>From astronomy I can tell you some differences. If the chip is smaller but the pixel count is the same the pixels are then smaller and often can yield finer detail if the choice of lenses is done correctly. That's why some people in the industry don't like the preoccupation with pixel count instead of pixel size and dynamic range. Often a smaller, better chip with less pixels can yield superior results over something larger. Kent Gittings

But isn't a smaller CCD equal to cropping with a larger CCD? As far as I can see, there are no advantage whatsoever with the smaller chip since you can always crop the image from a full size chip down to what would have been produced by the same chip but smaller.
