CAMERA DESIGN
O-Ring Gasket
All joints of the Nikonos are sealed by means of O-ring gaskets. These
synthetic rubber rings insure absolute watertiahtness and can withstand
water pressure at depths down to 160 feet (50m)Ñ as deep as you can dive
with Scuba equipment. As pressure increases, the seal becomes even
tighter.
Occasional lubrication improves the life of the gaskets and makes
attaching and removing the lens easier. Make it a practice to lubricate
the camera before each underwater picture-taking expedition using the
lubricant supplied with the camera for this purpose.
The gaskets should be protected froÕ cuts or scratches caused by sharp
objects or grains of sand. Whenever they appear the least bit worn, they
should be replaced. Spare gaskets for the base of the lens and around the
top edge of the interior body are furnished with the Nikonos.
Note: Replacement of all gaskets except the
ones on the lens and around the top edge
of the interior body should be left to an
authorized serviceman Send the camera
to an authorized dealer or distributor, or
directly to the manufacturer.
The Nikonos II consists of three components which fit together snugly to make this a selfcontained,
watertight camera without any need for a separate bulky underwater housing.
Outer housing: Die-cast from thick aluminum alloy and finished in a knurled surface thatÕs easy to
grip, even with wet hands or gloves.
Interior body: Contains the shutter, film advance lever and other moving parts. Removable for film
loading.
Lens: When mounted in place, the lens locks the entire camera assembly together, safe from
accidentally jarring loose.
Note: The Nikonos is watertight only when completely assembled. The components are susceptible
to damage individually. If the interior body or lens is accidentally dropped into salt water or muddy
water, rinse it immediately in fresh water and take it to an authorized serviceman as soon as possible.
