When I read that Sigma is preparing this lens (and I read this news on April 1), I thought it was such a joke! )) The lens turned out to be amazing (despite the small range of focal lengths and the lack of a rope for the cover)))! It is sharp, very sharp starting straight from 1.8! No focusing issues. Always right on target (both 650D and 70D). Sufficiently contrasting, neither yellow nor bluish;) All the lenses that had previously fallen into my hands were a compromise of characteristics (fast, which means it’s not sharp and soft in the open. Well made, nothing dangles and doesn’t crawl back and forth when zooming, which means it’s expensive to madness). There is simply no other picture like this! 16-35II, 17-40 L series on crop are not as good on their "dark" (2.8 and 4.0, respectively) minimum apertures, like this one at 1.8 ! Plugs and ALL fixes in this focal range. I am delighted! I took it for ~ 26000. I think it can be sold for more Despite the focal length and weight, I consider it the BEST LENS for crop.
