Pentax Efina vs Pentax K20D Sensor Comparison

Typically, it is hard to picture the gap in sensor dimensions just by looking through technical specs. The pic here will provide you a far better sense of the sensor sizing in the Efina and K20D.

As you have seen, both the cameras have got different megapixel count and different sensor dimensions. The Efina featuring a smaller sensor is going to make achieving bokeh harder and the Pentax K20D will provide you with greater detail having its extra 1MP. Greater resolution will enable you to crop photos much more aggressively. The more recent Efina should have an advantage when it comes to sensor technology.
