Weather sealing is one thing, submersion quite another. Although I have heard of two instances where a K7 was accidentally submerged and survived. Not something I’d try.
However it's nice to be fearless in the face of the elements. There's been too many times where I had to quickly take cover with my Kx, but it's nice to have an unencumbered body with a selection of lenses and not to have to worry about pouring rain, snow, extreme cold, dust or sandstorms.
