"Excellent budget telephoto lens"5.0 starson by plogue87
Pros: Lightweight, fast autofocus.
Cons: Made of plastic, sharpness drops noticeably at 250mm
Summary: I've been using this lens for a short time and have found it to be an nice compliment to the standard lens kit on my Canon Xsi (EOS 450D). I typically do a lot of landscape photography, however when I want to get a shot of some distant features this lens allows me to capture some of the details that the 18-55mm lens can't capture. I would recommend it to anyone on a budget (especially college students like me), and those who are just delving into dSLR photography. This lens can also be dificult to purchase from physical stores (had to order from an online store).
