Well, I think the K-30 is not the only camera that can be abused like that in a short period of time, someone else actually had done something similar on the K-5 previously (but yet almost no body noticed):-

Btw, if any user really wanted to have a waterproof camera, why not just get an Optio WG or to use an underwater housing? :-o
Enjoy after all!~
