Pentax K-7 vs Pentax K-S1 Sensor Comparison

		

		

			
Typically, it is hard to imagine the contrast in sensor sizing merely by researching a spec sheet. The graphic here should offer you a greater sense of the sensor sizes in the K-7 and K-S1.
Clearly, both of those cameras offer the same exact sensor sizing but different MP. You can anticipate the Pentax K-S1 to provide you with greater detail as a result of its extra 5MP. Greater resolution can also enable you to crop photos a little more aggressively. The older K-7 will be disadvantaged in sensor tech.
