Pentax K-1 vs Pentax K100D S Sensor Comparison

Quite often, it is very tough to envision the gap in sensor sizes just by checking out specs. The picture here should provide you a more clear sense of the sensor measurements in the K-1 and K100D S.

As you can plainly see, both of these cameras come with different resolutions and different sensor sizes. The K-1 featuring a larger sensor will make achieving shallower DOF easier and the Pentax K-1 will provide more detail due to its extra 30 Megapixels. Greater resolution will enable you to crop pics a good deal more aggressively. The more recent K-1 is going to have a benefit in sensor technology.
