Re: Upgrading from GoPro, Seeking advice...

You don't really need interchangeable ports for RX100Va. The longer lens of models VI and VII demands them, but the 24-70mm in Va is fine with a fixed port. Keep in mind that a proper wet wide lens - Nautical WWL-1, Kraken KRL-01, Inon UWL-H100, AOI UWL-09, etc - will give you a much wider field of view than your lens is capable of on its own, typically about 130 degrees diagonal, compared to 84 degrees native AoV. When you put the lens behind a flat port underwater, it shrinks further to about 60 degrees due to refraction, and a dome, whether dry (as on the SeaFrogs Salted Line housing) or wet (such as a Meikon wet dome or Backscatter Air Lens) will restore the lenses in-air field of view, but it won't actively widen it - for that, you need additional lens elements.
