Canon 17-55 F/2.8 IS anyone ???

But the reason is that when illuminating an image plane from the angles of a 17mm wide end with fidelity across the whole image, one is either::

a) weight limited

b) max FL limited

So, if you were willing to spend (let' just say lots) and carry around a 4 pound lens, it would be fairly easy to give you what you want,

Otherwise, one ends up being max FL limited.

To go from 16-35 to 16-50 would require about 4 more lenses (lens elements), or 3 more with one more asphere.
