Tested on the same machine I see that sigma have:
more resolution on centre from f1,4 to f2,8
less ca
less vignetting
less distortion
faster autofocus
less resolution on border and extreme but without focus shift when stopping down
for half the price I think that.... it's better the nikon... <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/tongue.gif' class='bbc_emoticon' alt='
' />
I think that for portraiture photos there's no way new nikon it's better than sigma.. or it's not?
