Hey,
I just got a Rolleiflex 2.8 F with lens fungus (from the internet, i'm stupid, i know)

The front element seams to be perfectly clean, but the rear element seams to be pretty badly "infected". Since I have little expirience with problems like that, I'd like to ask you how good my chances are this could be repaired, since I'm not too sure if the seller of this item will accept a return of the item. I hope he does since he stated that the lenses where in perfect condition.

thank you
