Pentax Q7 vs Sony W550 Sensor Comparison

More often than not, it is hard to picture the gap in sensor sizing simply by going through a spec sheet. The visual here will offer you a greater sense of the sensor dimensions in the Q7 and W550.

Clearly, both of the cameras feature different megapixels and different sensor sizing. The Q7 with its bigger sensor is going to make achieving shallow depth of field easier and the Sony W550 will show more detail using its extra 2MP. Higher resolution will also let you crop photographs way more aggressively. The younger Q7 should have an advantage with regard to sensor tech.
