Hello, This look is very sharp and has a great bokeh. In fact, everything you could wish for. But, unfortunately, it is again so far ..... The guys from Sigma probably not cope with the Canon AF protocol. The AF is useless. Not because it is not true, no, they are easy to erziehlen no reproducible results. Time sharp, sometimes not sharp. And hosted by the Studio tripod and laser measuring devices cameras. In three cases the same negative result. After the third lens I've given up. Too bad the optics otherwise awesome.
