Both Tokina and Tamron are making excellent lenses. I have an older Tokina 17mm, not an excellent lens, but certainly passable. A friend has an older Tamron 17 that is very good indeed. I don't think that you would especially need an AF lens with this focal length, as at f/8 depth of field will be from within arms reach to infinity anyway, so all you really need to look for is a decent manual focus lens, preferably with an A setting, or if you can find an AF lens at a good price, then that would be good also.
