Nikon P100 vs Pentax K-x Sensor Comparison

More often than not, its tough to envision the difference between sensor measurements simply by looking at technical specs. The graphic here may give you a better sense of the sensor sizing in the P100 and K-x.

As you can tell, both of those cameras come with different resolutions and different sensor measurements. The P100 with its tinier sensor will make shooting shallow depth of field more challenging and the Pentax K-x will give more detail having an extra 2MP. Higher resolution can also make it easier to crop shots a good deal more aggressively. The more recent P100 will have a benefit when it comes to sensor technology.
