Casio EX-H20G vs Pentax 645D Sensor Comparison
Often, it can be hard to visualise the difference in sensor dimensions simply by looking through a spec sheet. The pic here will offer you a clearer sense of the sensor measurements in the EX-H20G and 645D.
Clearly, the 2 cameras have got different megapixels and different sensor dimensions. The EX-H20G because of its smaller sensor will make achieving shallower depth of field more difficult and the Pentax 645D will provide you with greater detail as a result of its extra 26MP. Greater resolution can also let you crop pics much more aggressively. The more modern EX-H20G is going to have an advantage with regard to sensor tech.
