I would be happier with a good working 60mm macro lens. Underwater it's a very much a niche lens.

The 180mm F/4.5 which goes to 1.5:1 will be the first AF macro lens for full frame from Laowa. Laowa has already said their with be other macros lenses coming including something in the 55 to 65mm range.

The 12mm F/2.8 (122 degree AOV rectilinear) will also be worth a look if it has a minimum focus distance as good as the 10mm's 12cm.
