Prevent Lens Fog

[gonzo]

On Sunday I was hiking up Neff's Canyon, and my lens kept fogging up whenever I would pull it out my camera bag. Any suggestions on how to prevent this?

were you keeping it in a bag that was warm? perhaps close to your body? the key is to keep the camera near the same ambient temperature as outside. when the cold camera touches warm air, it condenses. so if the camera is cold, and you put it next to your warm body... fogs up.

Eat lots of ice to decrease your body temperature :five:
