16-35mm III faster focusing @ 35mm than 35mm f1.4mk1?

Seeing if i can get rid of my 35mm. My current 16-35 mk1 is noticeably slower and less accurate focusing at 35mm than the standalone 35mm f1.4L. Have there been any tests to confirm if the mk3 focuses fast and accurate? I assume 3 generations now and it should be pretty awesome?

It's a pretty safe assumption that any new Canon L (USM) zoom will be faster and more accurate than any lens released before 2012, at least when coupled with any of the more recent bodies (5D Mark III and newer, XXD line or higher). I believe that Canon changed the logic behind AF to include some closed-loop checks (as referenced by Roger Cicala from Lens Rentals) and the system is better.

I can attest that the 24-70/2.8 II and 100-400 II are without peer in focus performance. I'd bet the new 16-35 III is similar, but I have not seen any testing.

AF speed and accuracy is affected also by the AF-system in the camera, so take results on a different camera than yours with a big grain of salt.

Yea, got a 5d2 here.
