Can I have your opinion please? I am looking at this lens: Tokina 12-24mm f/4 AT-X Pro DX Zoom Digital  Lens for Nikon AF Mount. 
I want a wider angle lens than my 18-55mm for  landscape photos. Fixed income so 'saving' for a better lens is not  really an option. If I can get a used one for around $375, will I be  sorry? Can I use this lens on my D7000? Thanks. 						Laura
