Having owned the 16-35, 17-40, 16-35 II in that order and I currently own the Nikkor 14-24G, I'd say the 17-40 is at the bottom of the UWA zoom pack in terms of absolute IQ. Can one make likable images with it? Of course. If I couldn't, that would be saying more about my abilities than the lens'. But let's be honest. The single best "feature" of this lens is price.
