I would go with the Canon mkII, I have one with the 1.4 extender, made for each other and it works great. Sigma in many of their lenses has had a focusing issue, I can't say that about this new lens but I know it won't be an issue with the Canon lens.
Thanks, I appreciate your quick response. The reviews I've seen on both these lenses has me wanting the canon mk2.
