Description — Nikon IV-A
The Nikon Nikonos IV-A is a 35mm film camera designed specifically for underwater photography, manufactured during the 1970–1979 period. It uses the Nikonos Bayonet lens mount and is compatible with underwater lenses — the camera is not designed for general surface photography use with standard interchangeable lenses. Focus is entirely manual, and the camera is driven by a mechanical shutter, keeping its core operation straightforward and electronics-independent.
At 950g, the body has a reassuringly solid weight. Flash photographers will find connectivity through both a cold shoe and a proprietary flash port, offering some flexibility in lighting setups for underwater work. Film compatibility is limited to the 35mm format.
As a vintage underwater camera with a dedicated bayonet lens ecosystem, the Nikonos IV-A is a distinctive piece of photographic history that still functions as an active shooting tool for film photographers interested in underwater or rugged-environment photography.
