Olympus E-3 vs Pentax KP Sensor Comparison

Normally, it can be difficult to visualize the gap in sensor dimensions simply by checking out specs. The picture below will help offer you a greater sense of the sensor sizes in the E-3 and KP.

All in all, the 2 cameras provide different megapixel count and different sensor dimensions. The E-3 using its smaller sensor is going to make shooting shallower DOF trickier and the Pentax KP will provide extra detail using its extra 14MP. Higher resolution will also allow you to crop shots more aggressively. The more aged E-3 will be disadvantaged in sensor innovation.
