At a shoot yesterday, my 5D caught a bit of condensation. I didn't notice during the shoot and the picture's weren't too badly affected. But today, when I pulled the camera out I'm getting Error 99 messages. When I looked up the error, I made sure nothing else was the problem (i.e., lens, battery, memory card, contacts, etc.) then someone wrote that condensation can cause error 99. I figured that must be the problem. So, what's the best way to let the body dry out? Right now I have the body on a desk with the cap off, but under a ziploc bag to help reduce dust that might drift in. Anything else I should do? And, on another note, how can I avoid condensation in the future? I thought I knew, but apparently I didn't.
