Giuliobigazzi Posted October 19, 2023 Share #1  Posted October 19, 2023 Advertisement (gone after registration) Hello, I have this late fat Elmar serial 135984 that for some reason has an extra ring under the second (aluminium) knurled ring. It goes without saying that this lens does not reach infinity. What may have the purpose for such a strange hack have been? Welcome, dear visitor!

Pyrogallol Posted October 20, 2023 Share #2 Â Posted October 20, 2023 If you unscrew the lenshead can you remove that ring? Link to post Share on other sites More sharing options...
Giuliobigazzi Posted October 20, 2023 Author Share #3  Posted October 20, 2023 That ring feels like it’s welded or glued on the aluminium ring that would have the thread on. The brass part below that spins freely so not sure what happened to this poor lens Link to post Share on other sites More sharing options...
pgk Posted October 20, 2023 Share #4 Â Posted October 20, 2023 Does it work as it should (focus correctly)? Link to post Share on other sites More sharing options...
Giuliobigazzi Posted October 20, 2023 Author Share #5 Â Posted October 20, 2023 Seems to focus correctly but maximum distance is about 10m. Rangefinder patch is also short so something must have been changed internally. maybe modded to achieve closer focus? Link to post Share on other sites More sharing options...
pgk Posted October 20, 2023 Share #6 Â Posted October 20, 2023 Sounds like it may need attention internally - cross threaded and jammed perhaps? Do you have a good repairer locally? Link to post Share on other sites More sharing options...
spydrxx Posted October 20, 2023 Share #7 Â Posted October 20, 2023 Advertisement (gone after registration) It does look like a large shim type mod to achieve close focus. Have you tried removing it and using the lens for infinity focus? Link to post Share on other sites More sharing options...

I wonder if it could have been done for some repro usage without RF coupling... as a do it yourself modification, before that Leitz listed the several devices and kits for this purpose 1 Link to post Share on other sites More sharing options...

The brass part below that spins freely so not sure what happened to this poor lens I don’t think any part of the original lens was aluminium, only brass. My one looks like this, the widest knurled ring is flush with the top of the focussing mount. Welcome, dear visitor!

Pyrogallol Posted October 20, 2023 Share #10  Posted October 20, 2023 (edited) Now that I have removed the lenshead from the focussing mount the lenshead base does look more like aluminium than brass?
