Olympus TG-310 vs Pentax K-3

Below is a extended overview of the Olympus TG-310 vs Pentax K-3, one being a Waterproof and the other is a Advanced DSLR by manufacturers Olympus and Pentax. There exists a big gap between the sensor resolutions of the TG-310 (14MP) and K-3 (24MP) and the TG-310 (1/2.3") and K-3 (APS-C) boast totally different sensor dimensions.

Typically, it can be tough to envision the difference between sensor measurements merely by looking at technical specs. The graphic here might provide you a clearer sense of the sensor sizing in the TG-310 and K-3.

As you can tell, the two cameras come with different megapixel count and different sensor measurements. The TG-310 having a tinier sensor will make shooting bokeh harder and the Pentax K-3 will resolve greater detail with its extra 10 Megapixels. Greater resolution will allow you to crop pics a good deal more aggressively. The older TG-310 is going to be disadvantaged in sensor innovation.
