Has anyone used this for video and what were your results? Concerned with vignetting...and because it's a non IS lens. And what type of ND filter are you using. 0.6 - 0.9? I usually shoot with the 24mm IS 2.8 but I'm looking for something a bit wider for a golf course shoot. Thanks, Chris.
I use my 17-40L (at 17, of course) on my 5D Mark III when I want to go really wide. Usually for stills, though, so I haven't used an ND on it. It's quite a bit lighter than the 16-35, and 99% as sharp. I also have the 8-15L but I've never flown with that one.
