Negative Positive
Title: Great starter telephoto.
Review: I've used this lens since I started shooting about a year ago, and while I'm currently upgrading to something with better glass, stabilization, and more reach (I primarily shoot aircraft), I'm keeping this as my intermediate-range lens for the foreseeable future. With a relatively slow aperture and no stabilization, it's a very demanding lens to use on aircraft, but if you know its limitations and compensate for them, you can get some truly outstanding shots. Its shortcomings have helped make me a much better photographer from a technical standpoint.Four stars because you just aren't going to find a better lens at this price for the EOS series (until Canon makes a better one). Highly recommended for beginners or casual photographers who just want a little more reach, but if you are a serious photographer that shoots with high-dollar gear that does a lot of your work for you, this lens will probably piss you off and you should stay away.
