I have Nikkor 17-35 f/2.8 and I have been using it for years ... it works absolutely well and still performing like champ. Now, looking at the new AF-S 16-35 MTF chart, it kinda makes me wonder, whether I should sell the 17-35 and get the 16-35 f/4 instead?
So here is my question - if you were in my situation, what are some pros/cons that you will consider in making this decision? Or would you bit the bullet and jump to 14-24 instead?
