Olympus E-PL1s vs Pentax K-5 IIs Sensor Comparison

Quite often, its difficult to picture the contrast in sensor dimensions merely by going through specifications. The image underneath will help provide you a better sense of the sensor dimensions in the E-PL1s and K-5 IIs.

Plainly, each of the cameras come with different resolutions and different sensor dimensions. The E-PL1s using its smaller sensor is going to make shooting shallower depth of field tougher and the Pentax K-5 IIs will provide extra detail using its extra 4MP. Greater resolution will also make it easier to crop images a good deal more aggressively. The more aged E-PL1s will be behind when it comes to sensor tech.
