> Science missions use 2mp CCDs mostly because of the sensitivity It would be foolish to suggest there was a single motivator for inclusion of a sensor. In reality it is a combination of our answers. Large sensors allows lower gain and better noise performance, enables smaller aperture use at acceptable sharpness, takes less resources to process, transmit etc. You're not wrong in mentioning it though. Although FF at 25600 is going to be piss poor even if it's Nikon / Sony. edit: corrected stupid misspelling

You've got very high standards in image quality :-) Nikon D600 at 25600: http://www.imaging-resource.com/PRODS/nikon-d600/nikon-d600GALLERY.HTM http://www.imaging-resource.com/PRODS/nikon-d600/nikon-d600G... Not even close to "piss poor" in my book.

  That's about the noise level and sharpness I have on my EOS 40D with ISO 1600. I think I'm going to cry in a corner a little. That being said, you don't go that high unless you're very desperate and the sensor itself can go up to 6400, the rest is software.
