Underwater camera housing manufacturer SeaCam recently reported that they are going to reengineer  the classic Nikonos RS 13mm fisheye lens for use on Nikon DSLRs.

The Nikonos RS 13mm fisheye lens was launched in 1992 and discontinued in 1996. However, there are still many of these original lenses on the second hand market.

SeaCam recently communicated to offer a service in order to adapt original Nikonos RS 13mm lenses for use on today's DSLRs. See the article on WetPixel.com.
