Nikonos II (Calypso II)

The Nikonos II (Calypso II) represents Nikon's pivotal entry into the specialized world of underwater photography, building upon the revolutionary French-designed Calypso camera originally developed by Jean de Wouters and Jacques Cousteau's team, which Nikon acquired and refined. This fully amphibious camera was a significant technological achievement, housed in a robust, pressure-resistant metal body designed to function reliably in harsh aquatic environments down to 50 meters. Unlike conventional cameras requiring bulky housings, the Nikonos II was inherently waterproof from the moment it left the factory, thanks to its unique double O-ring seals and a bayonet lens mount that sealed automatically upon attachment. It utilized 35mm film, supporting a range of Nikonos-specific wide-angle, standard, and macro lenses, including a groundbreaking 80mm lens offering true 1:1 magnification underwater, a critical capability for marine biology and documentation.

The camera's design prioritized simplicity and reliability for divers. It featured a large, bright viewfinder with automatic parallax correction, crucial for composing shots underwater where light behaves differently. Controls were large, deeply knurled, and operable while wearing thick neoprene gloves, including an oversized shutter speed dial (1/30s to 1/1000s) and a frame counter. The fixed-focus 35mm lens (or the optional interchangeable lenses) allowed for zone focusing, a practical approach given the challenges of underwater optics. Its enduring legacy lies in democratizing serious underwater photography for professionals, scientists, and dedicated amateurs alike. It became the undisputed workhorse for underwater exploration and imaging for decades, capturing countless scientific discoveries and breathtaking imagery in oceans, seas, and lakes worldwide, cementing its status as an essential tool in sub-aqueous visual documentation.
