Olympus E-420 vs Pentax K-50 Sensor Comparison

Normally, it's difficult to envision the contrast in sensor dimensions simply by viewing specifications. The pic underneath may provide you a more clear sense of the sensor sizing in the E-420 and K-50.

Plainly, both of the cameras enjoy different megapixel count and different sensor dimensions. The E-420 due to its smaller sensor will make achieving shallow DOF more difficult and the Pentax K-50 will render extra detail due to its extra 6MP. Greater resolution will enable you to crop images far more aggressively. The more aged E-420 will be disadvantaged when it comes to sensor technology.
