I use the both internal & external I find on both that depth of field is something you have to use to & it can take a little while to get the
Hang of it. I would say that the external are more user friendly as has been said you can remove them under water, I think I got mine from dryron which push into the front of my SeaCam port. When I use my 12/24 wide angle Nikon I use a Lens diopter with a small
Dome port which sharpens the edges a great deal.
