I'm after a super-wide for my D7200. The Tokina 11-20mm f/2.8 looks attractive, but I'm not too bothered about the 20mm coverage. So maybe the older 11-16mm would do just as well? I'm likely to get a 17-50mm f/2.8 too at some future date. Has anyone experience with either or both of these Tokina lenses? Or should I consider something else? At the moment I'm just going on published reviews. I like the build-quality of Tokina lenses, but so far haven't been too impressed with the optical quality of any of them. The push-ring AF/M switching I find irritating as well, but I'm willing to put up with it if the IQ is good. I've pretty much ruled out the Nikon 10-24mm f/3.5~4.5 because of its variable aperture and price. I'd rather have a constant aperture zoom and keep the cost below £500 UK ($750 US).
