The 80-400VR has been around for ages and yes, the focus is slow. The lens uses a screw drive type af system that is slower and pre-dates AF-S. This makes catching action more difficult or sometimes maybe even impossible. That being said, the lens is still very sharp.
The big advantage with the 80-400 is that without the collar it weighs in at just over 2.5 pounds. Add VR to that and you have a big lens that is not difficult to hand-hold. Try carrying a tripod through rough terrain or even using a monopod when you’re going after birds (or squirrels) and you’ll soon see the value of being able to hand hold a big lens.
I’m still checking out other big lenses but for me the portability makes this one worth a second look.
