The 14-24 is fairly sharp at f/2.8, cleans up nicely at f/4, and improves its contrast a bit to f/5.6.
The 16-35 is a bit soft at f/4, no match for the 14-24, but cleans up nicely at f/5.6, yet still requires f/8 to raise the contrast in the upper areas, and never quite gains the crispness of the 14-24.
The 17-35 looks quite smeared at f/2.8, but as usual cleans up nicely at f/4, then continues to improve to f/11 in the upper areas.
