Panasonic GF8 vs Pentax K20D Sensor Comparison

Quite often, its hard to visualise the gap in sensor sizes only by seeing specs. The image here might offer you a better sense of the sensor dimensions in the GF8 and K20D.

As you can plainly see, the two cameras have got different resolutions and different sensor sizes. The GF8 due to its smaller sensor will make getting shallower depth of field harder and the Panasonic GF8 will produce more detail having its extra 1MP. Higher resolution can also let you crop pictures much more aggressively. The newer GF8 is going to have a benefit with regard to sensor technology.
