Bernie,

Fungus frequently damages the lens coating and the elements require replacing. Please phone the Mamiya UK service centre on 01782 753345, for some idea of price, but they will probably want to see the lens before they quote.

I have an RZ 180mm lens which has traces of fungus inside, on one of the two rearmost elements. Is DIY cleaning possible on this? Roughly how much would it cost for professional cleaning?
