    Silica dessicant in the bag?

    Was an idea I had while shopping one day. Moisture is the enemy of lenses, it brings fungus and all sort of fun stuff with it, am I the only one who thinks this is a great idea? I have a couple in my Nikon bag and one in my Canon bag, all my Canon EF lenses are L's and have seals in them to prevent that stuff.

    How often do you recharge (dry out) the silica? To be effective, in a place as humid as Florida, I would guess that you would need to do this frequently for it to be of any use.

    Made sense to me too. I have desiccants everywhere--bags, lens cases. The only problem is that the covers wear out and leaves all that silica everywhere. Small price to pay to protect my gear.

    Tidy Cat Crystals in a perforated 35mm film container are a good solution. Drill a series of 1/8" holes in the sides, slip in a liner made from coffee filter material and fill it with Tidy Cat Crystals. The crystals are pure silica gel. It will hold a lot of moisture and won't fill your cases with particles. I have no idea what other brands of cat litter may be the same, but it's worth looking in to.

    I just bought cat litter for my babies, I'll have to look into it.

    Normal cat litter is very, very dusty. I believe the poster was referring to the kind that is all crystals.

    Since it seems that much of the small electronic and optical items come with those small bags, I think it's a great idea. Especially in humid areas. A cabinet with a "goldenrod" or even a small incandescent lightbulb is good for storage.

    But you do have to recharge (essentially bake out the moisture) every so often. There is indicator silica gel that changes color when it has lost its effectiveness.

    Dessicants really work best in a sealed bag or container; otherwise, they just soak up moisture from the environment and stop working.

    Yup, like this one:

    Gets the moisture out AND neutralizes that 'old musty camera' smell...you can't beat that!
