Panasonic ZR1 vs Pentax K20D Sensor Comparison

Sometimes, it is very difficult to envision the contrast between sensor sizing purely by reviewing specs. The photograph here will offer you a much better sense of the sensor sizing in the ZR1 and K20D.

As you can plainly see, both cameras offer different megapixel count and different sensor sizing. The ZR1 because of its tinier sensor will make getting shallow depth of field more difficult and the Pentax K20D will offer greater detail as a result of its extra 3MP. Higher resolution will also enable you to crop pictures a little more aggressively. The younger ZR1 will have an edge in sensor technology.
