According to Canon Rumors and The-Digital-Picture, Tokina will be offering a MarkII update to their famed 11-16mm ultra wide angle lens for Nikon and Canon mounts this spring!! Personally, this is some of the most exciting news I've read in a long time. I have always been a big fan of Tokina's original 11-16mm lens, and regardless of some of its shortfalls, it is still my primary lens for landscape and astrophotography. I truly can't wait for the update to come for Canon mounts - even though we have to wait a few months longer than the Nikon boys. A translated spec sheet is provided below (credit Canon Rumors):
