Panasonic G9 vs Sony A390 Sensor Comparison

Quite often, it's difficult to imagine the difference in sensor sizing simply by looking through specifications. The visual here should provide you a far better sense of the sensor sizing in the G9 and A390.

Plainly, the 2 cameras posses different megapixel count and different sensor sizing. The G9 using its smaller sensor is going to make getting shallower depth of field more challenging and the Panasonic G9 will result in extra detail having an extra 6 Megapixels. Greater resolution can also allow you to crop photos somewhat more aggressively. The newer G9 should have a benefit with regard to sensor tech.
