Pentax 645D vs Pentax K-r Sensor Comparison
More often than not, it's hard to picture the difference between sensor dimensions purely by reading through specifications. The picture underneath should provide you a clearer sense of the sensor sizing in the 645D and K-r.
Plainly, the 2 cameras have different resolutions and different sensor dimensions. The 645D using its bigger sensor is going to make getting shallow depth of field less difficult and the Pentax 645D will resolve more detail because of its extra 28 Megapixels. Higher resolution will enable you to crop photographs a bit more aggressively. The more aged 645D is going to be disadvantaged with regard to sensor tech.
