Olympus TG-3 vs Pentax Q7 Sensor Comparison

		

		

			
Oftentimes, it is very hard to picture the gap between sensor sizes simply by reading technical specs. The image below will help give you a clearer sense of the sensor measurements in the TG-3 and Q7.
As you can tell, the two cameras feature different megapixel count and different sensor sizes. The TG-3 featuring a tinier sensor is going to make achieving bokeh harder and the Olympus TG-3 will deliver more detail having its extra 4MP. Greater resolution will help you crop photos way more aggressively. The newer TG-3 provides an advantage with regard to sensor technology.
