Safeguard Your Cameras Cameras and lenses are very susceptible to moisture damage. Safeguard them in storage and in your camera bag. Moisture is the enemy of camera equipment because it causes rust, mildew, corrosion, and even nurtures the growth of lichens and mold.   Today’s digital cameras have delicate electronic circuitry which is susceptible to even trace amounts of moisture. Camera collectors know that older cameras have parts made of felt, cloth, leather, and water-soluble glue.These materials act like sponges, holding enough moisture to create an environment where something may eventually grow in your camera or lens.  Mold, mildew, and even lichens can actually feed on lens coatings as well. They create a spidery tracing on the surface of your lens elements, and eventually creep inside the lens! Even though lenses are made of materials that won’t absorb moisture, they need to be protected from a moist environment. You need to protect your camera gear from moisture no matter how old or new it is. It doesn’t take much moisture to cause damage. Our sealed silica get units dehumidify long-term storage and offer protection from sudden downpours or other water contact with cameras and lenses. They fit neatly in your camera bag, they’re inexpensive and they absorb moisture effectively. When the color indicator shows that the unit is saturated, pop it in the oven to bake out the moisture, and put it right back in your camera bag. **** 4 out of 5 Hydrosorbent Silica Gel for camera travel, A customer from Pennsylvania. “Purchased 2 of these units for use on a recent trip to Borneo. Needed to protect Nikon DSL from excessive humidity when not being used. Placed camera in waterproof bag with the silica gel pack inside and sealed the unit. Worked great.” "This is just what I need for my camera equipment and especially what I need for my telescope after a night of observing." D. Quick
