You can check my reviews of the 16-35 f2.8 L II USM lens here: https://www.indiawilds.com/diary/canon-ef-16-35-f2-8-l-ii-usm-lens-review/

and the review of the 24-70 f2.8 L USM lens: https://www.indiawilds.com/diary/canon-24-70-f2-8-l-usm-lens-review/

Since you are going to use the 1.6 crop factor camera, the 16-35 would be good. The 24-70 f2.8 L USM lens will appear heavier. Both are great lenses for stills as well as video. I use them with C300 as well as with 1D Mark IV for video.
