As you can tell, both cameras feature different resolutions and different sensor sizes. The FZ100 using its tinier sensor will make getting shallower depth of field more challenging and the Pentax K-3 will deliver more detail with its extra 10MP. Greater resolution can also enable you to crop photos way more aggressively. The more aged FZ100 is going to be disadvantaged when it comes to sensor tech.
