Pentax K-01 vs Pentax S1 Sensor Comparison

Generally, its difficult to visualize the gap in sensor sizes purely by checking out specs. The image here should give you a stronger sense of the sensor dimensions in the K-01 and S1.

All in all, both of those cameras come with different resolutions and different sensor sizes. The K-01 with its bigger sensor is going to make getting shallower DOF easier and the Pentax K-01 will produce more detail using its extra 2MP. Higher resolution can also allow you to crop photographs a good deal more aggressively. The fresher K-01 provides an edge in sensor tech.
