Especially I want to say about autofocus. Do not believe if they write that it is slow and lying. In terms of speed, it is not inferior to the Canon ones, Well, maybe almost as good. At least I did not notice that it is slower. And it focuses confidently in any light. There are of course glitches if the surface is homogeneous and monochrome, he has nothing to catch on. For a long time I chose between 18 -35 and the Sigma fix 35 1.4, it is clear that the fix is better, but I really wanted to have a wider angle as well. I decided to take 18-35 and am glad that I did just that. I advise everyone. After some time, when I work with him, I will add a more detailed review.
