I'm on vacation at Disney World this week and I have a problem. I brought my Rebel with my 24-105mm and a rented 16-35mm. I've been using the rental almost exclusively and my 24-105 has been sleeping in my bag. Today I needed some reach so I went to switch and I noticed droplets of water all over the 24-105 and its fogged up pretty badly. It seems to be inside the lens the front and rear elements and UV filter look fine.
I am in a panic, everything I've read about this points to a universally bad ending. Is there anything I can do? I'm in the parks for the rest of the day today, then going straight to airport for my flight home. I am using resort transport so I'm not going to be able to get anywhere else really. If the lens needs servicing will the warranty cover it?
I'm screwed aren't I?
