Someone who wants 2.8 instead of 4.0, I guess ... looks like we\'re giving away a full stop of light to get that smaller size.
I don\'t understand why you think that. The corresponding Canon lens with f/4 is larger and heavier. Are there any FF 24-70/4 zooms that are lighter and smaller than the FE?
I meant to go from 2.8 to 4.0 in general.
But, here is the corresponding Canon with IS. (I think I got the right one this time.)
83mm
93mm
600g
That makes the delta @ 1cm shorter and 170g lighter (sans IS).
