What's that? I just got a 200-400mm f/4 VR and now I have the new 80-400mm AF-S VR? As sharp as the 200-400mm is, I think the 80-400mm fulfills my needs better. For a zoom, portability becomes a lot more important. Nikon threw a little bit of a wrench into my plans by announcing the new 80-400mm so soon after I acquired the 200-400mm f/4, but the nice thing about used glass is that it maintains its value well. I'll be selling the 200-400mm. The nice thing about the new 80-400mm is it's small enough that I can toss it in a backpack, which I did when I went to Florida on business earlier this week. The new lens is pretty awesome. Fast to focus, very effective VR, and sharp @ 400mm wide open. Those were my three complaints with the old 80-400mm, and the reasons I didn't own one.
