Nikonos
The 1961 Calypso underwater camera was created and manufactured in France, inspired by diving pioneer Jacques-Yves Cousteau, and named for his research ship.
Soon its design was licensed to Nikon who re-introduced the camera in 1963 as the Calypso/Nikkor in Europe and Nikonos elsewhere. With the introduction of the Nikonos II in 1968, the original Japanese model became known as the Nikonos I.
