Panasonic GF3 vs Pentax K100D S Sensor Comparison

Sometimes, it's difficult to visualize the gap in sensor sizing purely by looking through specifications. The photograph underneath should offer you a stronger sense of the sensor dimensions in the GF3 and K100D S.

Plainly, both of these cameras posses different megapixel count and different sensor sizing. The GF3 using its smaller sensor is going to make shooting shallower depth of field tougher and the Panasonic GF3 will result in greater detail because of its extra 6 Megapixels. Greater resolution will make it easier to crop photos somewhat more aggressively. The more modern GF3 provides an advantage with regard to sensor innovation.
