Super Wide Angle EF 14mm f/2.8L USM Autofocus Lens (http://www.bhphotovideo.com/c/product/12066-USA/Canon_2508A002_Super_Wide_Angle_EF.html)

In terms of performance, price, build.

Minolta/Sony/Sigma/Tamron?
Thanks

Sigma 14mm f/2.8 EX or Sony AF DT 11-18 F4.5-5.6?

Dunno if the performance and build will be up to par or better... I doubt it. But the price should be lower. :)

By the way, there's already a Mark II version of that lens. :)

I think there's a tamron and a sigma version. 14 2.8
