Great success for Nikon! This 80-400 G lens is among the very best lenses ever, and will be for long time! Cost every penny you spent on it!
Long story shortly - the best Nikon's long zoom, better or equal to best primes of its range; Absolutely sharp at any zoom positions, even wide open; There isn't any kind of CA or geometrical distortions significantly enough to speak about; Fast and reliable AF.
There is enough of space to make hood telescopic, always ready; Actually, this lens doesn't need so big hood; I am using short 1" third-party metal one, over the B+W filter
