DO any of you do any work (club guys) in really SMOKEY venues? With all that cigarette smoke floating in the air, do you think it takes a toll on the camera sensor or lenses at all? Any personal experience? It just kind of popped into mind of one of the things I would be apprehensive about doing. I can picture the sensor or lenses getting gunked up like the windows of a car with that cigarette smoke film that's left over and a huge pain in the cock to get off.
