#338258 Canon 16-35mm f2.8L II Dome?

You are going to need the proper extension ring with any of theses setups. I use a 70mm with the Zen 9" and nauticam housing. I,m not familiar with the pro-one domes so I can't comment on that one.

Unfortunately all rectilinear lenses lack some corner sharpness behind a dome. The best solution is to use the largest dome you can and stop down on the lens. I use the 16-35 II with the Zen 9" without a diopter on 5D Mark III and find the corners quite acceptable. On a cropped body the corners will be even better. By adding a diopter you may add some sharpness to the corners but I don't think the 16-35 II needs it.
