Panasonic G1 vs Panasonic ZS20

Here, we will be evaluating the Panasonic G1 and Panasonic ZS20, former being a Entry-Level Mirrorless while the latter is a Small Sensor Superzoom and they are both offered by Panasonic. The sensor resolution of the G1 (12MP) and the ZS20 (14MP) is pretty close but the G1 (Four Thirds) and ZS20 (1/2.3") boast different sensor sizes.

The G1 was revealed 4 years before the ZS20 and that is a fairly significant difference as far as camera tech is concerned. Both of these cameras feature different body design with the Panasonic G1 being a SLR-style mirrorless camera and the Panasonic ZS20 being a Compact camera.

Before going right into a complete comparison, here is a short summation of how the G1 matches up against the ZS20 in relation to portability, imaging, features and an overall grade.

Oftentimes, it's hard to picture the gap in sensor measurements only by viewing specs. The graphic here might provide you a far better sense of the sensor sizes in the G1 and ZS20.

All in all, the two cameras come with different megapixel count and different sensor measurements. The G1 having a bigger sensor is going to make getting shallower depth of field less difficult and the Panasonic ZS20 will provide you with extra detail because of its extra 2 Megapixels. Higher resolution can also make it easier to crop shots a good deal more aggressively. The older G1 will be behind with regard to sensor technology.
