Olympus TG-310 vs Pentax WG-2 Sensor Comparison

		

		

			
Oftentimes, it's difficult to see the difference between sensor sizes just by reading through technical specs. The pic here might offer you a more clear sense of the sensor sizing in the TG-310 and WG-2.
As you have seen, both the cameras provide the same sensor dimensions but not the same MP. You should expect to see the Pentax WG-2 to give you extra detail having its extra 2MP. Greater resolution can also allow you to crop images more aggressively. The more aged TG-310 is going to be behind when it comes to sensor tech.
