the main purpose was to look at how the sigma 35/1,4  behaved in comparison with the twice more expensive canon 35mm

and how did the sigma behave, mikael?

very nice, much sharper  over the whole area than Canon at 1,4  , less CA , and much sharper in the corners as you can se here

all i can say is wow, how do they do that! sigma wins hands down. great stuff mikael!

well look at Imaging Resource test , lens tip test, and DXO test, all of them are impressed with sigma 35mm

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…

some lenses have that mythical look and feel about them, does sigma qualify in that department too?

it feels very solid build, try one if you have the chance
