Advertisement Posted October 10, 2022 Posted October 10, 2022 Hi Film Hunter, Take a look here Strange Leitz Elmar 5cm 3.5 from a Leica ii converted to iiia. I'm sure you'll find what you were looking for!
romanus53 Posted October 10, 2022 Share #2 Posted October 10, 2022 As it has an IR-Index it might be converted or remounted after appr. 1935. The number is hard to decipher but both are close to 1933 and should match the body. I wouldn't invest in fixing the glas as you have already enough 😉. Shure it is separation in the cemented cell in the back? looks like some other "defect" on front, is it coated? 1 Link to post Share on other sites More sharing options...

Film Hunter Posted October 10, 2022 Author Share #4 Posted October 10, 2022 The body is made around 1932 serial number 77xxx Link to post Share on other sites More sharing options...
willeica Posted October 10, 2022 Share #5 Posted October 10, 2022 This could be 160000 or 163000. I'll mention 2 50mm/5cm Elmar batches from 1933 that could be relevant 156501 -160000 163001 - 165000 163000 is supposed to be for a Mountain Elmar, but sometimes you will find items at the edge of batches which are from different model ranges. There are many variations of the 50mm/5cm Elmar, at least 25 and probably more. It is hard to find people who will work on lenses. Leica Classics in Wetzlar will probably quote you a price, but you would probably be able to buy another one for that price or even for less.

frame-it Posted October 10, 2022 Share #6 Posted October 10, 2022 it could be 163000 or 168000, but after adjusting the pic it looks like 138000?? Welcome, dear visitor!

And the glass defect does not look like separation to me (Elmar 5 cm lenses are not known for that problem anyway). Link to post Share on other sites More sharing options...
jerzy Posted October 10, 2022 Share #9 Posted October 10, 2022 separation in Elmar 5cm happens rare but is possible as well. This is how the rear group in my Elmar was. Warming up the rear group to 90C and pressing both lenses together helped to distribute canada balsam between the lenses. But you need to disassembly the lens and it does not always work. Alternative is to remove cemented group from the mount, separate completly, clean and re- cement. Pretty complex task. Welcome, dear visitor!

I have seen separation in lenses several times, and it never looked like this, not even close. This looks like some sort of fungus to me. Of course, if you heat up the lens group and then press the lens elements together, you will re-shift the still existing Canada balsam, which has softened due to the elevated temperature, into those regions were fungus has 'eaten' the balsam. But that does not mean those structures have been caused by normal lens separation. Lens separation is a mechanical process, and it will in my view not be able to form such organic looking structures. vor 1 Stunde schrieb nitroplait: Very organic looking - quite fascinating. I understand why some may mistake it for fungus. As explained above, I would be very, very surprised if it were not fungus. 1 Link to post Share on other sites More sharing options...

I do not know what was a reason, but I believe that canada balsam dried out on some spots therefore such unusual pattern. Here is another example of separation, this time Summar - notice round spots, again, canada balsam dried. On the right photo lens group is separated Welcome, dear visitor!

I have never seen fungus develop between the elements of a cemented pair. Particularly since the pattern is in the center and does not start along an edge of the interface. But I have been surprised before, especially how fungus can get to the most difficult to reach surfaces and leave other surfaces clean. Link to post Share on other sites More sharing options...

Well, Canada balsam is an organic substance to start with. Perhaps a tiny amount of fungus spore was part of the substance when it was processed at the time, and just needed the right environmental conditions to grow.
