As you can see, each of the cameras provide different megapixels and different sensor sizes. The LX7 featuring a tinier sensor will make getting shallow DOF more challenging and the Pentax K-x will give you greater detail as a result of its extra 2 Megapixels. Greater resolution can also enable you to crop images more aggressively. The newer LX7 will have an edge in sensor tech.
