Nikonos RS AF

The Nikonos RS AF, introduced in 1992, marked a significant technological leap for Nikon's underwater camera system. It was the world's first autofocus SLR designed specifically for underwater use, building upon the legacy of the legendary Nikonos line of amphibious cameras. Utilizing the standard Nikon F-mount, it offered compatibility with a range of Nikkor underwater lenses, including the unique 15mm f/2.8 RS, which became the widest rectilinear lens available for underwater use at the time. The camera featured a robust, pressure-resistant housing rated to 100 meters (300 feet), maintaining the Nikonos tradition of exceptional reliability in demanding underwater environments. The autofocus system, coupled with the ability to use TTL flash exposure control, greatly enhanced the ease and success rate of underwater photography for professionals and serious enthusiasts, moving beyond the manual focus of earlier models. However, its complex mechanics and specialized nature meant it was a niche, high-end tool rather than a mainstream camera. Production was relatively short-lived, ending in 1995, making it a transitional model between the manual focus Nikonos V and the eventual discontinuation of the Nikonos line.
