That's OK, it's only a Canon.

You total Pentax snob, you!
I wouldn't wish that one on any camera, even a Canon. I think filters can be useful in rough circumstances, but I'm not a huge fan unless I do have salt and sand blowing my face or something like. As for slipping on rocks? That camera would be in a padded, preferably water proof, gear bag until my feet were on steady ground. Forget the lens hood/UV filter bit. I don't think that either would help much if you fell on rocks or into a lake.
