The Nikonos II, introduced in 1968, was an upgraded version of the original Nikonos I, refining the design for greater reliability and ease of use underwater. It retained the fully watertight body and rugged construction, while improving controls, shutter mechanisms, and lens compatibility. Like its predecessor, it supported a range of high-quality prime lenses, allowing divers and underwater photographers to capture clear, vibrant images with precision. The Nikonos II built on the success of the first model, cementing Nikon’s reputation for durable, professional underwater cameras and further advancing the capabilities of underwater photography.
