Jiukuic5609 Posted November 20, 2009 Share #1 Posted November 20, 2009 Advertisement (gone after registration) I just bought a Summicron 50mm Type III Rigid from someone on RFF. I received the lens in the mail today and he had mentioned there are some cleaning marks on the front, but after closer inspection it seems like it is a fungus, and not cleaning marks. I snapped a few pics in my apartment tonight and I can't see it in the pics... what should I do. I got a good price on it, should I send to DAG to get CLA'd or is it a lost cause... I've included a pic of the front element. Other than the spots the lens is in very good condition... 1) Are these spots fungus? 2) Can this be cleaned in a CLA by DAG or another Leica dealer? 3) Is it worth going through the hassle or should I try to get my money back?

lct Posted November 20, 2009 Share #2 Posted November 20, 2009 ...1) Are these spots fungus? 2) Can this be cleaned in a CLA by DAG or another Leica dealer? 3) Is it worth going through the hassle or should I try to get my money back?... 1. Lens fungus looks like small spiderwebs in my experience so i would say no at first glance but there are many sorts of fungus (fungi?) i've been told so i'm not sure of that. 2. DAG or Sherry Krauter in the US. Fungus needs dismantling and cleaning the lens to avoid a relapse generally. 3. Depends on the price of the lens. Given that it was built in 1970, i doubt your seller has to refund you but i would ask him if i were you. Better buy a clean lens anyway. Link to post Share on other sites More sharing options...
sfokevin Posted November 20, 2009 Share #3 Posted November 20, 2009 If it is fungus it looks like it is just on the outer lens and not inside between the elements so any repair should be of minor cost... Since at this stage the fungus does not effect image quality you can just live with it - If you take this course you need to stop the fungus from growing/spreading... Store it with a bright light shining into the lens or if you have a flash gun shoot it into the lens... you want to kill the spores. As for the seller it sounds like they may not have know what it was - And they did disclose there was a flaw - IMO they acted in good faith...

Jiukuic5609 Posted November 20, 2009 Author Share #4 Posted November 20, 2009 Here is a closer-up picture. It doesn't really look like spiderwebs and it is on the outside of the front element... Link to post Share on other sites More sharing options...
Jiukuic5609 Posted November 20, 2009 Author Share #5 Posted November 20, 2009 I have no problem with the seller and he offered it at a good price. My concern is if it is a fungus, I want to either fix it or kill it as I don't want it affecting my other m lenses or m8... Link to post Share on other sites More sharing options...
Guest mc_k Posted November 20, 2009 Share #6 Posted November 20, 2009 To anyone: have you ever had a mold problem using the leather Leica cases for lens storage? Link to post Share on other sites More sharing options...
andybarton Posted November 20, 2009 Share #7 Posted November 20, 2009 Advertisement (gone after registration) Unless you live in the tropics, you are better off storing your lenses on a shelf, where the air can flow around them easily. I would never store mine in the leather cases - who knows what sort of tanning chemicals might be slowly leaching out of them. Link to post Share on other sites More sharing options...
