I ordered this lens so that I could take zoom photos at airshows and also try to catch those wily hummingbirds on the fly.It is a decent lens. It doens't focus very quickly - and at times has trouble finding what you want - as many of these new, less expensive lenses do. It's also far louder than the nikon lenses.I am happy with it - and would recommend it for amateurs and more - not a pro-level lens though.
