All in all, both of these cameras posses different resolutions and different sensor measurements. The 5D MIII because of its larger sensor is going to make achieving shallower DOF easier and the Pentax K-3 will deliver extra detail as a result of its extra 2MP. Greater resolution can also enable you to crop pics somewhat more aggressively. The older 5D MIII is going to be behind in sensor innovation.
