alechino Posted March 22, 2007 Share #1 Posted March 22, 2007 Advertisement (gone after registration) I have bought a Summaron 35 mm (payed 30 euro), with an internal glass element broken near borders The lens however works well full wide too, at f4 is impossible to see the broken glass Do you think it is possible repair the lens changing the element? Is it convenient sending it at Wetzlar ? Many thanks! Mauro Italy Rome Link to post Share on other sites More sharing options...
Advertisement Posted March 22, 2007 Posted March 22, 2007 Hi alechino, Take a look here A curious lens problem - Summaron 35 f2,8 - impossible to repair?. I'm sure you'll find what you were looking for!
wizard Posted March 23, 2007 Share #2 Posted March 23, 2007 Are you sure a lens element is actually broken? Very often, beginning lens group separation (which starts at the borders of the elements) looks like there is a crack in an element. If it is separation, a good lens repairman can recement the elements. Malcolm Taylor in the UK is one address for this kind of job I'd think. If in fact an element is broken, I doubt that Leica will have replacement elements available. On the other hand, they still might, as this version of the Summaron was produced for a long time. Just ask them. However, to the best of my knowledge, they do not repair lenses below serial no. 2 000 000 anymore. In any case, repair will not come cheap.

jc_braconi Posted March 23, 2007 Share #3 Posted March 23, 2007 Hello, I have 2 Elmar 2.8/50 Screw mount s/n 13xxxxx, 16xxxxx in Solms for front element changing, the cost of the glass only is 1/4 of the total price. If you cannot see any problem let it as it is except if the cosmetic hurt you ( I can understand the feeling ) Regards JC Link to post Share on other sites More sharing options...

earleygallery Posted March 23, 2007 Share #5 Posted March 23, 2007 Well it does look like a crack. I would also leave it alone and just enjoy using it, if it produces good results. My father had (I still have) a Retina lllc also with a crack in the lens that never caused any problems. For 30 euros its a bargain. You'd probably be better off just buying a perfect example if that's what you're after, rather than paying for yours to be repaired. Link to post Share on other sites More sharing options...

lars_bergquist Posted March 27, 2007 Share #7 Posted March 27, 2007 Advertisement (gone after registration) The Summaron is still a very competent 35 mm lens. At apertures wider than 5.6 it is actually far better than the legendary first Summicron, and it was a better buy for most people. So most people did buy it, and it is quite common. So, if you actually like to use the lens – and it is well worth using, especially on a nice old M2 of course! – you may well want to get a specimen with perfect glass. Try http://www.leicashop.com for instance, they have always given me good stuff and prompt service. The old man from the Age of Anastigmats Link to post Share on other sites More sharing options...
wizard Posted March 28, 2007 Share #8 Posted March 28, 2007 At apertures wider than 5.6 it is actually far better than the legendary first Summicron, ... Lars, you must have had a very bad copy of the first Summicron 35. Even Leitz at the time said that the Summicron is their best 35mm lens, reaching its optimum at f4. Having used both lenses, my own experience is different from yours: The Summaron is good, but the Summicron is better (sharper, more contrast, more vivid colours).

Now I have found a new summaron f2,8 for m3, but without googles , perfect lens Do you think I can change mount mechanical section from one lens to other?

wizard Posted April 2, 2007 Share #10 Posted April 2, 2007 Now I have found a new summaron f2,8 for m3, but without googles , perfect lens Do you think I can change mount mechanical section from one lens to other? Mauro, I noted that your first Summaron (the one with the crack) was also without goggles. If the second one is also an original non-goggled lens, then yes, parts should be interchangeable. Parts are, however, NOT interchangeable between goggled and non-goggled lenses (even if the goggles have been removed, as your comment seems to indicate). The focussing helicoils of goggled and non-goggled lenses are different (to be noted also by the minimum focussing distance, which is 0.65m with the goggled lens and 0.7m with the non-goggled lens). Also, the goggled lens will bring up the 50mm brightline frame, whereas the non-goggled lens will bring up the 35mm brightline frame. Either lens can be used on all Leica M cameras, however (if a non-goggled lens is used on an M3, a separate 35mm finder will be necessary).

alechino Posted April 3, 2007 Author Share #11 Posted April 3, 2007 Thx Andy The problem is I have broken googles of the summaron with googles: now is not possible using that with any leica m, having the right focusing view? Thx again Mauro Link to post Share on other sites More sharing options...
wizard Posted April 4, 2007 Share #12 Posted April 4, 2007 The problem is I have broken googles of the summaron with googles: now is not possible using that with any leica m, having the right focusing view? Correct, in order to fully use a goggled lens on any M Leica, the goggles have to be present. Of course, you can use the goggled lens without goggles when the lens is set to infinity (for example when doing landscape photography) and use any suitable 35mm finder, either external or internal.
