It featured a fully watertight body, refined shutter and control mechanisms, and expanded lens compatibility, making it easier to operate underwater. With enhanced ergonomics and reliability, the Nikonos III allowed photographers to capture sharp, vibrant images even in challenging underwater conditions. This model continued to build Nikon’s reputation for producing professional-grade cameras that set the standard for underwater photography.
