Clearly, both the cameras have got different resolutions and different sensor measurements. The G3 due to its smaller sensor is going to make achieving shallow depth of field harder and the Panasonic G3 will show extra detail as a result of its extra 1 Megapixels. Greater resolution will also allow you to crop images much more aggressively. The younger G3 provides an edge in sensor technology.
