As you can plainly see, both of the cameras posses different megapixel count and different sensor sizing. The G1 with its smaller sensor is going to make shooting shallower depth of field trickier and the Pentax K-3 II will result in extra detail having an extra 12MP. Higher resolution will enable you to crop shots somewhat more aggressively. The older G1 will be disadvantaged with regard to sensor tech.
