Bob: : OK, that's a good enough real-world reason. But too it's no reason to stop "campaiging" against the idiocy of such "50 Mb" requirements. : : At the camera level the dumbest of all (hello Fuji) are those cameras that digitally extrapolate upwards to produce bloated file sizes / higher pixel dimensions. The reason (picking through all the spin) was that customers had come to ask solely about output pixel resolutions instead of the sensor ones. first question asked whenever anyone looks at a camera in the shop: "how big a file can it output" I sigh.. then go through the explanation. it's the same with scanners too of course k
