    I have been told that if a lens has fungus and is placed in a dry sunny place for a few days the fungus dissapears or is that an old wives tale?

    I think the theory is that the uv kills the fungus?????

    If this is a load of rubbish please be gentle with me!!!!

    Cheers Dave

    If the fungus has already etched the glass (which, by the time you notice it, it usually has), then you can kill and/or remove the fungus, but there is nothing that can be done about the damaged glass.
    This is the sad voice of experience speaking.

    UV will kill the fungus spores so it won't continue to grow, but it won't magically clean up what's already there. I've been wondering if a full-spectrum fluorescent bulb gives off the right UV wavelengths to kill it. Would periodic flooding under UV lamps be a good preventative measure?

    This is one of the best monographs on lens fungus that I have read. It has no references though. The writer is Gordon Ian Stalker BSc, who I believe is a camera technician rather than a mycologist.
