pyang921 Posted January 11, 2014 Share #1 Â Posted January 11, 2014 Advertisement (gone after registration) Hello there! I just got my new Noctilux 0.95 from Amazon and immediately I found that the aperture ring on the lens is inverted, i.e. the numbers are facing the bottom of the lens and the aperture white dot is facing down as well. The lens itself is functional and not defective but this makes the adjustment of the aperture really inconvenient. Any way to fix this? Thanks!

wlaidlaw Posted January 11, 2014 Share #3  Posted January 11, 2014 Hello there!

The lens itself is functional and not defective but this makes the adjustment of the aperture really inconvenient. Any way to fix this? Thanks!  Just for reference I post below an image of what the aperture ring should look like. As yours is inverted, I assume the aperture works the wrong way round as well i.e at 0.95, the diaphragm is fully shut.  As a fellow sufferer of a faulty brand new Noctilux, you have my every sympathy. Mine is back at Solms at the moment for investigation. Once that is done, I will have to discuss with them whether to correct my current lens or replace with another new one.  Wilson Welcome, dear visitor!

Bill W Posted January 12, 2014 Share #4 Â Posted January 12, 2014 Not sure how it could have been installed if it was inverted. Link to post Share on other sites More sharing options...
Tonki-M Posted January 12, 2014 Share #5 Â Posted January 12, 2014 not sure if QC is asleep or didnt even bother to check it at all. So much for meticulously process everything at all stages of the product. German engineering...great indeed. QC...not so much. Link to post Share on other sites More sharing options...
pop Posted January 12, 2014 Share #6  Posted January 12, 2014 TO says that the numbers face from the user away; hence, the ring was turned 90° around the optical axis of the lens, not back to front,I believe. Link to post Share on other sites More sharing options...
jaapv Posted January 12, 2014 Share #7 Â Posted January 12, 2014 Advertisement (gone after registration) It seems more logical to presume a batch of rings was engraved upside down. Link to post Share on other sites More sharing options...
wattsy Posted January 12, 2014 Share #8  Posted January 12, 2014 Leica have a bit more history than you'd think they would like with putting the aperture ring on incorrectly.  http://www.l-camera-forum.com/leica-forum/leica-m8-forum/84376-another-leica-qc-problem.html  http://www.l-camera-forum.com/leica-forum/customer-forum/89722-my-new-apo-summicron-75-asph.html Link to post Share on other sites More sharing options...

250swb Posted January 12, 2014 Share #10 Â Posted January 12, 2014 I can perhaps see how the aperture ring can be inverted, but the white dot on the wrong side as well???? That is another part entirely and I can't really see how it could all fit together and work. Â Steve Link to post Share on other sites More sharing options...
wlaidlaw Posted January 12, 2014 Share #11 Â Posted January 12, 2014 Unless the whole aperture diaphragm sub-assembly is fitted upside down, fitting the ring upside down must mean that at 0.95 the diaphragm is shut and at f16 wide open. If the OP is correct and the white dot is at the wrong side it must be the whole ring that is upside down not just wrongly engraved because the white dot is on the smooth section and the aperture on a smooth arc between knurled sections. I would like to see a photo from the OP unless the whole thing is a wind up. Â Wilson Link to post Share on other sites More sharing options...

Paul J Posted January 12, 2014 Share #13 Â Posted January 12, 2014 I thought my aperture ring was on the wrong way around until I realised I was pointing the camera the wrong way. As it happens, you point the shiny glass bit of the lens at the subject. Link to post Share on other sites More sharing options...
earleygallery Posted January 12, 2014 Share #14  Posted January 12, 2014 Noctilux from Amazon? Seems like a wind up to me - let's see a picture of the lens.  The Noctilux is listed on amazon.com so presumably people buy them that way. I don't see why this should be suspected as a wind-up given similar cases we know about.  But yes, it'd be interesting to see a photo of the lens.

wlaidlaw Posted January 12, 2014 Share #15  Posted January 12, 2014 I post a link to a post by Stefan Daniel responding to the folks whose aperture rings were wrongly positioned (turned 90º and 180º around the lens) http://www.l-camera-forum.com/leica-forum/customer-forum/89722-my-new-apo-summicron-75-asph.html#post940053  Well Herr Daniel, you say you were shocked by this failure of QC but not I think shocked enough, from the litany of really silly errors that have sailed past your QC team over the last few months. When Leica used rather primitive visual checking methods for RF focus, I can understand some lenses going out of the door with a bit of back or front focus but when the same check now takes seconds on a well calibrated M240, there is no excuse whatsoever. As for wrongly positioned Aperture rings, as I posted in another thread, they must employ Mr. Magoo as a checker or they are just not doing it.  Wilson Link to post Share on other sites More sharing options...
LeicaPassion Posted January 12, 2014 Share #16 Â Posted January 12, 2014 20 years ago, I received a brand new, fully inspected 90mm summicron-R lens with a half-inch bubble in the front element. My dealer contacted the head of Leica US about the blunder. A new lens was sent immediately. Link to post Share on other sites More sharing options...

It must be quite impossible to fit it upside down and have a working mechanism. Link to post Share on other sites More sharing options...

It must be quite impossible to fit it upside down and have a working mechanism. Â Jaap, Â I doubt it as well but I cannot otherwise see how the ring can be fitted on reversed. I assume that there is a slot on one edge of the moving ring, which picks up on a tab on the diaphragm mechanism. The OP says it works. The whole story is difficult to comprehend.

agfa100 Posted January 12, 2014 Share #19 Â Posted January 12, 2014 Back in the 1970 I worked in a camera store and we got a new M-4 in that had a bad lens mount you could not mount ANY lens on the camera. They replaced it rear quick, but kept telling us it could not happen and what were we doing wrong but the rep. came in and swapped it out for us. Stuff happens but we all remember when it happens to Leica because of the cost and they keep telling us how great their QC is...... Â wbill Link to post Share on other sites More sharing options...
algrove Posted January 12, 2014 Share #20 Â Posted January 12, 2014 I think a photo of this lens would help us all understand the issue more clearly. How about posting a photo OP? Link to post Share on other sites More sharing options...
