Panasonic G2 vs Pentax Efina Sensor Comparison

Usually, it is tough to picture the contrast in sensor measurements just by viewing specifications. The photograph here might give you a much better sense of the sensor dimensions in the G2 and Efina.

Plainly, both cameras come with different megapixel count and different sensor measurements. The G2 using its larger sensor is going to make achieving shallower depth of field less difficult and the Pentax Efina will provide you with extra detail with its extra 2MP. Greater resolution will enable you to crop photos a good deal more aggressively. The older G2 will be disadvantaged when it comes to sensor innovation.
