crlong Posted May 9, 2018 Share #1 Posted May 9, 2018 (edited) Advertisement (gone after registration) I purchased this circa-80s 1.0 noctilux online from a dealer. I am within the return window. I wanted to ask about this residue on the aperture blades. Its hard to get in focus, but there are a couple of spots that appear to be white with a little bit of slightly darker bleed around them. They are definitely on the blades because they move with the blades. I don't see anything in the glass itself when I look through it. Should I be worried about this down the road if I hold on to it?

Advertisement Posted May 9, 2018 Posted May 9, 2018 Hi crlong, Take a look here Noctilux - is this fungus?. I'm sure you'll find what you were looking for!
Peter Kilmister Posted May 9, 2018 Share #2 Posted May 9, 2018 Unfortunately it is not a very clear picture. However, it does look like a fungus spore. I would return the lens as you have the option. Don't wait! Send it back ASAP. That way it is someone else's problem. Quote Link to post Share on other sites More sharing options...
LeicaR10 Posted May 9, 2018 Share #3 Posted May 9, 2018 Crlong, I totally agree with Peter in Post 2 and based on my experience with fungus on M lenses while stationed in Panama years ago. Send it back ASAP. r/ Mark Quote Link to post Share on other sites More sharing options...
Steve McGarrett Posted May 10, 2018 Share #4 Posted May 10, 2018 Impossible to see anything in that picture However, if it's ON the iris blades, it's not a glass fungus, it's gotta be some dirt or grease stuck in the blades... 2 Quote Link to post Share on other sites More sharing options...
jaapv Posted May 10, 2018 Share #5 Posted May 10, 2018 Agree with Steve. Gunk on the iris blades is not destructive glass fungus. A simple CLA will take care of it. Contact the dealer before returning. In my experience a good dealer will take the lens in and return it serviced without extra charge. 2 Quote Link to post Share on other sites More sharing options...
crlong Posted May 10, 2018 Author Share #6 Posted May 10, 2018 Ok thank you for the input. I tried my best on the picture. It is very hard to photograph even with a macro lens. I contacted the seller and expressed my concerns. Quote Link to post Share on other sites More sharing options...
Donzo98 Posted May 10, 2018 Share #7 Posted May 10, 2018 Advertisement (gone after registration) If it’s on the blades only,,, not fungus. If they get you a CLA... keep it Quote Link to post Share on other sites More sharing options...
jaapv Posted May 10, 2018 Share #8 Posted May 10, 2018 As far as I can make out from the image, the lens is filthy inside. They shouldn't have sold it without CLA in the first place. Quote Link to post Share on other sites More sharing options...
crlong Posted May 10, 2018 Author Share #9 Posted May 10, 2018 Here are better photos. Also see the marked spot which looks like there is some internal paint loss. Is this normal considering the age?

pgk Posted May 10, 2018 Share #10 Posted May 10, 2018 Looks like it could just be Schneideritis - google it to find out more. The alternative is separation but I doubt that you'd get separation of two different cemented lenses in the same place without an impact mark to indicate why.

pico Posted May 10, 2018 Share #11 Posted May 10, 2018 Fungus in a Noctilux is a yet-to-be appreciated 'secret sauce' to fantastic, always unique bokeh. 1 Quote Link to post Share on other sites More sharing options...
Herr Barnack Posted May 10, 2018 Share #12 Posted May 10, 2018 I would return it and ask that the dealer have it CLAed at their expense. Don't let your warranty time frame expire before doing so! Quote Link to post Share on other sites More sharing options...
