    You can either bring a digital body and take an see whether your picutres are affected, (ie signs of fungus on your picture) if not, just open the aperature and look through the lens. If there is fungus, you should be able to see in when you see through it, dark spots etc..

    Unmount the lens from the body and look into the lens. You should try to view the different pieces of glass elements within. Fungal growths should look whitish, like smudge stains but they look thready, spidery, like wisps of cloud. It is generally easier to spot them on a telephoto lens compared to a wide angle, especially for the internal elements, so if you're looking at a zoom lens, zoom to the telephoto end before checking.

    cheers

    .... to add, set your aperture to its largest (ie small f/number).

    though not very often preached, something which I usually practise myself is to turn the focusing ring from minimum to infinity focus while inspecting through the lens. This helps to identify the presence of fungus or even fine hair-line scratch.

    Hi,

    Do you know how much does it cost to clean the fungus infected lens? Is it worth the money and time to do the cleaning? Any places to recommend?

    Thank you.

    the fuss free method is to send it back to the original brand's customer service centre.

    If this fungus corrode into the lens coating or even the lens element itself, you will need to change that piece of lens. And that's not cheap!

    Hi do you know how to see whether the fungus is corrode into thelens coating or even the lens element itself by naked eyes? I can only see a few spider web like thing on the front lens. Thank you.

    Does the spider-web thing spread out like tiny little flow of streams all around it? If the answer is yes, not much hope.
