It's a great lens, comes in different versions. Combined push-pull focus and zoom, 2 ring focus and separate zoom, screw drive, af-s, several incarnations over the years, very solid, excellent image quality... Might be a bit of a bind on a 'manual focus' body and being lightweight. I always enjoyed it on my gripped FX D700 and DX D300. I think you'll find the AF speed depends on the body. My D300 focused it faster than my D7000, and I think that was because the D300 had a stronger screw drive motor.
