Great Lens with Updated Optical Glass Coatings, Improved Image Stabilization, and 24mm Image Quality!

Summary: I have to disagree with reviewers that say this is only a novelty lens. It is NOT. I'm a professional shooter and I can tell you that the main strength of this lens for MY use is it's optical quality at 24mm. I have used this lens on several Canon 5DIIs and the Canon 6D which present excellent images. I have also owned the Canon 24-105L which only presents acceptable 24mm images out of the box and just above average when calibrated to the users camera.
A lot of hater reviews, but really an excellent lens for the price.

Summary: An amazing lens despite the haters. It's true it's not the sharpest L lens, but it's still an L lens and a lot sharper and stronger than a lot of non-L lenses in the standard zoom "walk around lens" category. The sharpness is not the only factor. The 24-105 f/4L is only slightly sharper than the middle of the range(around 50mm) of this lens in certain situations and settings.
Summary: Pros: Impressively small & lightweight. Goes very well with lighter bodies like 6D. Sharp wide open. IS works (don't expect it to get you tack sharp photos when shooting 2-3 stops below 1/focal length rule; you'll get useable pictures, but not tack sharp). Cons: Little bokeh. I much prefer 24-70 f/2.8 MkI when it comes to separating subjects from the background.
Summary: This is really a great lens. The overall sharpness and build quality that can be expected from an L lens. The macro feature is especially helpful because you dont have to carry a separate lens for macro shooting.
