reviewswhat are people saying

"The build quality seems top notch, no play in the focus or zoom rings at all, and very smooth action of both."

"Great lens for taking pictures of the kids, fast, smooth zoom and I don't have to be in their face to get a shot, very sharp pictures..."

"Heavy and bulky; can't imagine travelling with this. Autofocus tends to hunt around a bit."
