Nikon Nikonos I (Nippon Kogaku) Waterproof Underwater 35mm Camera Body, Black Review

The Nikonos I, originally branded Nippon Kogaku before Nikon adopted the name, is a historically significant waterproof 35mm film camera body introduced in the 1960s. It was one of the first purpose-built amphibious cameras designed for underwater photography, capable of diving to moderate depths without a separate housing. This legacy rangefinder system uses interchangeable Nikonos mount lenses and operates with manual controls, making it a mechanical workhorse suited to both diving and harsh weather conditions.

Today, the Nikonos I is a vintage collectible rather than a practical tool for most creators. Film shooters interested in underwater photography now have more modern amphibious film options or can use digital systems with housings. This used example from KEH is listed in bargain condition at $59, meaning it shows heavy wear and may have functional quirks. It's best suited to collectors, film enthusiasts curious about Nikon's underwater heritage, or those seeking an affordable entry into vintage underwater film shooting with modest expectations.
