Have you tried AF speed and accuracy against the 35 L?
The AF speed and accuracy are as good as anything Canon offers. Sigma has finally nailed AF with Canon.
I would argue this is a better lens than 35L in every way but weather sealing. Some would favor the OOF rendering of the Canon over the razor sharpness of the Sigma. To each their own. No reason for a current 35L owner to switch though.
