Actually I think with heat outside it might be more of the opposite, (especially in Denise’s case) taking a cool camera from an AC environment to a hot humid outside. Many AC’s have a de-humidifying effect, no moisture in the air when bringing a hot camera inside should mean less condensation inside than out.
That is true. Yesterday I stepped out of the A/C car and my glasses immediatly fogged up so I could not see a thing. The same is going to happen to you lenses that have exposed glass, cooled metal (camera body), etc.
