Pentax Q-S1 vs Sigma Quattro H Sensor Comparison

Oftentimes, it is very hard to picture the gap between sensor measurements purely by reading through a spec sheet. The photograph here might give you a stronger sense of the sensor sizing in the Q-S1 and Quattro H.

As you can see, the 2 cameras posses different resolutions and different sensor measurements. The Q-S1 with its tinier sensor is going to make shooting shallow depth of field tougher and the Sigma Quattro H will resolve greater detail having an extra 33 Megapixels. Higher resolution will let you crop shots somewhat more aggressively. The older Q-S1 is going to be disadvantaged with regard to sensor innovation.
