Olympus E-420 vs Pentax KP Sensor Comparison

More often than not, its tough to envision the gap in sensor sizing merely by going through specs. The visual here will help provide you a greater sense of the sensor sizing in the E-420 and KP.

All in all, the 2 cameras have got different megapixel count and different sensor sizing. The E-420 due to its smaller sensor will make shooting bokeh trickier and the Pentax KP will show greater detail as a result of its extra 14MP. Higher resolution can also make it easier to crop shots much more aggressively. The older E-420 will be disadvantaged when it comes to sensor tech.
