As you have seen, each of the cameras offer the same exact sensor sizing but not the same MP. You should anticipate the Panasonic G1 to provide greater detail having its extra 4 Megapixels. Greater resolution will also make it easier to crop photos a little more aggressively. The older E-300 will be behind in sensor tech.
