This is a review of the Canon 17-40mm lens. This lens isn't for everyone, but if you need wide angle lens that provides a little bit of zoom this lens can handle the job.
If you haven't already got the Canon, you might want to consider a Sigma 17-70mm f2.8 Macro. Much cheaper and gets great results. I would love to own Canon L lenses but in this case I think Sigma is a much better buy. Thanks for the video!
