A Variety of Uses  
The Fantasea FD-70N housing is more than just an underwater camera system. It protects  
the D-70 against damage from such environmental conditions as rain, snow, dust, sand,  
and dirt. It is perfect protection for active outdoor sports, where these elements would  
normally not allow an advanced camera like the D-70 to be used without danger of  
damage. The lightweight, compact housing and handles make it easy to hold and use  
while sailing, fishing, kayaking, backpacking, or just for fun at the beach or around the  
pool. It will also provide a valuable tool for many commercial, industrial, and medical  
applications, because it is impervious to most liquids, and sprays.

Preparation of Housing Before the Dive  
Make Common or Required Camera Settings:  
Prior to inserting camera in housing, it is recommended that Menu option settings be  
made according to the preferences of the user. Most of these choices are ones that will  
remain unchanged for most of the time while diving, and therefore it will be more  
convenient and less time consuming to make the settings prior to diving.  
Mount Housing Port:  
Clean & Lubricate Port O-ring [for Port O-ring only]  
1. In order to properly maintain the Port O-ring you must periodically  
remove port O-ring from channel using only your fingers.  
2. Push and lift the O-ring from its channel.  
3. Do NOT use any sharp instruments, such as knives or dental picks, to  
remove O-ring. You may accidentally cut the O-ring causing a potential  
leakage.  
4. Inspect the O-ring visually and by feel for any cuts, nicks, flat spots,  
stretching, or any debris, such as sand, dirt, lint, hair, or other matter that  
could compromise the integrity of the seal.  
5. Clean O-ring by soaking in fresh water until all debris is removed.  
6. Dry O-ring with a soft clean cloth. Be careful it does not leave any lint on  
the O-ring.  
7. Lubricate the O-ring with the supplied silicone grease. Do not over-grease  
the O-ring. It only requires enough grease to allow it to slip into place and  
make a seal. It should be slippery and shiny but without any abundance or  
build-up of grease. A teardrop amount is usually sufficient for proper  
lubrication.  
8. Inspect the O-ring channel for any debris or foreign matter that could  
damage the O-ring or cause it to lose its seal.  
9. Clean the O-ring channel using a damp cloth or Q-tip. Be careful not to  
leave any lint behind.  
10. Replace the O-ring in the channel by lifting it over the end of the port until  
it sits in its channel. Be sure the O-ring is not twisted or deformed and out  
of position in any way.  
11. Mount the port on the housing body by aligning the threads on the end of  
the port with the mount on the housing and screwing clockwise until it is  
FULLY screwed in place.  
12  
 
The FD-70N lens port uses 2 radial O-rings for a watertight seal. This is  
a different type of seal than used to seal the two main halves of the  
housing itself. That seal is a compression gasket. Radial O-rings are  
affected by friction when closing the seal, as it rubs against a housing  
wall. Compression gaskets are not affected by friction as there is no  
movement or rubbing against any wall. It is a direct face-to-face seal.  
Therefore a radial O-ring, such as the O-ring on the port, requires  
lubrication. The main housing gasket, a compression seal, does not  
require any lubrication. It only requires cleaning.  
Note 1:  
Lubrication of an O-ring does not improve the seal. It only reduces the  
amount of friction on the O-ring when it is being moved into sealing  
position. The amount of lubrication required on the port O-ring is only  
enough to allow it to slip into place without friction, so it does not twist or  
become dislodged. More grease is not better, and could in some cases  
have a negative affect if it is applied in large amounts to form a build-up  
that could trap any debris or foreign matter.  
Note 2  
Open Housing:  
Release all three latches at same time, and lift off back half to open housing.  
Inspect and clean gasket:  
Use a clean wet cloth. Use only water to clean the gasket’s sealing surface.  
Do not remove the gasket unless there is evidence that there is a need to  
clean the underside surface, or the channel it sits in.  
If the gasket does need to be removed for cleaning or replacement, pull up  
on the gasket tab to lift it out of its channel.  
When replacing or changing gasket, begin by aligning the gasket tab with its  
cutout slot in the housing channel. Work the gasket down and into the  
channel around the full circumference of the opening. Be sure it is  
completely seated in the channel for a proper seal.  
Do not use any lubrication on this gasket. This is a compression seal gasket,  
which is not affected by friction and does not require lubrication for proper  
closure of the housing.  
Attach the Zoom Control Guide Ring to the lens:  
.This is attached using the Velcro strip. Insure that the projected nub is  
directly on the bottom when you wrap it around the lens.  
The camera and tray are inserted in such a way that the nub of the Zoom  
Control Guide Ring is sandwiched between the two projections found on the  
lens port of the housing. All are pointed a downward direction. The Zoom  
Control is operated when camera is installed in housing and button # 2  
moved in an upward or downward direction.  
13  
Insert D-70 camera and lens in housing:  
Mount camera and lens on the removable tray, using the tripod screw.  
Slide the tray and camera into the housing tray slot. Make sure it is  
completely inserted.  
Slide the flash sync cord into the D-70's hot shoe.  
Align the housing controls with the corresponding buttons on the camera.  
Take caution to insure the flat sync cord does not get caught in the housing  
seal by storing the slack alongside the left side of the camera.  
Place housing back over front and align the complete mating surface of the  
housing and the gasket, forming a proper seal.  
Position all three latches over latch hooks in ready position.  
Close all three latches at one time. If it is not possible to close all three  
latches at the same time, close the bottom latch first, maintaining pressure  
on the other side. Then close the two side latches simultaneously.  
Inspect the gasket seal for proper closure. A complete seal can be visually  
confirmed by looking for the black line made by the gasket around the  
complete circumference of the housing.  
Take a Test Dive:  
Make the first dive without camera in housing.  
This will give you a chance to inspect the housing  
seal for proper closure. In this case, any mistakes  
will not result in the loss of the camera.  
Operate all controls under pressure in the water and  
inspect for watertight seal.  
Before all dives, immerse the housing in the camera  
rinse tank, and press all buttons, to visually inspect  
for any leakage.  
While descending on every dive carefully observe  
the housing. If you see any bubbles rising from it or  
water entering surface immediately while holding  
the lens port in a downward position. Once on dry  
land carefully open the housing, take out the camera  
and dry it off if any water is on it and check to see if  
there is any damage. Please inspect the housing,  
rinse it in fresh water, dry it out and then take a dive  
without the camera in the housing to check for leaks  
or other malfunctions.  
14  
Recommended Initial Camera Settings:  
Set D-70 on M (Manual) Exposure Mode  
o This is to keep the built-in flash from trying to pop up in  
low ambient light.  
o The Auto Exposure Modes are not always appropriate for  
underwater photography.  
Set camera to AF focus mode  
Use menu option to set camera for Focus Priority Release mode.  
Set Camera to Single Advance Mode  
Choose Matrix light meter. This will provide the most sophisticated light  
meter for evaluating complicated and fast changing ambient light conditions.  
o The Matrix meter in the D-70 is a 1,005 sensor RGB light  
meter, insuring the most accurate evaluation of the ambient  
light.  
Set ISO to desired sensitivity setting. Use ISO 200 for the least amount of  
noise (digital grain), when possible.  
Set personal preferences by using camera menus.  
Using External Strobes:  
Compatible Strobes include any that can use the standard Nikonos five pin TTL sync.  
These strobes will have to be used in the Manual Flash Exposure mode.  
Nikon Speedlights, such as the SB-600 and SB-800 can be used with the D-  
70 in the iTTL Auto Flash Exposure mode.  
Connect the strobe sync cord to housing's bulkhead sync port. On the side of  
the housing port notice a simple alignment indicator [dot] The 5 pin cord  
contains a small channel [groove] between two of the female pins of the  
cord. You must insert the cord into the port so the groove is aligned with the  
indicator of the housing. This assures proper alignment. Hold firmly in place  
while fastening locking screw. Tighten the collar to secure the cord in place.  
The O-ring on the end of the sync cord should be inspected, cleaned and  
lubricated in the same way the port O-ring was treated.  
Using different arms are and tray systems can be accommodated by  
attaching to the shoes on the top of the FD-70N’s handles, or by attaching to  
the base tray tripod mount. An adapter may be needed to physically mount  
the arms to the housing handles.  
15  
 
Care & Maintenance  
Before a dive:  
o Protect the FD-70N from sun and heat. This will reduce the  
possibility of fogging due to condensation of the warm,  
moist air inside the housing when immersed in the colder  
water. It also reduces the possibility of sun damage to the  
polycarbonate. An insulated camera bag is a good means of  
protection from overheating.  
o Protect the FD-70N from accidental impact damage. Secure  
the housing and camera in a safe location on the boat or in  
any vehicle, so it does not bounce around or bump into  
other cameras and housings. The insulated bag mentioned  
above should be padded for this reason. Do not leave the  
camera and housing in a camera rinse tank or bucket on the  
boat in route to the dive site. Rough conditions can cause  
impact damage and photo gear can often get tangled if too  
many systems are together in the tank.  
o Inspection of all user serviceable gaskets and O-rings  
should be a routine pre-dive check. Required maintenance  
for the main gasket involves cleaning only (if there is no  
damage requiring replacement). O-rings may require  
lubrication. Use the silicone grease supplied with the  
housing. Use only enough grease to lightly cover the O-ring  
to reduce friction as it is put into its place and the seal is  
made. Over-lubrication should be avoided and can result in  
debris accumulating on the O-ring, and compromise the  
seal.  
o It is highly recommended that the housing be immersed in  
the rinse tank or in shallow water before every dive and all  
its controls operated to visually confirm that it is watertight  
before descending to depth.  
After a dive:  
o Rinse the housing with a strong stream of fresh water. Let it  
soak for about 20 minutes to allow the water to dissolve  
any salt residues under the controls or in tight spaces.  
o Operate all the controls while the housing is soaking to help  
dislodge any salt residue that may be caught under or  
around the controls.  
o Dip the housing vigorously several times to agitate the final  
remains of salt from the narrow areas or around the controls.  
16  
 
o Detach sync cords, arms & brackets for overnight storage.  
This will greatly reduce the possibility of electrolysis and  
corrosion that can build up between similar metals on the  
housing.  
o Dry with a clean towel or allow drying naturally in a cool  
shady place.  
Traveling:  
o Use protective hard case when traveling to protect the  
camera and housing from impact damage.  
o If possible, do not check camera and housing case on  
airlines. Use a hard case that can fit under the seat or in the  
overhead compartment of aircraft, and hand carry.  
Annual Maintenance and Storage:  
o The housing’s main gasket and port O-ring should be  
replaced every year or more often if used frequently. The  
frequency of replacement depends on the user’s inspection  
of these seals and their condition at the time. If in doubt, it  
is always better to change them in order to not take the  
chance of flooding the housing.  
o The seals on each of the controls should be replaced every  
couple of years or more often if needed. The best indicator  
of the need for replacement is if the controls become harder  
to operate due to a build up of salt or corrosion.  
o Store housing in a cool, dry location when not traveling. It  
is recommended that the housing be stored with the two  
halves together, but not with the latching buckles closed.  
This will take the constant compression off the main gasket.  
It is also recommended that the housing is not stored with  
the port mounted.  
17  
Basic Shooting Techniques  
Practice handling the FD-70N on land.  
o Getting familiar with the location and movement of all the  
controls and how the changes in settings can affect your  
image is an important part of the process. It is better to  
learn the basics of the camera’s operation on land, rather  
than when first underwater. It is faster to operate the  
camera out of the housing and you will not have the limited  
time frame as you would if you were underwater.  
Focusing and Shutter release control.  
o Get used to operating this control on the camera in both  
half depress, and full depress movements. You will  
frequently depress the shutter release only half way to  
activate the exposure meter and auto focus to preview the  
shooting conditions and make setting changes. Once you  
get the feel for operating the camera control directly, you  
can then try it in the FD-70N, using the housing’s trigger  
control in the same manner.  
o It is highly recommended that a Diopter +4 be used with  
the standard kit lens and Macro lenses to help with the  
focusing and triggering of the housing  
Use the viewfinder eyepiece  
o
Compose and view exposure information display. It is very  
important that you become familiar with the information  
display in the viewfinder so you can make proper exposure  
settings and know what other settings have been made. You  
will use this often and it is good to become familiar with it  
before attempting to read it underwater. Also practice  
composing and focusing the camera by eye, before using it  
underwater to get the feel for this operation as well.  
18  
 
Changing Exposure Settings  
o Using the camera in its Manual (M) Exposure Mode gives  
you the ability to change either shutter speeds or apertures  
to control the exposure the way you want. Get used to  
making these changes while your eye is in the viewfinder  
and you are referencing the LCD display for guiding you in  
the exposure process. The command dial is set to change  
shutter speeds, and the sub-command dial is set to change  
apertures. Practice operating each of these controls so they  
become instinctive in operation.  
Familiarize yourself with the movements required  
o Utilizing each housing control to properly and efficiently  
change camera settings. Some controls only require a  
straight pushing movement, while others may require  
pushing and rotating simultaneously to operate.  
Using the camera’s light meter to determine ambient light  
o There are three light meters in the D-70; Matrix, Center  
Weighted, and Spot. Read the D-70 instruction manual for  
complete descriptions on each of these meters and when to  
use each. No matter which one you choose, they all help  
guide you to the proper shutter speed and aperture  
combination for proper ambient light exposure. Where you  
aim the meter is also important. In underwater photography,  
it is important to remember to aim the meter at the  
background water or "sky" to get the proper exposure  
information. It is often necessary to gather this information,  
make your exposure settings, and then re-compose the  
scene before shooting.  
Sometimes it is good to operate the AE-L button  
o When locking in the exposure value of the background  
before re-composing and taking the photo.  
The ISO Sensitivity setting on the camera  
o
This is the same as the film speed that photographers set  
on film cameras, with one small difference: There is no  
film. This setting is the equivalent of the film speed you  
would normally set. The higher the ISO sensitivity number,  
the more light is captured and the brighter the image.  
Higher ISO sensitivity numbers have more “Noise”, a term  
that is the digital equivalent of grain in higher speed films.  
Try starting out with a lower ISO sensitivity such as ISO  
200 if the lighting conditions permit.  
19  
Get close to you subject when shooting underwater  
o This will improve the effectiveness of your strobe in  
restoring lost color. It will also expand the sharpness of the  
image by reducing the amount of backscatter between the  
lens and the subject.  
Begin by choosing subjects  
o Those that are easy to approach and will not scare off  
readily when you approach. Choose subjects that will result  
in a large image size. This will make a more dramatic  
image.  
Change F/Stops and shutter speeds to “bracket” your exposures  
o This will give you a range of image exposures, from which  
you can choose the one that you like the best. It improves  
the probability of getting a good shot.  
Use flash all the time  
o This will restore the vivid colors lost through selective light  
absorption. Get to know the full manual power rating of  
your strobe, by shooting at a constant distance from an  
average reflective subject, and take several shots at  
different F/stops.  
Focus lock on your subject  
o Practice depressing the shutter release half way, and hold  
the focus until you are ready to record the image. If you are  
shooting a moving subject, it may be helpful to focus lock  
on a nearby part of the coral reef and wait for the subject to  
enter into your plane of focus.  
Take lots of shots of any subject or scene  
o It is important to vary each shot by changing exposure  
settings or composition. This will give you a good sample  
of shots from which to select the best one.

Camera Lenses and Ports  
The Fantasea FD-70N has an interchangeable port system that will accommodate a wide  
variety of SLR lenses for use underwater. These ports include:  
Standard Flat Port:  
This port will accommodate the 18-55 mm zoom lens in its wide angle  
18mm position. This lens is very popular and is the most common lens first  
purchased by D-50 owners. It does not include a manual zoom control. It is  
meant for use in only one position.  
60mm Macro Port:  
A very popular port for the workhorse 60mm micro Nikkor lens. This lens  
and port is the ideal combination for capturing the widest variety of fish  
identification portrait shots in a life-size reproduction.  
105mm Macro Port:  
The micro Nikkor is the best tool for capturing the tiny and shy marine  
subjects. When it is not possible to closely approach your subject, the lens  
will still offer life-size image reproduction, but with a longer working  
distance.  
5” Dome for Nikon 16 mm or Sigma 15mm:  
For distortion free use with wide-angle lenses, having a focal length of  
20mm or more. Some Zoom lenses can be used with this port, but may  
require a diopter to allow it to focus accurately.

The FD-70N includes a two-year limited warranty for defective parts which the  
manufacturer will replace.  
Flood Insurance:  
Every Fantasea housing includes a one-year flood insurance policy. Supplied by the  
Divers Equipment Protection Program (DEPP), this insurance policy acts as additional  
protection to the warranty and is good for one year. If your Fantasea housing  
experiences water leakage in this period of time you will be compensated for the loss of  
the camera. Only a small shipping charge will apply. All insurance policies should be  
activated at the time of purchase. All owners must complete the on-line product  
registration form by going to www.fantasea.com and go to the Customer Support tab and  
choose Product Registration; you will be taken to this page--  
http://www.fantasea.com/product_registration.asp where you can complete the form and  
register your housing purchase. Failure to register the product within 30 days of purchase  
will result in a shorter period of insurance coverage for your housing and may in the end  
cancel the flood insurance coverage all together. Also, you must keep the original sales  
receipt of your purchase, which must be submitted in the event of a claim: include it in  
the box and send it along with a photo copy of the bill of sale to Fantasea Products. To  
make a claim go to the same page and click the banner link: For DEPP anti flood
