Pentax K-r vs Pentax K20D Sensor Comparison

Normally, it is difficult to visualise the contrast in sensor dimensions only by looking through specs. The picture underneath should offer you a far better sense of the sensor measurements in the K-r and K20D.

As you can plainly see, both the cameras posses the exact same sensor measurements but not the same resolution. You can expect to see the Pentax K20D to result in more detail as a result of its extra 3 Megapixels. Greater resolution can also let you crop photos somewhat more aggressively. The younger K-r is going to have an advantage with regard to sensor technology.
