Just curious, if you are in a position to decide ONE new lens for Nikon to produce, what would it be? I would have one vote for AFS 16-70mm f/2.8 IF-ED VR II. And it better be a 77mm thread size cos I am tired of getting new filters.
You might as well request for 12-70mm... That way, Nikon would have to drop 14-24 and 24-70 in one sitting... :bsmilie: But given a super UWA to medium zoom, I'd think the distortions are going to be weeeeeeeaaaally hard to control.
The sigma 200-500 f2.8 weighs in excess of 15kg, a theoretical nikkor 200-400 f2.8 cannot be that much way off I think. Hopefully by then Nikon might just head towards lowering weight of superteles like Canon's new lineup
