after searching much, i came to the conclusion that the Sigma 12-24mm is the only ultra wide zoom available for Nikon full frame D700. can that possibly be?
i just got the D700 and one lens: Tamron 28-300mm, and would like to complement it with an ultra wide zoom, rather than duplicating the range (at this juncture) with a constant f/2.8 midrange such as a 28-75mm or so.
a few personal, subjective biases: i prefer zooms, whenever possible, and i prefer VR or VC, whenever possible.
my personal feeling is that, hey, we're in 2009, why wouldn't we want VR/VC whenever possible? It will buy us a couple of extra stops. Yes, i recognize that i'll need it far less with the superb higher ISO performance of my D700, yet, more choices of exposure is additional control for any situation at hand. thanks in advance and looking forward to hearing!
