Again this goes against the Lenstip.com findings - they said the lens is starting of pretty soft all over wide open and only improving gradually. A "classic" sharpness curve, not the one typical of modern fast lenses (which usually have very sharp center even wide open at the expense of low quality in the sides and corners).
Based on Lenstip findings, I wouldn't bother. Based on Photozone findings, this lens is definitely interesting (though since it's a "dumb" lens, I'll hardly be considering it seriously even though I'll eventually get a fast 24 of some flavour).
Come on Sigma, where is our new fast 24 with HSM! <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/smile.gif' class='bbc_emoticon' alt='
Well, the bokeh shots were taken at very large apertures and the center looks pretty sharp to me ...
