rirakuma Posted January 5, 2013 Share #1 Posted January 5, 2013 Advertisement (gone after registration) Hi guys, sorry I'm new to this forum but I'm looking for some advice on a lens I've purchased. I'm planning to change to a Leica system but at the moment I'm using a Nikon system and I've purchased a 35mm Summilux in anticipation of the M to come. I bought the lens secondhand on ebay just before Christmas and I didn't check it thoroughly enough but it seems like theres oil on the aperture blades. I looked back at the pictures from the listing and it seems to show it there as well but its not very clear so I did not recognise it out when I was viewing them. Is this anything I should worry about? The seller had listed it to be in perfect condition as shown here: eBay Australia: Buy new & used fashion, electronics & home d�r' If you look closely at the second last picture you can see the marks consistent with the picture I took: http://img152.imageshack.us/img152/7306/dsc7254.jpg I have not used this lens at all and it has been stored in the leather pouch ever since the purchase. Any help would be greatly appreciated. Thank you! -Rocky Quote Link to post Share on other sites More sharing options...

dpitt Posted January 5, 2013 Share #2 Posted January 5, 2013 Hi Rocky, I understand your concern. This is not a cheap lens! Although I bought several lenses second hand, I would also not have noticed it on the ebay photos. The problem can be easily fixed by a CLA as far as I can see, so you do not need to worry to much. I do not know if the lens will be safe to use without CLA and if the problem will affect IQ. Main issue will be that you will need to send the lens in with Leica or a Leica technician and miss it for a few weeks during the CLA. It is up to you if that is enough to claim compensation from the ebay seller or even return the lens. Have a look here for info about CLA: http://www.l-camera-forum.com/leica-forum/customer-forum/176369-repair-specialists.html I do have good experiences with Will van Manen of Kamera service in Zoetermeer.

TomB_tx Posted January 5, 2013 Share #3 Posted January 5, 2013 I don't see anything that would be a concern to me. It looks quite different from the "wet" look of oil that I've seen, which can migrate to lens surfaces. It may well be just a smear of the anti-friction coating on the blades. Remember - oil on the blades is primarily a problem with SLR lenses as it can slow down the "snap-close" of an automatic diaphragm - which isn't the way a rangefinder lens functions. Oil on very old Leica lenses can stick the blades in place as it oxidizes and dries out. Even that wouldn't be an issue with this lens for another 60 years. I'd just use the lens and enjoy it.

earleygallery Posted January 5, 2013 Share #4 Posted January 5, 2013 I wouldn't worry about that. Try leaving the lens wide open for a while (just leave it in the case at f1.4 whist you're not using it) and this might clear the oil (it worked on my Summicron)!

rirakuma Posted January 6, 2013 Author Share #5 Posted January 6, 2013 Thanks for the replies ! I'm going to keep the lens and leave it wide open while I wait for the body to arrive. Can't wait to make the switch and start contributing on this forum. Quote Link to post Share on other sites More sharing options...
