As Nikon has returned to competitiveness (and more) in the DSLR market in the past several years, there seems to be a significant hole in their lens lineup. There is no good option for a FX telephoto below the 200-400 f4 and 300 f2.8 in size, weight and cost (maximum aperture would, by definition, suffer). The 80-400 is an ancient lens and known to be both slow-focusing and soft at the long (and most important) end. The 70-200 f2.8 is reputed to be so soft in the corners that it should almost be labeled as a DX lens (where it is spectacular). The 300 f4 lacks VR. The Sigma 100-300 f4 looks appealing, but it isn't stabilized. Which of these lenses would other folks like to see Nikon revise (or, in the case of a 100-300 f4, introduce)?
