortunately, this isn't the case with my even older 50mm Summicron... Link to post Share on other sites More sharing options...
adan Posted November 21, 2009 Share #8 Posted November 21, 2009 I might point out that the "fat" Tele-Elmarit was the FIRST version - the "Tele-Elmarit type II" is the thin version, so your M8 is recognizing the "wrong" lens.... not that it matters - the corrections needed (probably zero) would be about the same regardless. And, yes, it is a screw head that acts as a "black pit" to simulate the coding. My M8s were promiscuous - they'd recognize anything with a 28/90 mount as a Tele-Elmarit 90 type II, including my v. 4 28mm and my 90 Summicron, thanks to the screw head (and in the absence of real coding).

colorflow Posted November 21, 2009 Author Share #9 Posted November 21, 2009 You are right Andy corrections for 90's are minor. This coincidence is useful for me since I can distinguish pictures taken with this lens from those taken with my Cron AA. Link to post Share on other sites More sharing options...
luigi bertolotti Posted November 21, 2009 Share #10 Posted November 21, 2009 Just tested my Tele Elmarit 90 ("nano" - chrome 2.070.786 - 6 screws into the mount) : it is NOT recognized by my M8 - no data about lens. Can be it depends on the position of the screws' cut... they look someway "random" in my item... but all very "clean" Link to post Share on other sites More sharing options...
colorflow Posted November 21, 2009 Author Share #11 Posted November 21, 2009 Luigi: Mine is 2489663. If you place the mounting slot at 12 o'clock, there is a screw between the 4 and 5 o'clock position (closer to 4 than 5). That must be the screw my M8.2 is reading. It is not dirty, but seems not to reflect as much light. Link to post Share on other sites More sharing options...
luigi bertolotti Posted November 22, 2009 Share #12 Posted November 22, 2009 I always like to have the opportunity to use my DR Summicron... This is the back of my lens, the evidenced screw is the one you spoke of, that is inside the bit-reading stripe... my guess is that, being the screw's head cut almost "horizontal", the "black area" is too small to trigger the bit sensor.

colorflow Posted November 22, 2009 Author Share #13 Posted November 22, 2009 You can try to paint the screw head black. But that would, of course, only be useful for the Tele-Elmarit. Link to post Share on other sites More sharing options...
luigi bertolotti Posted November 22, 2009 Share #14 Posted November 22, 2009 This thread made me think to do, indeed... but I just bought a like-new Elmarit-M 90... my beloved "nano" is going to reirement (btw... ALSO the new 90 is uncoded..., and not recognized ) Link to post Share on other sites More sharing options...
