Canon SD940 IS vs Olympus TG-870 Sensor Comparison

		

		

			
Oftentimes, it's tough to imagine the gap in sensor sizes merely by looking through specifications. The pic here might provide you a more clear sense of the sensor sizes in the SD940 IS and TG-870.
To sum up, the two cameras provide the same sensor dimensions albeit different MP. You should expect the Olympus TG-870 to render more detail utilizing its extra 4 Megapixels. Higher resolution can also let you crop shots more aggressively. The more aged SD940 IS will be disadvantaged with regard to sensor tech.
