Ah! You are quoting the specs. Those terribly nice people at Nikon are giving you the pixels, not the actual amount of information in the scan. Also when they say 48 bits, all they mean is that the file store data from each pixel using 48 bits. But what about the sensor dynamic range and the analogue to digital converter? In practice the 8000ED has a much lower dynamic range than implied by the 48 bits figure. (The Minolta 5400 is no better.) If you doubt what I say, have a Google for reviews.
