Safeguard Your Cameras

Cameras and lenses are very susceptible to moisture damage.

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.

                                        Excess humidity is destructive to cameras.


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.
