All, I am getting married in Puerto Aventuras, Mexico this August. I fully expect it to be very hot and humid. I am still a newbie in photography and I have not seen shooting in this type of climate. As I am letting someone use my camera to take shots of the wedding....so I have a few questions. My questions are: 1) Will I have a problem with moisture on my lens esspecially if I move the camera from indoors to outdoors and vice versa (the rooms will be air-conditioned, but we will be getting married on the beach)? 2) Is there anything I can do to prevent condensation on the lens (chemical treatments, simple tricks, etc.)? 3) Should I just have a cleaning cloth around to wipe and shoot...wipe and shoot...? I shouldn't have a problem applying a treatment to the Hoya UV lens I have on the camera, but I would be weary of applying anything to the main glass. Thanks guys!
