Pentax K100D S vs Pentax E85 Sensor Comparison

In many cases, it can be hard to see the gap between sensor sizing purely by reading through specifications. The visual below will help give you a far better sense of the sensor sizes in the K100D S and E85.

Plainly, both of the cameras have different resolutions and different sensor sizing. The K100D S due to its larger sensor will make achieving shallow depth of field less difficult and the Pentax E85 will give extra detail as a result of its extra 6MP. Greater resolution will also allow you to crop photos a bit more aggressively. The older K100D S is going to be disadvantaged with regard to sensor technology.
