Olympus SP-620 UZ vs Pentax K-3 II Sensor Comparison

Oftentimes, it is very hard to visualize the contrast in sensor measurements merely by viewing technical specs. The visual below may offer you a far better sense of the sensor sizes in the SP-620 UZ and K-3 II.

As you can tell, each of the cameras come with different resolutions and different sensor measurements. The SP-620 UZ with its smaller sensor is going to make achieving shallower depth of field harder and the Pentax K-3 II will provide you with greater detail having an extra 8 Megapixels. Greater resolution will make it easier to crop pics a good deal more aggressively. The older SP-620 UZ will be behind when it comes to sensor innovation.
