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?
