"I've owned this lens for two weeks and couldn't be happier. I've shot images of dogs running full speed and the focus keeps up with them. I've also shot some humans at 150mm @1/30th sec. and they are as sharp as could be. I am 100% happy with this lens."
"I am using this for outdoor on-location portraits on the D700. This lens is absolutley excellent in terms of optical quality, sharp at f/2.8, very pleasing bokeh, and it focuses fast as lightning."
"At night, it's a great lens. It's 2.8, and a zoom lens. Not to mention, the AF is surprising quick and doesn't lead to missed shots if you have any sort of anticipation."
