This may be a dumb question, but I have been meaning to ask it for a while. I live in Arizona so it gets pretty darn hot in the summer. I want to start taking my camera with me everywhere I go, but am worried about leaving it in the car for extended periods. Like if I go in to see a movie, or eat at a restaurant. Typically I would leave the windows cracked just to let SOME of the heat out, but it would still be an oven in the car. I have a T1i. Aside from fogging issues, would the heat pose a threat to the camera? Could it melt something inside like the sensor or some solder or something? What about on typical lenses?
