Advertisement Posted October 8, 2013 Posted October 8, 2013 Hi erudolph, Take a look here APO Summicron 50/2 ASPH: Central veiling flare / fogging. I'm sure you'll find what you were looking for!
Ario Arioldi Posted October 8, 2013 Share #442 Posted October 8, 2013 After having eventually discovered that also my APO Summicron suffers under certain circumstances of the infamous flaring issue (as recognized by Leica after examination of my files) I agreed yesterday to send the lens to Solms and I was advised that the turnaround period might be as long as four weeks.

algrove Posted October 8, 2013 Share #443 Posted October 8, 2013 Ario 4 weeks is better than 12 or more that pajamies is experiencing. If his is not back, it only tells me they do not have a fix for it yet. Link to post Share on other sites More sharing options...
k-hawinkler Posted October 9, 2013 Share #444 Posted October 9, 2013 On the M with EVF I wonder whether the new $4k ZEISS 55/1.4 (for Canikon) with adapter isn't a better option? Link to post Share on other sites More sharing options...
lct Posted October 9, 2013 Share #445 Posted October 9, 2013 Much larger and heavier for sure, better i don't know. Link to post Share on other sites More sharing options...
k-hawinkler Posted October 9, 2013 Share #446 Posted October 9, 2013 After heaving followed this thread I might be more interested in using the ZEISS 55/1.4 on my D800E or a FF NEX if the latter materializes. Link to post Share on other sites More sharing options...

The word through the local importer is that the repair in Solms is delayed because of missing part(s) Link to post Share on other sites More sharing options...
platypus Posted October 9, 2013 Share #448 Posted October 9, 2013 After three months or so of casual but frequent use, in differing lighting situations, my APO 50 doesn't seem to have this problem, however, as I follow this thread, I can't stop (paranoidly) imagining that I must be missing something. I wonder how many of these lenses there are out there that do not suffer from the dreaded flare fault. We seem to hear only about those that do.......

Zeiss Otus 55mm f/1.4 APO-Distagon | BH inDepth An interesting read, especially about flare control. Of course, I read this with a pinch of salt. Now the question on my mind is how much variation is there for this lens from copy to copy? I guess, time will tell. The good thing seems to be that in terms of optical excellence Leica might have some competition. Of course, this lens is relatively bulky and is not rangefinder coupled, but with an adapter it could be used on a number of cameras, including an Leica M.

Sam.Yeung Posted October 11, 2013 Share #452 Posted October 11, 2013 APO Summicron 50/2 ASPH: Central veiling flare / fogging My brand new APO Summicron 50/2 ASPH produces flare / fogging under circumstances that should not cause problems, eg overcast sky, without any direct sunlight present. Shading the lens with the hand from above removes the fogging. Diglloyd.com has observed the same phenomenon, and suggests that inadequate blackening of the lens interior may be the culprit. Looking into the lens one can see two silvery rings that could reflect light. Below is a photo of the rings taken with my iPhone.  35 lux fle (11663) also has the same ring!

lct Posted October 11, 2013 Share #454 Posted October 11, 2013 Sean Reid did not report any central veiling flare in his yesterday's review but he did not test the lens at f/11-f/16 so he did not take much risk from this standpoint. Link to post Share on other sites More sharing options...
marknorton Posted October 18, 2013 Share #455 Posted October 18, 2013 My lens is now back in Solms and this is what the work order says: Sent to the Quality Control dept. for further examinations adjust focusing ring optics reflexes adjustment of all parts Not sure what "optics reflexes" means, I expect something is lost in the translation. In any event, I understand that lenses going back are being kept separate from normal service work and (I assume) are going back into the manufacturing QA process. I am not the world's most experienced Leica shooter (nor the most novice) but I was not prepared to trust my judgment that my lens would never flare unexpectedly and I therefore prefer Leica to check it over.

My service order is the same: Sent to Quality Control dept. for further examination optics reflexes adjust focusing ring adjustment of all parts In fact when I was advised that the turnaround might be as long as four weeks, the justification given was that the dept. in charge for this specific issue is the quality control dept.

Albert Andersen Posted October 18, 2013 Share #458 Posted October 18, 2013 My Lux 50 mm asph had the same problem, but after a visit to Solms the lens is now perfect. I do not know what they did, but it works Link to post Share on other sites More sharing options...
marknorton Posted October 18, 2013 Share #459 Posted October 18, 2013 So no flare at f/16 when shooting dark things against the light Mark? I'm sorry, I had not picked this up as a way to reproduce the problem. When I heard Leica were accepting lenses for checking, I decided to let them do the work! I think we can assume "optics reflexes" is more accurately translated as "optical reflections" or similar. Link to post Share on other sites More sharing options...
erudolph Posted October 18, 2013 Share #460 Posted October 18, 2013 Dropped mine off at UPS in San Francisco, September 27, three weeks ago to the day. In today's mail received Repair Estimate from Germany, same as those quoted above, "Anticipated Delivery" November 18. Link to post Share on other sites More sharing options...
