To sum up, the 2 cameras come with different megapixels and different sensor sizing. The GF3 due to its tinier sensor is going to make shooting bokeh harder and the Sigma Quattro will offer you greater detail as a result of its extra 17MP. Greater resolution will let you crop photos a good deal more aggressively. The older GF3 is going to be behind when it comes to sensor tech.
