Hello everybody! I started this summer with digging out my fathers old photo equipment to try analogue photography. When I checked the lenses looking for fungus, I noticed that many of them are unfortunately affected. The above mentioned 180 mm-600 mm aswell. When I did a bit of research about fungus I realised that it's almost always cheaper to just buy a used lense from eBay since the old Nikor lenses became dirt-cheap over the years. But I was wondering what's about the 180mm-600mm lense? I've read some where that there weren't that many made of the lense, so I was wondering if it would be worth it to send it to a repairman for a clean up. The lense has fungus on multiple inner elements. How much would a clean up approximately cost? Or is it aswell a case of "just buy a used one from eBay"? Is the number of produced lenses of that type really relativly small? (I think I've read something around 1000) Tanks for any replies, with best regards KooperChaos.
