Nikon D40 vs Pentax KF Sensor Comparison

Usually, it's difficult to visualise the contrast in sensor dimensions merely by looking through technical specs. The image here may provide you a much better sense of the sensor dimensions in the D40 and KF.

As you have seen, both of these cameras have the same sensor dimensions but not the same MP. You should expect to see the Pentax KF to result in greater detail due to its extra 18MP. Greater resolution can also enable you to crop images a bit more aggressively. The more aged D40 will be behind when it comes to sensor innovation.
