NIKONOS II
INSTRUCTION MANUAL
2
The Nikonos II amphibious camera is buillt to go
with you wherever your imagination leads you.
Underwater, it performs at depths down to 160
feet (50m) without a bulky accessory housing. On
land, it takes rain, snow, dust, dirt and salt water
in stride. If you can take it, so can the Nilonos.
Despite its rugged construction, the Nikonos II is
as sleek and compact as other 35mm cameras.
Precision engineering and superior Nikkor optics
deliver perfect images in places where other
cameras wouldnÕt dare to venture. And when
youÕve finished your shooting session, just rinse
the Nikonos in tap water and itÕs ready for the
next assignment. To get the best results from
your camera, read these instructions carefully
and pratice using the controls before you load
any film in the camera. Keep this booklet handy
for ready reference until you have mastered its
basics. The few minutes you spend familiarizing
yourself with the camera will increase your
picture-taking pleasure as you explore a whole
new world of photography.
Agood rinse after one
assignment and itÕs
ready for the next.

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.

Lens
The Nikonos 1I comes fitted with a
W-Nikkor 35mm f/2.5 lens as standard
equipment The lens is sealed behind a
watertight glass plate that also covers the
aperture and distance scales. Large,
easy-togrip knobs on either side of the
lens mount control focus and diaphragm
settings. The front lens mount is threaded
to accept lens hoods, close-up lens
attachment and 52mm screw-in filters.
A UW-Nikkor 15mm f/2.8 28mm f/3.5 (both
for underwater use only) and Nikkor
80mm f/4 are also available (see p. 29,
30). Lenses for the Nikonos 11 are
designed so that their lens mounts move
independently of the inner mechanisms.
This helps to absorb the effect of water
pressure when the lenses are used
underwater.
Distance Scale
Graduated in feet and meters.
Depth-of-Feild Indicator

LOADING THE CAMERA
Opening the Camera
The lens in its bayonet mount locks the entire camera together, so it must be
removed first in order to open the camera. Grasp the lens mount and pull the
lens forward slightly until the positioning pins on the lens mount slide out of
the grooves on the bayonet mount. Then rotate the lens in either direction until
the focusing knob or aperture knob points straight up. Pull once more and the
lens will slip free of the bayonet mount. Now you can open the camera by
prying up the interior body with the strap-attachment levers on both sides of
the outer housing. The interior body will come loose and can be lifted out.

Caution: After using the camera in salt
water, or if it is dirty, rinse it thoroughly in
fresh running water to remove any dirt or
salt water residue and dry with a soft
cloth before opening. Never dry the
camera near heat.

LOADING THE CAMERA
Loading
Lift up the film pressure plate. Position a film cartridge
between the film cartridRe catch and the shank of the rewind
knob. Turn the film take-up spool to the right so the slot faces
out. Slip the end of the film leader under the hinged pressure
plate and insert it into the slot. Advance the film one frame,
making sure that the tooth in the slot catches one of the
perforations along the edge of the film.
