Many of us wildlife shooters are still waiting on a hand-holdable and reasonably affordable (under $3000) telephoto zoom lens that goes to at least 400mm. I went back through NR and here are the most recent Nikon patents in that range, quoted from NR:
Jan 13, 2011: "Nikon patent application .... is for a new full frame 200-500mm f/4-5.6 lens."
Dec 13, 2010: "Nikon filed a patent application in Japan for a AF-S 100-400mm f/4-5.6G VR ED lens."
Nov. 15, 2010: "Nikon files patent applications for an … 80-400mm f/4.6-5.4 lens."
Canon's 100-400 is expected to be updated in 2012 as f/4-5.6. Will Nikon finally come out with something to compete with that?
BTW very happy so far with my new D800, mostly using with 70-300 vrii.
