Thank you, BC. I myself feel somewhat confused too. My photography subject is quite divergent so sometimes I am not very sure which focal length best fits my need even it is restricted to the WA-UWA range. I know that I need a fast WA prime, preferablly in the 24-35mm range. The reason that I asked about the Zeiss 21mm f2.8 is as follow: 21mm is not very far from 24mm and I sometimes indeed need this focal length with a large aperture (e.g. shooting a tree with a not far background wall and wanting the backgroud to be blur), and if in the mean time the Zeiss 21mm can procude much better landscape image than the Nikon 16-35mm on D700 then perhaps it is good to buy the Zeiss 21mm. However I doubt that on D700 the Zeiss 21mm can produce much better landscape images when stopped down.

Both the Sigma 24mm f1.8 macro and the Samyang 35mm f1.4 then make a bit more sense, as one is on the wide and one on the long end of the range you are thinking of, and both open up considerably more than the Zeiss 21mm f2.8. And both are relative bargains too. The wider Zeiss is mainly a landscape lens, the other two are a bit more versatile (the 35mm as street shooting lens, the 24mm as close up wide angle lens).
