Olympus Tough-3000 vs Pentax 645Z Sensor Comparison

Usually, it is very hard to picture the contrast in sensor measurements purely by seeing a spec sheet. The photograph below should offer you a much better sense of the sensor sizing in the Tough-3000 and 645Z.

Clearly, both of the cameras have got different megapixel count and different sensor measurements. The Tough-3000 featuring a smaller sensor is going to make shooting shallower DOF more challenging and the Pentax 645Z will provide more detail due to its extra 39MP. Higher resolution will enable you to crop photographs much more aggressively. The older Tough-3000 will be behind with regard to sensor technology.
