10 out of 10 points and recommendedoptical quality, build quality, quick focus, efficient stabilizer, price -performance ratio.a bit longer focus distance compare to the other models.
I bought this lens after long searching and reading, compare it to the 4 or 5 canon models, and also tamron and sigma other models. as i seen it, there is no better option for the money!reviewed January 27th, 2015 (purchased for $950)
sure you can always seek more from your gear, more speed from the focus, more quality from the optics, and also shorter focus distance and lighter weight...
this is my favorite lens since, and it brings me great results in studio or in outdoor photography, with sharp and accurate colored pictures!
also, at the same quality, It left enough bucks in my wallet to get my Tamron 24-70, instead of wasting all the money just for the 70-200 canon model...
