Native FE mount there is only one option and that's the Sony Zeiss 16-35 f/4 which is a good lens and the one I use. With an adapter, the best choice is the Canon 16-35mm f/4L - coupled with the Metabones IV adapter and latest firmware - this is also a very good performing combo. That's about it on the zoom front. I would not recommend either the Nikon 16-35 f/4 or the Canon 16-35 f/2.8L II over the two that I mentioned above.
