The Nikonos III capitalized on the Japanese method of kaizen which means "to change for the better." While other camera makers opted to release new colors and styles for their cameras, Nikon chose to improve on their line of photography gear.
The Nikonos III is famous for its fully-mechanical design that translated to its reputation of being reliable without having the need for batteries. It's a utilitarian camera that you can take on aquatic adventures without worry. It was an interesting design path that Nikon chose for this particular model as they swam against the current of electronic cameras that were filling up the market during the time.
The robust Nikonos III was able to take bumps and dings while being used underwater thanks to its robust construction. Design improvements like the addition of a bright-line viewfinder, sprocket on the film spool for better winding, and the relocation of the film counter window to the top part of the camera made shooting with the Nikonos III a more pleasurable experience compared to its predecessor, the Nikonos II. All these changes and some minor ones like the better flash sync connector and hinged pressure plate quite make up for the original 45,000-yen price tag.
Other Nikonos III tidbits:
- It has a frame that can accommodate 80 mm lenses.
- It was bigger compared to the earlier Nikonos models due to its sprocket and bright-line window viewfinder.
- The Nikonos models were derived from the French Calypso camera design by Jean de Wouters which was dubbed as the original underwater 35 mm camera.
- The Nikkor 35.mm f/2.5 lens, when submerged, yields a field of view equivalent to a ~47 mm lens on land.
