For sure. Condensation fucks shit up, at least it has for me in the past. I'd recommend not bringing your cam inside until you're done filming. Maybe only film after lunch, or eat outside. Personally, I don't take chances with condensation, and I usually just forget about my camera for a couple hours after bringing it in.
Its just the water inside the camera on the cold parts. It'll go with time, but you don't want to have those parts functioning with water inside.
At least for video, you'll know if you're fucked because it'll drop frames.
everything that needs to be known has been said.
