"This inexpensive zoom is solidly built, operates smoothly and has minimal chromatic aberration (purple fringing'). Very useful outdoors and for general telefoto purposes. I expected softness at the end of the zoom range but was pleasantly surprised (!). Allows me to find interesting faces in a crowd and capture fine details of remote objects (e.g. when filming architectural curiosities). Not too heavy and, when attached to a A700, balances well. The lens does not creep and requires just the right amount of force in changing the focal length" bhphotovideo.com
