    fungi feeds on organic material to grow. they do not derive much from the glass coating or the glass but live off organic contamination like oil films or dust on the lens surfaces. the older lenses may contain a cement which is a naturally derived material containing impurities to join the lens elements together. the fungi form webs of white fibures which penetrate into the infected item where they secrete enzymes to digest the material they feed on. often these acids will attack the coatings on the lens surface. fungi also require a certain level of moisture in order to grow. so they can synthesise the water from the oxygen in the air and hydrogen from the organic material. without moisture spores cannot germintate.

    kayheem - it is definitely not outside, i have tried wiping it away with cloth and e2 solution, not vanishing, and it should be below the surface based on eye.

    pokiemon - yes, i read that i should do that...... london weather next few days:

    Knowing UK weather this time of the year... not much sun dude.

    Looks like the fungus is just starting to grow. You might want to try disassembling the lens and cleaning it yourself? Since it is not expensive anyway.

    Ziploc with silica gel, by the window to catch some sun. That might work better.

    hrmmmmmmm. well, the heater's on, so that means humidity in the room will be low.

    the sun though, that's the problem. i was expecting to shoot tomorrow, we haven't had sunshine since last week one day, where i managed to grab maybe 2 or 3 shots. running dry for apad soon...........

    ahhh.. APAD... I have not even contemplated starting one for the new year. Haven't shot seriously in a while now except for my recent trip. Maybe it is time to start it up again.

    As Jed and Pokiemon mentioned, you can try killing the fungi with enough exposure to UV but it wont clean the stain left behind

    hmmm, looks inconclusive on effect of uv

    especially with that microbiologist's opinion.

    You did not sent to AVA for quarantine. Now that you have imported fungus, must pay $12 for AVA inspection. Next time tell the seller must apply for phyto cert too.
