Disappointed with K-30.

All cameras that are not waterproof, will allow water vapor in, including the iphones and P&S cameras, you think are better.  The critical aspect is moving the camera from a colder environment to a warmer, humid one.  Moisture will not condense on a warmer surface.  If I have an iphone in my pocket and then take it out after it's warm, the water vapor will not condense on it near as readily.
