Best wide angle lens for full frame video making?

I have a 5D mkIII and will mostly be shooting video. I'd like something like the 10-22 Canon, but one that would be full frame compatible, and one that I could shoot with stuff similar to this:

I've looked into the 14mm Canon and Samyang but I think I need a wider lens.

Any ideas?

every canonion wide dilemma

sigma 12-24 is an option

There is no best, just better.

24L would be perfect for what you want. Anything wider on full frame starts to distort heavily and look like fisheye (blegh)

one of the new canon IS wide angle primes would be ideal for video IMO.

Samyang 14mm. You'll use manual focus anyway when shooting video. Stopping down the lens you'll have pretty much everything in focus when you shoot, which should be the purpose of a wide angle lens. The 2.8 will help you shoot at night/low light

The 24mm is nice but the 10-22mm gives you range. Set at 15mm it is the 24mm equivalent, at 22mm it is the 35mm equivalent.

My vote would also go to the Samyang 14 mm. Great lens without fisheye distortion. Manual focus isn't a problem with 14 mm and this thing is very very sharp. To me the only downside is the lack of a filter thread.
