I have had mine in the "rain" a few times. Actually, it was only sprinkling, not a heavy rain at all. I've had it out during a light snowfall. No problems yet. I am not worrying about it. I purchased the extended warranty and if something happens, I will have them fix it. I'm not going to do anything stupid, but it is supposed to be weather resistant and I won't hesitate to use it if I need to.
When I have gotten it wet, I always leave the zoom extended (if applicable) once I get inside and let the camera set at room temperature for a good time before putting it away. I don't see how gently wiping it down with a microfiber towel would hurt anything. Definitely use a hood to protect the front element - certainly makes it easier to keep the water drops off.
