jaapv Posted December 4, 2015 Share #21 Posted December 4, 2015 Advertisement (gone after registration) I have no idea what's wrong, but I'm curious about it being irreparable. Can't the affected elements be replaced or are replacements not available? I had a similar question about some older lenses, which it seems were made with notoriously soft glass at the front element, and are commonly scratched from cleaning. Maybe it's not economically worthwhile to make replacement elements/groups for lenses? Leica probably does not stock the glass any more. But you can always ask.

pgk Posted December 4, 2015 Share #22 Posted December 4, 2015 Leica probably does not stock the glass any more. But you can always ask. According to the forum's wiki the lens was last produced in 2007 - only 8 years ago - I'd be surprised if spares (even cemented elements) are already unavailable. Well worth asking I'd say.

jdlaing Posted December 4, 2015 Share #24 Posted December 4, 2015 If it was a car from that period, would you drive it? Depends on how many megapixels it has. Link to post Share on other sites More sharing options...
wattsy Posted December 5, 2015 Share #25 Posted December 5, 2015 Leica probably does not stock the glass any more. But you can always ask. I'd be amazed (and disappointed) if Leica didn't stock spares (including lens elements) for a flagship lens that was still being sold new in 2010.

jaapv Posted December 5, 2015 Share #26 Posted December 5, 2015 Sorry - I thought he meant a far older example . It is weird that a lens of this age should show this. Link to post Share on other sites More sharing options...

AAK Posted December 7, 2015 Share #28 Posted December 7, 2015 Leica probably does not stock the glass any more. But you can always ask. I wasn't clear. I was wondering if it would be economically feasible to re-manufacture replacement elements for old lenses. Link to post Share on other sites More sharing options...
pgk Posted December 7, 2015 Share #29 Posted December 7, 2015 I wasn't clear. I was wondering if it would be economically feasible to re-manufacture replacement elements for old lenses. According to the Wiki here on the forum, there were less than 20,000 of these lenses made. Leica probably have or had a stock of spares based on their previous experience of stock requirements for such a production figure and I would assume that if this spares stock was used up, the very low numbers of lenses requiring out of stock parts would make the re-manufacture completely uneconomic. Other (older) lenses have no spare element availability despite greater production figures and more being (by now) in need of replacement elements, so I'd say that its extremely unlikely that re-manufacture would take place.

Peter Branch Posted December 7, 2015 Share #30 Posted December 7, 2015 I had a similar experience with a 90mm f/2 Summicron-R about 20 years ago which Leica told me was separation of the cemented elements caused by heat. Apparently they could be fairly certain that that was the cause because the separation was symmetrical. It had probably happened when my camera bag spent a day on the roof of a vehicle in Morocco. The lens was ~25 years old at the time but Leica, bless them, had a replacement cemented group available. It was their last one. If they had not had it then it would not have been possible to repair the lens. The cost of repair at the time was about £300 GBP which was covered by my insurance.
