lens fungus and sunlight

[sfcole]

I've seen a few people swear by subjecting their lenses to sunlight to kill fungus. I'm not worried about the

heat because of the time of year.

 

My question is: do you actually see a reduction of the fungus? My Leitz Elmarit 2.8 135 is really infested--

I can see filaments all through the lens, including a big spot. There also appears to be filiments on the

viewfinder goggles. I was going to send it to DAG for cleaning, but if I could get rid of a lot the fungus I'll

hold off.

Even if you do "kill" it, I'm sure the residue will remain....

I doubt that sunlight will fix it, but it's free to try!

 

Obviously if the fungus has actually etched into the coating or even the glass itself (which it will do in time), you can't "cure" that by exposure to sunlight.

Another kind of fix, originally proposed for 'yellowing' of Takumars with radioactive rare earths, will also work for lenses with fungus:

sorry, but I DO so love this solution to the problem.

JDM, I was laughing so hard I think I yellowed my underwear.;-)

that's a crime in some states! and smashing a lens is questionable also.
