Photograph Gear List

Here are the stuff what i used to take photos:
Nikon D80,
Nikkor 50mm/f1.4D,
Nikkor 85mm/f1.4D,
Nikkor 105mmVR/f2.8G,
Nikkor 17-55mm/f2.8G,
Nikkor 18-200mmVR/f3.5~5.6G,
SB-800 Flashlight.

I always wanna have a wide-angel lens, recently i found some discussion in some forums about Tokina 11-16/f2.8, it seems to be a very useful lens to shot photos of landscape, so, at right time, maybe i should take one.
