>>>Interesting.  Just how much lighter can a body be made by making the
mirror a
couple millimeters smaller?  Are we talking fractions of grams here?<<<

It's more a question of where the mirror has to go. It has to flip up
out of the way of the light from the lens. A mirror that is larger by
only a small amount can mean the body has to be quite a bit bigger, and
thus heavier.

It's a little like saying, "One sailboat is 38 feet long and one is 41
feet long. How much could three feet weigh?" But of course the entire
boat has to have larger proportions, so a slightly longer boat might in
fact be much larger (and more expensive).
