New K5 owner. Lens suggestions.

Hello all,

I just picked up a K5 with the kit lens. I am looking for a good landscape lens that can get wet. I am a current Canon user and shoot with a 60D so the Pentax gear is new to me. I bought the K5 because of the water resistance and the better dynamic range. So far I am loving this camera. So much smaller then the 60D and a joy to use.

Thanks
--
