Re: Lens Fungus

Fungi need humidity. I store my lenses in an airtight 'B&W' ('Peli' type) case with about 400 grams of activated silica gel. The silica gel has an indicator and as soon as it starts to 'turn' I reactivate it.

You need lots of silica gel and it needs to be in an airtight container. The tiny sachets you get with many consumer items are useless because they're far too small and probably have long been exhausted by the time they are used.

For removal of fungus look at post #12 here:

Forget exposure to UV/sunlight (unless the fungus is on the outside), 'normal' lens glass is not very transparent to UV.
