I'm going to Genting tomorrow and I'm bringing the camera. Let's say I'm at the outdoor theme park and there's a shot I MUST take, so I need to switch lenses right there. Now, I'm rusty on the condensation part but would the inside of the lens fog up? And correct me if I'm wrong but there's a lot of moisture in the air up there right? That spells "danger" when changing lenses outdoors?
