Then that same technology can be applied to larger sensors. I'm not saying that smaller sensors won't be good enough for certain applications or that they won't get better, just that *any* sensor, whether film or digital, can only capture the image information that's being projected onto it. This is why development of medium format digital hasn't stopped but is in fact accelerating. The advantages of a larger sensor area over a smaller one (whether that sensor be film of electronic) are the same when going from APS to 35mm, 35mm to MF or MF to LF. The very fundamental limits (wavelengths of light, diffraction limitations, etc.) won't be changing as pixels get smaller and noise gets lower. -- Mark Roberts Photography and writing www.robertstech.com
