pajamies Posted March 29, 2014 Author Share #901 Posted March 29, 2014 Advertisement (gone after registration) I finally made it to the manor again, so here is a pair of photos with the Summicron 50/2 AA at f16, the second one overexposed, as requested by lct. Both were taken at ISO 200, the first was exposed 1/90 sec and the latter photo 1/45. The sun was not shining into the optics, but the inside of the built in shade was illuminated by the sun. No shade was used, hand, or otherwise. I cannot detect any central fogging or veiling in either one, suggesting again that Solms has been able to correct the lens.

Advertisement Posted March 29, 2014 Posted March 29, 2014 Hi pajamies, Take a look here APO Summicron 50/2 ASPH: Central veiling flare / fogging. I'm sure you'll find what you were looking for!
algrove Posted March 29, 2014 Share #902 Posted March 29, 2014 pajamies I think for your test to be conclusive we should see every lens you have with the same shot from correct exposure low f-stop to the f16/f22 over exposure range. I am still not sure this lens has potential in my bag. You know better yet you should print these out A3 and send them to each of us. Link to post Share on other sites More sharing options...

It is not really my purpose to convince anyone, I'm just reporting what I see in my amateur amateur capacity. Rigorous testing is beyond me. I am happy to see that the flaring behavior of he lens that I saw last summer was essentially diminished after reparation in Solms I happened to photograph the same scene with my Noctilux at f16 on my Leica M today, see below.

algrove Posted March 29, 2014 Share #905 Posted March 29, 2014 That Noctilux shot looks great. Thanks for all your work. Do you ever print your keepers? Not a suggestion, but just a casual question. Link to post Share on other sites More sharing options...
pajamies Posted March 29, 2014 Author Share #906 Posted March 29, 2014 Thanks for your compliment, Algrove ! As to printing, I have made a few attempts at it, but the results have shown that I need more training, plus perhaps a calibrated Eizo display etc Link to post Share on other sites More sharing options...
algrove Posted March 30, 2014 Share #907 Posted March 30, 2014 Advertisement (gone after registration) Thanks for your compliment, Algrove !As to printing, I have made a few attempts at it, but the results have shown that I need more training, plus perhaps a calibrated Eizo display etc I only started printing 2 years ago and that is now my most satisfying result from all the hard work. For me it completes the circle. I seldom post because I feel it is not a finished product on a screen. PM me if you want/need any suggestions on how/what got me going with printing. BTW, I do not own an Eizo. Link to post Share on other sites More sharing options...

I seldom post because I feel it is not a finished product on a screen.. But printing your work need not preclude posting and visa versa! I have a background of working in photographic printing and so print all my images that pass muster, though unfortunately not larger than A3+ as I only have an Epson R3000. I agree with your remark about the finished product, however there is a place for both prints and for images posted online, just as there is for film and digital. Why restrict yourself?

CheshireCat Posted July 25, 2014 Share #912 Posted July 25, 2014 Brand new is fine. Sorry for not going through all 912 posts. Can someone please summarize what do we know about this issue at the moment, such as: 1) What was the cause ? 2) What was the fix ? 3) Are fixed lenses ok ? 4) What should I check (e.g. serial number) if I need to rent or buy the lens second hand. Thanks in advance. Link to post Share on other sites More sharing options...
jbl Posted July 25, 2014 Share #913 Posted July 25, 2014 I think the short answer is roughy this. Some number of the early models (420xxxx serial number range I think) exhibited this issue. Mine is in that range and never did. The fix is to send it to Leica and they'll fix it. I've read some people say the lens didn't come back quite the same, but I don't know the details on that. As for what to check, take a shot with the sun low in the sky coming in at an angle (think a backlit portrait). It'll flare obscenely if you have the problem. I would have expected this sort of a shot to reveal it, but I've never seen it in my early copy. Welcome, dear visitor!
