start getting additional features like seals to keep out dust and water. The Rebel is probably pretty well protected although not as much as a 5D for example. There are 'bags' available to protect them from rain. Basically, they are kept enclosed except for a lense opening.
They are NOT all destined to malfunction, but water in any electonic device is a problem. Her camera may come back to life after it dries out thoroughly. Note that ALL cameras these days rely on electronics.
I have a Canon Digital Rebel XT and love it. Recently my sister bought a digital camera (not an SLR; not sure which brand) for her vacation to New Zealand. Halfway through the trip after a wet hike, the camera stopped working. The camera had never been submerged in water and she'd been careful about letting it get too wet from the rain. She brought it to a repair shop and the guy there said it was an extremely common problem with ALL digital cameras.
She couldn't really explain to me what the actual problem was - can anyone figure it out from my description? What about using a digital camera in the rain - are all of them destined to malfunction when exposed to just a little bit of exterior water? I live in a humid climate and travel to a lot of tropical locations where I'd want to bring my DSLR. In rainy conditions, normally I'd wrap it in a plastic bag and only expose the end of the lens, but am I doing enough to protect it? I really don't want my $800 camera to be suddenly rendered useless.
