    [QUOTE=thoongeng;7955953]yes I would also suggest TS get it checked at CSC




    so theoretically in a dry cabinet where conditions are not conducive fungus from one lens doesn't really 'spread' to others?
    read a few times people saying don't put an infected lens in dry cab to avoid spreading...[/QUOTE

    It doesn't spread... the spores are already in the air.

    There is the lens fungicide from Japan you can use. There is a CS thread quite sometime ago.

    Fumigation with potassium permanganate and potassium hydroxide? :-P

    It should destroy anything living. It's a strong oxidative reaction. Not 100% effective with spores though.

    Btw, before someone actually tries it, this process of fumigation might be harmful to the lens coating and components due to the high oxidative potential.

    Try UV-C light... only safest way to kill spores n fungus. Not uv-a/b.

    Just realised today one of my canon zoom lens is infected with fungus on the front and back element. What should I do next? Get it cleaned by CSC or scrap the lens all together?
    1) Use it as special soft focus lens without any need to buy soft focus filter.

    2) Scrape off some of the fungus and research under microscope. You may discover cure for some disease and win the next Nobel prize for medicine.
