Wow I clicked on the link and compared the 2 1.4 and omg the sigma

on that comparison the sigma certainly seems better wide open
but from f/2 the canon is better
i would certainly go for the canon
is this for your horse photography? if so would it not be better to save a bit and go for a better suited lens? obv i do not know what lens/focal range would best suit it tho
