Nikon D750 vs Pentax K20D Sensor Comparison

Typically, it is very difficult to picture the contrast between sensor dimensions just by going over a spec sheet. The pic below should give you a much better sense of the sensor sizes in the D750 and K20D.

As you can see, both cameras posses different megapixel count and different sensor dimensions. The D750 using its bigger sensor is going to make getting shallower depth of field easier and the Nikon D750 will deliver more detail with its extra 9 Megapixels. Higher resolution can also let you crop shots somewhat more aggressively. The newer D750 should have an advantage with regard to sensor tech.
