Pentax KF vs Sony A33 Sensor Comparison

		

		

			
Sometimes, it is very difficult to picture the contrast in sensor sizes only by viewing a spec sheet. The pic here should provide you a far better sense of the sensor sizes in the KF and A33.
As you can see, the 2 cameras enjoy the same exact sensor sizing but different megapixels. You should anticipate the Pentax KF to render extra detail because of its extra 10MP. Greater resolution will allow you to crop photos far more aggressively. The more recent KF should have an edge in sensor tech.
