As you can see, each of the cameras come with the identical sensor size albeit not the same MP. You should expect the Samsung ST100 to resolve greater detail due to its extra 2MP. Higher resolution will also make it easier to crop photographs a good deal more aggressively. The more aged P70 is going to be behind with regard to sensor innovation.
