Nikon Nikonos-III
The Nikonos-III, launched in 1975, was an enhanced underwater camera that added through-the-lens metering to the proven Nikonos design for more accurate underwater exposures. This specialized 35mm camera featured waterproof construction rated to 50 meters (160 feet), incorporating center-weighted TTL metering that dramatically improved exposure accuracy in challenging underwater lighting conditions. The Nikonos-III maintained the bright optical viewfinder, manual exposure control, and compatibility with UW-Nikkor underwater lenses while adding modern metering capabilities. Key improvements included reliable TTL metering, enhanced sealing systems, and refined controls for easier underwater operation. The camera was designed for serious underwater photographers, marine biologists, and diving professionals who needed precise exposure control in the variable lighting conditions found underwater. The Nikonos-III became extremely popular among underwater photographers for its combination of mechanical reliability, accurate metering, and professional image quality, solidifying Nikon's dominance in underwater photography equipment.
