Panasonic 3D1 vs Pentax 645D Sensor Comparison

Typically, it's difficult to picture the contrast in sensor dimensions just by viewing specifications. The picture below may give you a far better sense of the sensor sizes in the 3D1 and 645D.

Plainly, each of the cameras feature different megapixel count and different sensor dimensions. The 3D1 featuring a smaller sensor is going to make getting shallow depth of field trickier and the Pentax 645D will provide you with more detail having its extra 28 Megapixels. Higher resolution will allow you to crop pictures way more aggressively. The more recent 3D1 provides an edge in sensor innovation.
