Pentax K-S1 vs Pentax Q Sensor Comparison

Normally, it is tough to visualize the contrast in sensor dimensions purely by seeing specifications. The pic underneath might offer you a far better sense of the sensor sizes in the K-S1 and Q.

Plainly, both of those cameras enjoy different resolutions and different sensor dimensions. The K-S1 with its bigger sensor is going to make shooting shallow depth of field simpler and the Pentax K-S1 will provide greater detail with its extra 8MP. Higher resolution will enable you to crop pictures far more aggressively. The newer K-S1 should have an edge with regard to sensor tech.
