Pentax K-5 IIs vs Pentax K-S1 Sensor Comparison

		

		

			
Typically, its hard to visualize the contrast in sensor sizing purely by checking out a spec sheet. The photograph here will provide you a much better sense of the sensor measurements in the K-5 IIs and K-S1.
Clearly, the 2 cameras feature the identical sensor size albeit different resolution. You can count on the Pentax K-S1 to produce more detail because of its extra 4MP. Higher resolution will help you crop pictures way more aggressively. The older K-5 IIs will be disadvantaged in sensor technology.
