    I wonder at what point mold inside the lens begins to affect image quality.

    You might start to notice a decrease in contrast as the mold becomes more pronounced. The light will be diffused as it strikes the mold, which kills contrast.

    You're welcome. BTW: don't let the mold continue to grow. I've read that you can kill the mold with UV light. Sunlight might do it, but don't let the lens get warm. Maybe a UV lamp would be safer.

    I store my lenses in a plastic box with lid and I toss in those silica gel packets that come with new merchandise. Silica gel is supposed to absorb moisture, and I hate to simply throw those packets out.

    I 've heard you cab stop it growing with sunlight but not make what's there go away. I've also heard (maybe from you a while back) that Canon won't clean a moldy lens because they can't guarantee the work. I'm going to look into a large container that I can fit camera and lens into with silica gel.

    It wasn't me, but if anything, I would caution against any DYI lens repair.

    Thanks. No I wasn't going to attempt it. The lens in question is a Canon 400 5,6

    Could you not put them in a suitcase? Just buy twice the quantity of silica gel that you need and regularly dry the half that is not in the suitcase in the oven and then change it?
    I would put all your camera stuff there as I guess this could affect them all with the humid climate you have.

    Thanks Dave that is a good idea. I'm going to buy a quart of silica beads when I visit the states.

    Can't you buy them in Colombia? I know it can be complicated there but it should be possible.

    Should be but I wouldn't know where to start. Easy to find on US Amazon though.
