I want to hear from someone who actually
bought the Nikon version and 16-9/ Novoflex (or cheap Chinese versions) Nikon-G to Canon adapter for their 5D. Was the view worth the climb? Would you trade for a Canon version (for an extra grand*
)? I'm assuming the Canon version won't be a big (or any) improvement. By most accounts (that I've read anyway), and seems to be born out by the constant stream of barely used Nikon 14-24's on E-Bay - great lens, but is big, heavy, prone to flare, bothersome front element and just not that useful.

The Nikon is currently $2K new @ B&H - considering current pricing, the Canon is probably going to be at least $3K (or $4k with IS).
I'd rather just have a killer 16L prime that takes filters, but that'd probably be $3K also.
Looks like Sigma has really stepped up their game - how about it? The Zeiss 15mm looks really good, but its also $3K - trend? or I'm still waiting for a FF mirrorless with smaller and hopefully cheaper UWA lenses.
