Olympus 7040 vs Panasonic G3 Sensor Comparison

Typically, it is very tough to visualize the difference between sensor sizing simply by reading technical specs. The photograph here should give you a better sense of the sensor sizing in the 7040 and G3.

As you can tell, both of these cameras have got different megapixels and different sensor sizing. The 7040 using its tinier sensor is going to make shooting bokeh tougher and the Panasonic G3 will deliver greater detail because of its extra 2MP. Higher resolution can also enable you to crop photographs much more aggressively. The older 7040 is going to be disadvantaged with regard to sensor technology.
