Dear Dive buddy,
Regardless which model of Hugyfot you hold in you hand, you can be sure that it
is not only the best housing on the market but also the best looking one. Hugyfot
builds underwater housings for cameras as well as lighting systems since 1953.
The story began at a time when the first regulators were build and all the diving
equipment still had to be designed.
During the last decade, Hugyfot has invested a lot in new technologies. Together
with the emphasising of the ergonomical design, this investment has changed the
market of underwater housings. Recognition and a very high quality standard have
made the Hugyfot brand known throughout the world.
Underwater photography is our life.
Happy Diving!

1. Preface
A camera in an underwater housing offers a lot of advantages to the profes-
sional and amateur underwater photographer:
impeccable exposure due to the use of the most modern exposure
techniques of the camera;
direct view on the subject, very short reaction time and swift image
processing;
exact and swift focusing due to the autofocus objective;
parallax faults no longer exist because one looks through the objective
(all settings are displayed on the LCD-screen);as the camera can also
be used on land, a second camera is not needed.
As housings and flashes have a long lifetime and are quite expensive, some
time should be invested in looking around to find the right equipment. Do-
ing this in cooperation with a professional salesman is probably the best
solution.
Different criteria determine the final choice of the camera:
recording technique (viewfinder, controls, …);
functionality and comfort (design of the housing, control switches and
their ergonomical position, …);
price.
Also: some elements that determine ones choice when buying a safari
camera are not important at all when purchasing a camera for “underwater”
use. Cameras are always designed for “on land” use. Therefore HUGYFOT
always designs its housings from the divers’ ergonomical point of view and
translates this through the controls.

3. Hugyfot for NikonD90
It is a trend in underwater photography to use a digital camera that can be
used by the amateur as well as by the professional.
Nothing is as simple as taking pictures with the automatic settings of the
Nikon D90. One can choose to take control himself and set each para meter
to his own preference. The sensitive exposure lever is integrated in the front
shell which is a part of the patented Hugyfot-grip. This enables one-hand
photography. With this sensitive lever the exposure lever of the camera can
be slightly squeezed so the camera is activated. All the settings then become
visible on the LCD-screen. One-hand photography, taking pictures during a
drift dive or point-shooting with the flash in the other hand are “child’s play”
thanks to the HUGYFOT design. Just as easy is the manipulation of the
zoom on the left side, the diaphragm and the shutter speed.
All parameters can be changed through the menu driven system, this can
be operated through the buttons on the back of the housing. The big LCD-
screen of the camera is entirely visible through the integrated window on
the back of the housing. Any flash can be connected through the standard
Nikonos contact.

4. Opening and closing the housing
The HUGYFOT Nikon D90 housing is opened and closed by means of 2 built-in
countersunk bolts.
This guarantees the safest way of clo-
sing. Only with the right key you can
open and close the housing. A curi-
ous buddy cannot open the housing
by accident. Herewith we exclude the
unwanted opening of the housing. To
seal the housing, the socket screw key
is inserted into the countersunk bolt
and then turned until the shells are
squeezed to one another. Stop turning the key when resistance increases
significantly. Further turning the screws hasn’t got any sense and can only
damage the thread. At a depth of 6 meters the hydrostatic pressure takes
over and keeps all the o-rings under pressure. Always check the tension on
the bolts before diving if the housing wasn’t opened in between two dives.
First maintenance command:
The screws, and more specific the tread, must be kept very clean at all times.
The main o-ring merely lies in the o-ring groove. It can be removed by blow-
ing it out with compressed air, by using a credit card or by rubbing two pieces
of paper towards each other against the o-ring so the o-ring pops out of his
groove. Never use a metal object or any other hard material: by doing this you
can DAMAGE the O-ring and the groove.
Second maintenance command:
Whenever the o-ring is dirty or misted up, it must be removed from its
groove (see first command) and cleaned up with soap (do not use corrosive
or chemical degreasers). Afterwards clean it with clear water.
O-rings have to be dried up with a clean cloth (do not squeeze) or by air.
Grease the O-rings (except the main red o-ring) by using HUGYFOT grease.
Pull the o-ring gently through your fingers without stretching it! O-ring
grooves, housing and shell edges have to be cleaned with a clean cloth.

5. Port with bayonet catch
The front port bayonet catch is a secure and fast method to connect the dif-
ferent ports to the HUGYFOT Nikon D90 housing.
The port has a mark which has to be positioned opposite to the mark at the
left of the housing when mounting and demounting the port. To actually
close the port it has to be turned clockwise until the mark on the port is op-
posite to the mark on top of the housing. To demount the port it has to be
turned counter clockwise until the mark on the port is opposite to the mark
on the left of the housing.
When mounting the port, mind that it is held exactly in the middle of the
port mounting. Only then you can press the port so it slides nicely into the
port mounting. Check whether the port is closed properly before turning it
towards the marking on top of the housing. (secure position).
Third maintenance command:
The o-ring around the port can be removed from its groove by pressing it
with 2 fingers.
Port mounting, o-ring groove and bayonet catch have to be cleaned with a
wet cloth. Afterwards let everything dry.
Clean the inside of the portglas with water and soap. Never scrub it with a
cloth. Rinse it with fresh water and let it dry, or dry it with compressed air.
Grease the O-rings with HUGYFOT grease by gently pulling it through your
fingers without stretching it! Put it back into their grooves.

When mounting the port,
A and C must be opposite

port mounting. Then turn
the port clockwise until B
and C are opposite to each
other.

6. Flash connections
Hugyfot housings can be equiped with Nikonos 5-pins or S-6 flash connec-
tions. These flash connections are plugged into a circuit board inside the
housing. An optional TTL-converter is also available.
The flash connection can be shut off by
using a small protection cap which can be
removed by turning it counter clockwise.
The cap has 2 o-rings which have to be
cleaned together with the thread. After-
wards, slightly grease o-ring and thread.
The flash plug also has to be serviced.
Slightly grease the o-rings and thread and
keep the flash contacts dry.
The multiple socket in the housing has
a small ridge. The projecting part of the
connection has a groove with the same
measurements as the ridge of the connec-
tion. Be sure that, whenever plugging the
connection into the socket, the groove and
the ridge fit well together. Only then the
connection is well positioned. Press the
plug gently into the contact. Then turn it
clockwise to tighten it. Whenever the flash
connection has to be removed from a wet
housing it always has to be positioned downwards. If not, the remaining
water can work its way into the flash connection. In that case, the water has
to be removed immediately by using an absorbing paper. Do not close the
flash connection when it is not entirely dry.
Fourth maintenance command:
Keep the inside of the plug dry and clean. The o-rings, the plug and the
thread need to be clean and slightly greased. DO NOT use the housing with
an open multiple socket: this can cause leakage and corrosion!
Be sure that, whenever plugging the
connection into the socket, the groove
and the ridge fit together well.

7. Mounting the camera
Prepare yourself at ease and try to avoid stress!
Obligations when using underwater housings for cameras:
Mount zoom (or focus) control gear (if applicable). Slide the zoom gear
over the objective. Position the gear so that the gearwheel of the zoom
control gear matches the gearwheel of the zoom control inside the
housing.
Remove the protection cap from the objective (if a port is mounted).
Turn the ON/OFF switch onto position OFF (camera and housing).
Turn the tripod screw completely towards the back. Gently slide the
camera onto the camera support until it reclines. The objective should
be centered in the port mounting. If the zoom control gear does not func-
tion properly slightly turn it until the teeth fit. Never use force while
mounting the camera. Be sure the flash connection is free and not
jammed.
Next, fix the tripod screw handfirm. Check whether the camera is
mounted in a stable way without tension.
Slide the flash adapter onto the flash connection of the camera (red
connector facing back of camera).
Turn on the camera.
Check whether all control switches can be operated and function over
the complete range. If not, this has to be checked and fixed before
continuing.
Set the parameters of the camera as much as possible according to the
settings which will be used under water.
If applicable, connect the external flash and test the camera and flash.
If function fails, check the connections for their position and clean
them.
Closing of the housing:
Check the main o-ring and the opposite sealing surface for dirt. If
necessary, clean with a wet cloth. After appr. 5 dives, remove the main
o-ring with a clean cloth by pressing it out of his groove. Clean the
o-ring, the groove and the sealing surface.
