Has anyone used this lens? I know Moose Peterson endorses the older, slower version (14mm f/3.5), but I would think this new lens should be better, or at least faster. It's got an HSM Nikon mount, built-in lens hood, and a gelatin filter holder. I'm considering it, along with the yet-to-be-released Tamron 14mm f/2.8 Aspherical (IF) Rectilinear (though the latter lists for $1,400 or so, while B&H has the Sigma for $710). Opinions?
