Pentax K-r vs Pentax K100D Sensor Comparison

Quite often, it is hard to visualise the gap between sensor sizes purely by reviewing technical specs. The image here will provide you a more clear sense of the sensor measurements in the K-r and K100D.

As you can tell, both of the cameras enjoy the same exact sensor sizing but not the same MP. You should expect to see the Pentax K-r to offer more detail having its extra 6MP. Greater resolution can also let you crop images far more aggressively. The more recent K-r is going to have an edge with regard to sensor innovation.
