You should consider the new sigma 70-200mm 2.8 OS
I would strongly recommend not getting this lens for video. While zooming out, intuitively, your subject is moving closer to you, which means you're pulling focus towards you as well. the zoom and focus ring turn in the opposite direction in this regards, which is fine for photo, but terrible for video. sigma makes awesome lenses, but this lens in particular, isn't all that great if you plan on shooting video while pulling focus and zooming.
and everyone stfu about not zooming and pulling focus while shooting, there are plenty of applications where you do this as a camera operator and can't have follow focuses or rigs attached.

I've had the 70-200L in a bunch of flavors. f/4, f/2.8, f/2.8 IS mark I and mark II. The f/2.8 IS mark II is hands down the best zoom lens I've ever owned, and I've owned plenty. It's as sharp as my L primes, the stabilization works amazingly well and the bokeh is just beautiful. In the midst of considering moving to Sony and their Zeiss glass, having to not shoot with the 70-200L IS mkII is keeping me from making any rash decisions. That zoom has actually got me back into using a zoom as a primary lens instead of my beloved 85L or 135L! Yes, it's THAT good.
the 70-200 2.8 II is an amazing lens in terms of stabilization as well. regardless of what people say about using IS for video, there are tons of applications where this is necessary.
out of all of the 70-200's, my personal favorite to film with is the 4.0 IS, just because of the size of the lens barrel. It's important to pull accurate focus, and for most of what I do, I can't attach a follow focus to my set up. the 4.0's smaller lens barrel is much easier to pull focus with.
