The Sigma f/2.8 15mm fisheye (Sigma 15mm f/2.8 EX DG Diagonal Fisheye) is considered by many as the go-to fisheye lens for full-frame Nikon underwater shooters. Its minimum focus distance of fewer than 6” and its 180º diagonal field of view makes it a great lens for shooting underwater. The Sigma 15mm performs very well behind 8 or 9 inch dome ports, as well as smaller domes like the Nauticam 140mm. It should be noted that this lens will work behind the popular 100mm Zen mini dome, but part of the lens shade will have to be removed. Whether you are shooting seascapes, split shots, or close-focus wide-angle, the Sigma 15mm fisheye is something you should have in your kit if you shoot a full-frame Nikon DSLR.
