I shall ignore every lens with a filter thread of less than M 100  :ph34r: or going lightweight with not more than 1.5 kg. Flimsy things, blowing away by wind... 50 MP already are medium format, aren't they? So I'm expecting fat ass glass (what sense would make fat glass ass? See?). Good they leaned towards Sigma design. At least, Canon shows some kind of good taste.
