I already have the Tokina 12-24, and I find it to be a well corrected lens and sharp. Built IMO better than the Nikon 12-24. So these new offering should be interesting: http://bobatkins.com/photography/reviews/tokina_PIE2006.html I have heard rumors that Tamron is going to offer a 50-150 range f2.8 zoom this fall. So I might just wait. Yes, I have the Nikon 18-200VR that I am very happy with it. It is a great travel lens. Yet I have been wanting to get some faster lenses though. I like DOF control. Looks like the DSLR has finally matured for some great 3rd party offerings.
