Panasonic G3 vs Pentax K-1 Sensor Comparison

Sometimes, it's difficult to visualise the contrast in sensor sizing just by going through a spec sheet. The visual below should give you a stronger sense of the sensor dimensions in the G3 and K-1.

Clearly, both of the cameras come with different megapixel count and different sensor sizing. The G3 because of its smaller sensor will make getting shallow depth of field more difficult and the Pentax K-1 will produce greater detail having its extra 20 Megapixels. Higher resolution will also make it easier to crop shots a good deal more aggressively. The older G3 will be behind with regard to sensor innovation.
