Olympus E-620 vs Pentax K100D Sensor Comparison

Normally, its hard to imagine the contrast in sensor sizing simply by viewing specifications. The visual here might provide you a greater sense of the sensor dimensions in the E-620 and K100D.

To sum up, both of the cameras provide different resolutions and different sensor sizing. The E-620 having a smaller sensor is going to make shooting shallow DOF harder and the Olympus E-620 will provide you with more detail because of its extra 6MP. Greater resolution can also help you crop photos more aggressively. The fresher E-620 should have an edge when it comes to sensor innovation.
