mrc4nl: "According to Canon, the 11-24mm's front element is the largest ever manufactured for an SLR lens, at 87mm in diameter"
Nah, the front element of the nikon 6mm f2.8 is bigger(by a wide margin) 200mm!
I was wondering about that staement too.Front elements in the 200mm/f2.0, 300mm/f2.8, 400mm/f3.5 and 600mm/f5.6 are about 100mm in diameter, while in the 300mm/f2.0, 400mm/f2.8, 600mm/f4.0 and 800mm/f5.6 are even bigger at about 150mm. All of them way bigger than that in the 11-24mm/f4.0. All of those lenses have been made by Nikon and many of them by Canon.
Miwok: Why should go with this camera when a NEX-6 give me almost the same for half the price?
It's your choice of course.
However, it appears you are a little pessimistic about the performance of the X-E2 and at the same time way too optimistic about the price of the NEX-6.
Good luck with your purchase.
