Panasonic GF3 vs Pentax K-3 II Sensor Comparison

Generally, it can be difficult to visualise the gap in sensor dimensions purely by viewing specifications. The picture here may provide you a far better sense of the sensor sizing in the GF3 and K-3 II.

Plainly, each of these cameras come with different megapixel count and different sensor dimensions. The GF3 with its smaller sensor will make shooting shallow depth of field trickier and the Pentax K-3 II will provide you with greater detail having an extra 12 Megapixels. Higher resolution can also allow you to crop pictures a good deal more aggressively. The more aged GF3 will be disadvantaged with regard to sensor technology.
