Olympus TG-2 iHS vs Pentax K-S1 Sensor Comparison

		

		

			
Typically, its tough to visualize the contrast between sensor measurements just by looking at a spec sheet. The visual below should provide you a stronger sense of the sensor sizing in the TG-2 iHS and K-S1.
As you can see, the 2 cameras come with different megapixel count and different sensor measurements. The TG-2 iHS because of its tinier sensor is going to make getting bokeh trickier and the Pentax K-S1 will give you extra detail due to its extra 8 Megapixels. Higher resolution will enable you to crop shots a good deal more aggressively. The older TG-2 iHS is going to be disadvantaged when it comes to sensor technology.
