What someone told you was good information. A fisheye lens is often far better than a wide angle rectilinear lens for uw.

Wide angle rectilinear lenses behind dome ports often have issues in appearing sharp. Fisheye lenses typically don't have these issues.

Either the Nikon 16mm or the Sigma 15 lens would be good for underwater use. Many prefer the Sigma because it focuses more closely than the Nikon.

You should also consider buying the Tokina 10-17, a very highly regarded lens for uw use.

thanks a lot!

But it is a wide angle lens not a fisheye. how that work?

sorry! you are right.. it is fisheye

The Nikon 16mm fisheye and the Sigma 15mm fisheye are both for full frame sensors (for example, Nikon D3 or D700), while the Tokina 10-17 is for DX sensors (almost every other Nikon). They're not exactly comparable.

I use the 10-17 Tokina FE and the Nikon 12-24. They both are good. I wouldn't say the FE is better.

With the FE you have to either get really close to your subject or have a big subject. The FE is great when the viz. is not. The long end of the 10-17 ends about where the wide end of the 12-24 starts. Less distortion with the 12-24 as it is a rectilinear lens.
