Sigma 70-200 OS version.

Has anyone used the OS version on a Canon mount, and if so what is your opinion of it, especially the AF speed?

Now that the price is 50% of the Canon MkII it seems to be worth a realistic look.

theres a review on digital rev, the af speed is suppose to be as good as the canon, image quality is suppose to be no way near.

And there are other reviews stating the opposite, or in the case of AP saying that it is almost as good all round - hence asking for real world experience.

ok fare point, always best to go try one your self, then atleast you know if your happy.
atleast they have changed the coating of the lens.
if its anything like my 50-500mm os it will be top.
