Pentax Q-S1 vs Ricoh GXR A12 50mm F2.5 Macro Sensor Comparison

		

		

			
Typically, it is difficult to imagine the contrast in sensor dimensions purely by researching a spec sheet. The image here might offer you a clearer sense of the sensor measurements in the Q-S1 and GXR A12 50mm F2.5 Macro.
Clearly, each of the cameras enjoy the same exact megapixels but different sensor dimensions. The Q-S1 contains the smaller sensor which will make achieving shallow depth of field more difficult. The newer Q-S1 provides an edge when it comes to sensor technology.
