Rating : - Decent Zoom Lens
This lens is fairly good for it's low price tag. It has quite a bit of zoom range, which is the main reason I bought it. It is rather slow, but can generally get the job done. I used this lens to shoot a high school soccer game and football game for the school newspaper and yearbook. I got some great soccer results, and got some decent football shots from the students section at night. If you are looking for a low priced zoom lens, try this one out.
