Olympus TG-850 iHS vs Pentax K-x Sensor Comparison

		

		

			
More often than not, it's difficult to see the contrast in sensor sizing purely by viewing a spec sheet. The photograph here may provide you a stronger sense of the sensor measurements in the TG-850 iHS and K-x.
Clearly, the 2 cameras posses different megapixel count and different sensor sizing. The TG-850 iHS having a smaller sensor will make getting bokeh more challenging and the Olympus TG-850 iHS will provide you with extra detail using its extra 4 Megapixels. Higher resolution will also help you crop pictures somewhat more aggressively. The more recent TG-850 iHS is going to have a benefit with regard to sensor tech.
