Pentax K-x vs Pentax KF Sensor Comparison

Usually, it's hard to see the contrast between sensor sizes purely by reviewing a spec sheet. The image underneath may provide you a far better sense of the sensor dimensions in the K-x and KF.

As you can see, each of these cameras come with the identical sensor size albeit not the same megapixels. You should count on the Pentax KF to offer you extra detail utilizing its extra 12MP. Higher resolution can also allow you to crop pictures a good deal more aggressively. The more aged K-x is going to be disadvantaged when it comes to sensor innovation.
