The Tokina AT-X 124 AF PRO DX II lens is Tokina's first lens with a DC motor added for Nikon AF mount, which allows autofocus with the motorless Nikon D40, D40x and D60 digital SLRs. (The Canon version has always had a built-in AF motor.) Tokina plans on adding motors to all their Nikon mount AF lenses over time. Version II also features an improved multi-coating, for reduced flare and ghosting when shooting in backlit conditions.
I just bought one of these myself and will post photos from it shortly.
