very nice, great test!

yep, the color fringing at 1,4 is not nice in the canon, un corrected

from lens tip

The Sigma has the best results of all 1.4/35 lenses, tested by us so far in the categories of resolution, distortion, chromatic aberration and coma correction. It also fares very well in the case of astigmatism correction and the autofocus accuracy, being one of the cheapest lenses in this class of equipment. I think I don’t have to add anything more…
