Pentax Q-S1 vs Sony A390 Sensor Comparison
Oftentimes, its tough to imagine the contrast in sensor sizes purely by going through specs. The pic here should provide you a better sense of the sensor sizes in the Q-S1 and A390.
All in all, both of the cameras posses different megapixel count and different sensor sizes. The Q-S1 with its smaller sensor is going to make getting shallower DOF more challenging and the Sony A390 will provide more detail using its extra 2MP. Higher resolution can also let you crop shots somewhat more aggressively. The younger Q-S1 should have a benefit when it comes to sensor innovation.
