Haze and Fungus (Cooke Speed Panchro)

[Robbie Fatt]

Hi,

I'm in the process of buying some used Cooke Speed Panchro lenses and have found that a lot of the available ones have haze and fungus.

How difficult is haze and fungus to remove from a Cooke Speed Panchro lens, and are there services which would do this? How much would they cost? I'm located in Sydney, Australia.

 

Any help would be much appreciated!!

Dom Jaeger would probably be able to give you the most detailed answer you’re likely to get, but basically both haze and fungus can be cleaned from the glass. The problem is that sometimes the fungus has eaten into the coatings, and will leave its own shape etched into the glass even after it’s removed. With something as expensive as a speed panchro, you’d want be sure how bad it was before you parted with any money.
