A simple rain sleeve is a practical solution. These lightweight covers are made to go over the camera and lens while you’re shooting, helping keep rain and snow off the body and lens barrel without preventing use of the controls. They’re inexpensive and especially useful for non-weather-sealed gear.

Weather sealing helps, but it’s still wise to keep moisture off the camera whenever possible. A rain cover or sleeve is the most direct way to protect the gear during use, rather than only before or after shooting.
