10 out of 10 points and recommendedFast Focus, Wonderful Image qualityNone with the lens. Canon should have included Lens Hood.
I use this lens for all my macro photography, in fact, I use it 50% of the time during the summer month. The images are sharp, as sharp as they can be using Digital SLR, and the quality of picture is incredible.reviewed December 20th, 2006 (purchased for $650)
When working within the 12 inches of the subject, I find that I need to switch focus to manual mode, but my other L series lenses are no faster at focussing when working within the minimum focusing distance.
If you are looking for a macro lens, you can't go wrong with this one.
