Keep your gear dry. Especially your lenses.

Humidity is the enemy of optics and electronics. Here's a weapon to help Canon and Nikon DSLR owners fight back.
Photographers have to be aware of condensation on lenses when moving from a cold to a warm environment—a common problem during the cold winter months—and must protect their sensitive electronics and optical lens elements when living or working in humid conditions such as rainforests and other tropical locales. Fortunately, BRNO has come up with a clever solution for Nikon and Canon DSLR owners that is available at Adorama.
Order the BNRO dri+Cap Dehumidifier cap for Canon or Nikon cameras and lenses at Adorama.
While keeping silica gel packs in your camera bag can help, BRNO has developed a Dri+Cap Dehumidifier Cap System for controlling humidity and moisture. The system consists of lens and body caps to fit Nikon and Canon DSLR bodies and interchangeable lenses that BRNO says will maintain a relative humidity of 35 to 45%, an acceptable range.
A silica gel packet, sealed in specially designed caps, has a color indicator that tells you when humidity levels get to high. The packet absorbs moisture only when attached to the camera or lens, drawing humidity away from the sensitive glass and electronics. Unlike some silica gel packs, the BNRO gel is in a sealed bag that does not give off dust particles—an important feature for digital photography where there is always a concern that dust could land on a camera's sensor.
The dri+Cap consists of a body cap and a rear lens cap, plus 8 foil-sealed packs of the color indicating silica gel. At the Adorama price of $44.99 it is a good investment for Nikon and Canon owners who are concerned about humidity.
