Nikon S8100 vs Pentax WG-3 Sensor Comparison

Typically, it is very tough to imagine the gap between sensor sizes merely by looking at specs. The image here may offer you a more clear sense of the sensor sizes in the S8100 and WG-3.

As you can plainly see, both cameras offer the same exact sensor sizing albeit different resolution. You should expect the Pentax WG-3 to resolve more detail because of its extra 4 Megapixels. Higher resolution will also make it easier to crop shots a little more aggressively. The more aged S8100 is going to be disadvantaged in sensor innovation.
