I recently purchased this lens along with the 24-105mm as a part of the fall cash in with cannon rebate program. So, originally, my main reason to get this lens was because it would save me another $50 off of the other lens via doubling the rebates and make it pretty cheap. But now that I have used it for awhile, I am really happy that I got it. The 1.8 maximum aperture does two things really well, lets you take low-light handheld shots and isolates the subject. See my example photos for examples of both of these features. I use this on the Canon Rebel XT and Rebel XTi which have a 1.6X crop factor and make this lens more like a 135mm which is good and bad depending on your usage. This lens produces very sharp results and doesn't weigh much, so it is easy to carry around. If you already have a good range of zoom lenses and are looking for something that will just take really nice, sharp, handheld shots, consider this lens.
