Hi Sam, The noise increases (both between the sensor elements, and within a single sensor element) with smaller sensor element geometry/spacing. Optically, a physically smaller CCD array, with the same sensor count as a larger one, requires higher resolution lenses than the physically larger CCD array would. Physical size/weight can effect the images as well. For long shutter speeds you are better off with a heavier camera, which is why the M camera does well in low light situations. If all you want is small images, like 4x6, yes, an APS sized sensor will give you some decent results...but as this is a Leica group, my guess is you must want more quality than that offers ;-) Austin - -- To unsubscribe, see http://mejac.palo-alto.ca.us/leica-users/unsub.html
