 Why are these so heavy? Obviously, there's lots of metal and glass there
because they're big lenses, but I guess my question then is 'does more glass
make a better lens'?

 I know that you need a bigger front opening to let more light in to make
the lens faster, but the Series 1s aren't super-fast; does all the glass
help to correct for aberrations or something?
