I have a Panasonic Lumix DMC-FT10 "tough" camera. I got it as a backup camera and to use for underwater and in bad weather, etc. Plus it's easier to carry around all the time than the dslr.
On occasions I have noticed that some condensation forms on the inside of the lens and I've now noticed there seems to be a blemish in the lens, like that is left from water when it dries out. I've cleaned the lens on the outside to no effect so I am thinking it must be on the inside.
I was wondering if anyone has taken apart a camera like this to clean the lens or anything like that and if doing so would affect it's waterproof capability. I think as long as it's carefully put back together with all the seals in place and the screws tightened enough then it should be okay but wanted to ask for opinions before I did anything.
