Dear Dive buddy,
Regardless which model of Hugyfot you hold in your 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 professional 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
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. Doing this in cooperation with a professional salesman is probably the best
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, …);
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.
First dive is a checkdive without the camera in the housing.
Check all buttons under water.

3. Hugyfot for Nikon D300
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 D300. One can choose to take control himself and set each parameter
to his 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 LCDscreen 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.
The sensitive exposure lever is integrated in the
front shell which is a part of the patented
HUGYFOT-grip. This enables
one-hand photography.

4. Opening and closing the housing
The HUGYFOT Nikon D300 housing is opened and closed by means of 2 builtin countersunk bolts.
This guarantees the safest way of closing. Only with the right key you can
open and close the housing. A curious 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 blowing 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 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 different ports to the HUGYFOT Nikon D300 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 opposite 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
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).
When mounting the port,
A and C must be opposite
to each other. Make sure
that the port is held exactly in the middle of the
port mounting. Then turn
the port clockwise until B
and C are opposite to each
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.

6. Flash connections
Hugyfot housings can be equiped with Nikonos 5-pins or S-6 flash connections. 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. Afterwards, 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 meaBe sure that, whenever plugging the

nection 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!

Synchronize metering mode selector on camera and housing.
Insert the tripod screw in the base of the camera body. 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 function properly slightly turn it until the teeth fit. Never use force while
mounting the camera. Be sure the flash connection is free and not
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
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
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. Then close the housing.
Turn the countersunk bolds in without using any pressure so that the
two shells are nicely put together. This point is reached when the
tightening suddenly generates resistance.
Check all operational switches in the back shell of the camera. It is
possible that some pressure has to be used to operate the buttons.
Due to the water pressure all buttons are squeezed, so this is the normal situation of operation.
Mount accessories such as flash arm, handle, protection cap, etc…
We strongly recommend doing this first mounting on a table. When one is
forced to work on a floor (ship deck, tent, cabin, …) a clean towel should be
used as a clean surface to avoid all kinds of dirt. Especially the first time,
you should give yourself all the time needed to practise all these steps. Afterwards you will notice that it only takes a couple of minutes to mount your
Opening the housing:
Before the housing should be opened, see to it that the housing is
properly rinsed with fresh water. Make sure that the housing is dry so
there is no more water left that can work its way inside when it is
Put the housing down with the port facing down.
Loosen the bolds.
Remove the back shell gently from the front shell. When resistance
occurs while opening see to it that the cause of this resistance is put
right before continuing. If not, damage to the housing or the camera
may occur.

8. Operation of the leakage indicator
The leakage indicator is nicely fit into the circuit board mounted at the left
of the housing. The moisture sensor is installed at the bottom of the housing. The unit runs on a single 1/2AA size 3.6V lithium battery which lasts
for about 5 years when the electronics are in ‘stand by’ mode. As soon as
a strobe is activated the electronics will notice and they will be in ‘active’
mode. In this mode the batteries will last for about 100 hours. There is no
need to disconnect the strobes to save power, only switching off the strobes
will set the electronics to ‘stand by’ mode. In ‘stand by’ mode, the leakage detector will still be functional. Due to this extended lifespan, no on/off
switch is used. We do recommend to remove the battery when not using the
housing for a extended period.
With the battery installed, the leakage indicater will show a red LED (blinking) when in
standby mode. When the housing is closed
one can observe the red LED through the
back window.
In case a flooding should occur, the red
LED will burn permanently and an acoustic signal will be heard.
The battery, the horn and the signallingLED can be tested when a moist finger is
held onto the moisture sensor in the bottom of the housing. As this will simulate a
leak, the horn will sound and the LED will

9. Maintenance and service
The Hugyfot o-rings are of a very high quality. Their lifetime may be estimated
at 5 years. Nevertheless it is advised to have a spare of the main and the port
When the housing isn’t used for a longer period, it should be thoroughly
cleaned and stored away with closed shells in a dry and dark storage (NO
PRESSURE on the main o-ring). The camera should not be stored inside the
housing and the port should not be mounted.While transporting (airplane,
Transport Company, post …) never leave the camera inside the housing.
Due to vibrations the camera as well as the shells can be damaged. Either
pack the shells separately or bolted together.
Never put the housing in the sun.
Aside from the mentioned maintenance commands, the HUGYFOT Nikon
D300 housing is fairly simple to maintain. Some issues however should be
kept in mind:
When finishing a dive one has to rinse the closed housing with a closed
flash connection (plug or protection cap) under the shower or in a rinsing tub. Never leave the housing to dry up after use in salt water. If it is
not possible to rinse it in fresh water, keep it wet with salt water.
Before opening the housing it has to be completely dry.
See to it that when opening the housing no water can work it’s way
inside. Be carefull with wet hair, diving gloves or wetsuits.
When finishing your diving holiday, soak your housing for 12 hours or
longer. Then wash it and clean it. Certainly at all buttons and in all
corners. (Bolds, buttons, bullets, …).
Clean the bolds with a wet cloth. Remove all salt with maintenance
Remove the battery from the leakage indicator.

A service of all passages is necessary once a year. If you can do this yourself,
the following procedure is to be followed:
Unscrew and unmount all the control switches in the housing with the
small socket screw key (gears, exposure lever shaft, wedge caps, selector switch shaft, …).
Remove the o-ring out of its groove. Use the control shaft or a non
metalic tool.
Wash axe and o-ring with soap (do not use degreasers), rinse with
fresh water and dry thoroughly or let it dry for a while.
Slightly grease with Hugyfot-grease.
Position the greased o-ring in its groove, gently slide the axe back in
and mount the control switch back to its proper position.
When the control switches are mounted you may mount the camera
into the housing. Now check all the controls on their proper functioning.
Always perform a pressure test after removing/installing control switches or
perform a testdive without camera inside the housing.

10. Photo practice
With a Nikon D300 camera in a HUGYFOT housing one can take pictures almost completely automated. To use the camera with all its possibilities one
has to beware of some basic principles. These basic principles are explained
in the following chapter.
The “Auto Focus system” (AF) lets the camera focus in most cases, supposing that the subject is positioned in the centre of the viewer. If not one
has to focus on the subject and keep the shutter release button squeezed.
This way the focus is locked. One can now adjust the composition and
shoot. When taking macro images the depth of field is more narrow and
therefore the AF-system can be defective by particles in suspension. In that
case, focus on the subject and lock this position according to the technique
mentioned above. Next, approach or move away from the subject until it is
focussed and press the exposure lever. Due to diffusion and absorption of
light under water, photography under water is limited to a distance of about
1,5 meters. Nevertheless, shots from a distance of over 1,5 meters are possible but the quality of color, sharpness and glow will be considerably less.
Therefore the golden rule in underwater photography states: “The closer
the subject is photographed, the more attractive the colours and the more
sharpen the shots willl be.”
When adjusting the “diaphragm”, one has to consider a decreasing depth
of field when increasing values of the diaphragm are selected. This depth of
field decreases when close up shots are made.
With a longer “shutter speed”, more light can be catched and the brightness of the shots can be increased. The shutter speed is always to be considered in combination with the diaphragm. The built-in light sensor informs
the photographer about the effects of the combination he wishes to apply.
Always consider that shutter speeds slower than 1/60 second could result
in motion blur.
Hugyfot Housing for Nikon D300
User manual
When taking shots at depths deeper than 3 meters, the use of a “flash” is
necessary to regain the natural colours. The Nikon D300 can be combined
with a flash in 3 modes:
Manual flashes: using this mode, the power of the flash can be adjusted.
The camera will direct and synchronise the flash by means of the X-contact.
The result obtained can be observed on the LCD-screen. In case of an overor underexposure, the power of the flash or the distance to the subject has
to be adjusted and a new shot has to be made.
Autonomous flashes: some flashes have a light sensor which registers the
light reflected on the subject. When this sensor registers enough light, it
will automatically shut down the flash. Only by means of the diaphragm,
the flash light can be limited. To obtain a correct simulation, the diaphragm
used on the camera has to be adjusted on the flash. In case of an under- or
overexposure, a higher or lower value of the diaphragm has to be adjusted
on the flash.
TTL flashes: using this mode, camera and flash communicate and set the
right values of diaphragm and shutter speed to obtain the correct amount of
light needed for the shot. This mode can only be obtained by using a Nikon
D300 compatible flash or by installing the optional TTL converter.

According to the objective used on the camera, different ports are available.
- Flat ports for macro lenses
- Wide angle ports for wide angle lenses
- Fish eye ports for fisheye lenses
All these ports can be adjusted in length by means of extension rings. One
wide angle port can therefore serve for different wide angle lenses by only
using extension rings. See for our port charts.
Neoprene protection caps are available for all our ports.
