I did read that microscope manufacturers are using slow release fungicides.

It does give one ideas. After cleaning the lenses, how about coating the inside of the body with a fungicide to prevent reinfection?

Warning : I have no idea if a commercial fungicide won't release anything (oil?, moisture?) that will screw up your lens anyway.

By request of stiuskr, here's one from my 11-months old SAL1680Z. You can read the full history here.



The pattern of this fungus is very different from everything I have ever saw. Whenever I saw fungus in my lenses, it either grew from the border of the glass or formed spots in very definite positions of the lens. In this case, it is spread throughout the second element in a quasi-periodic manner, as if it came from a lattice of spores.

Added info 06/24/2011: other Dyxum member has a lens that is suffering exactly the same issue. According to him, he already took the lens to a authorized service center and the fungus is forming between the two fused frontal elements, probably in the glue that joins them. I'm in southeast Brazil and he is in Australia, and we both have lenses with the dreaded S/Ns.
