Hello As this is my first post let me know if this isn't the proper page for this thread. I have been checking my lenses off and on for the past few years for fungus build up. I use a lot of adapted lenses for the M43 and I have some old expensive glass for my 4x5 setup as well. I have noticed dust even in my new lenses which I understand is normal because none of my lenses are sealed. However recently I was checking my Rokkor-x 50mm 1.7 and noticed something that might be a small fungus spot on the edge but I'm not 100% sure. This would be unfortunate because it's one of my favorite lenses. I am however very OCD and paranoid with my photo equipment. I also have an untrained eye when looking for such things\. I also recently checked my Lentar 450mm f6.3 and looks to me like it might have some fungus or haze. Most of my newer lenses I keep in my camera bags but I have started to keep my older ones in a clear plastic box next to a window. They're all kept in a cool and dry place. All my adapted lenses are my dad's old lenses that I've been using for years. The only new one is my Celtic 135mm and I just ordered a Rokkor-X 300mm f4.5. Is there anywhere I can bring it to have a professional look at it? Or should I try to bring it to a local camera shop and hope someone there knows anything or cares? I'm mostly concerned about fungus moving to my other lenses. Thanks in advance and sorry for such a long winded question.
