Pentax K-x vs Pentax K10D Sensor Comparison

More often than not, it is very difficult to visualise the difference between sensor measurements merely by checking technical specs. The visual below will help offer you a stronger sense of the sensor sizes in the K-x and K10D.

As you can tell, both the cameras offer the same exact sensor sizing but not the same resolution. You can anticipate the Pentax K-x to give extra detail having an extra 2MP. Greater resolution will allow you to crop photos a little more aggressively. The newer K-x will have an edge with regard to sensor tech.
