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

to each other. Make sure

that the port is held ex-

actly in the middle of the

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.
