Canon D20 vs Olympus TG-4 Sensor Comparison

		

		

			
Quite often, its tough to see the gap in sensor sizing simply by checking out specs. The photograph here might provide you a better sense of the sensor dimensions in the D20 and TG-4.
As you can plainly see, each of the cameras enjoy the same exact sensor sizing but not the same megapixels. You should expect to see the Olympus TG-4 to produce more detail as a result of its extra 4 Megapixels. Greater resolution can also allow you to crop images far more aggressively. The older D20 will be disadvantaged when it comes to sensor innovation.
