Typically, it's hard to visualise the gap in sensor dimensions purely by viewing technical specs. The picture here will help provide you a much better sense of the sensor sizes in the K-3 and H400.

As you can tell, both the cameras enjoy different megapixels and different sensor dimensions. The K-3 having a larger sensor will make shooting shallower depth of field less difficult and the Pentax K-3 will provide you with greater detail because of its extra 4MP. Greater resolution will let you crop photos far more aggressively.
