Canon G5 X vs Pentax K-3 Sensor Comparison

More often than not, its difficult to visualize the contrast in sensor sizing merely by going through a spec sheet. The photograph underneath will help provide you a far better sense of the sensor dimensions in the G5 X and K-3.

As you can see, each of these cameras come with different resolutions and different sensor sizing. The G5 X because of its smaller sensor is going to make getting shallower depth of field tougher and the Pentax K-3 will show more detail due to its extra 4 Megapixels. Higher resolution will also make it easier to crop photographs a good deal more aggressively. The more recent G5 X should have an edge with regard to sensor technology.
