My take on the 24-105/4.0 is that 24mm is too wide.

Think about it: a 105mm f/2.0 lens would have a 53mm wide aperture. OK, the front element would be a bit larger (the 100/2.0 takes a 58mm filter). But the 105/4.0 takes a 77mm filter. That's because it has to do the extreme WA of 24mm.

So a 55-110/2.0 IS should be completely possible and only slightly larger than the 100/2.0, say a 67mm filter size.

Is the 70-200 / 2.8L "only slightly larger" than the 200 / 2.8L?
