"Mounted on my Nikon D90. The lens capability is as good with its Nikon equivalent at half the price after rebate. Autofocus speed is just fast enough for my application. The picture quality at low level light with flash activated on auto-mode is excellent." bhphotovideo.com
"I have had this lens for only a few weeks, but it's definitely become my primary lens for my D90. I really like the weight and size." bhphotovideo.com
