Panasonic GF7 vs Pentax K-x Sensor Comparison

In many cases, its tough to imagine the gap between sensor sizing merely by checking technical specs. The photograph here may offer you a stronger sense of the sensor sizing in the GF7 and K-x.

As you can tell, the 2 cameras have got different resolutions and different sensor sizing. The GF7 featuring a tinier sensor is going to make getting shallower DOF more difficult and the Panasonic GF7 will resolve more detail as a result of its extra 4MP. Greater resolution will also make it easier to crop pics much more aggressively. The more modern GF7 should have an advantage when it comes to sensor tech.
