There are a couple of wonderful-looking Nikon lenses floating around in rumorland that haven't been announced yet (despite pictures of them AND the optical diagrams having appeared). I was a little disappointed that the only lens we saw with the D3s was an 85mm DX macro (why release a DX lens with an FX camera)? The easy one to build is the 16-35 mm f4 FX - that should be achievable with superb optical quality for a very decent price for a pro lens($999?)... It is quite a bit less radical than the excellent 14-24mm f2.8, which I don't own only due to the bulging front element (which scares me as a nature photographer in the field). I'm also looking forward to the 100-500, although that might be hard to get top optical quality out of (it's supposed to be a successor to the 80-400, NOT a $6000 bazooka like the 200-400). The only zooms I have heard of reaching 500mm or more are either mediocre (mainly various $1000ish and below Sigmas) or incredibly heavy and expensive - Sigma, Nikon and Canon have all released VERY long zooms in the $10,000 and above range with superb optical quality, but so heavy that they are really meant for fixed mounting at a sports stadium or on a vehicle for wildlife work - no tripod short of a Gitzo 5 will hold them! If Nikon really has something that goes to 500 in a handhold/monopod lens (size and weight of a typical 80-400 or at most modestly heavier) with great quality (or at least great quality to 400 with an acceptable "emergency use" 500), I think a lot of people who photograph in the field will thank them for it (even if it IS a bit slow at the long end) - I know I will... That could be a $2000-$2500 lens and still sell a bunch of copies.
