I am going to take my DSLR on my honeymoon to Mexico in July and I am worried about the lens steaming up. When I was in Mexico a few years ago, I remember my point n shoot camera would fog up after I walked outside the hotel and turned on the camera. I think it was the fact I was going from an air conditioned area to the humid outside. So I would usually have to wipe the lens, to get the steam off. But I never had the proper wipes so I had to use my shirt or other soft cloth. I am worried about this happening with my DSLR. Any suggestions? Also, I have a UV filter over the lens. If I do get it to fog up, am I going to have to take off the filter, clean the lens, put the filter back on and clean the filter? Looking for some advice. Thanks!
