Camera Model

The FD-70N is dedicated exclusively to the Nikon D-70 camera. The size and shape of the camera, plus the location of controls for alignment with housing controls requires this precision design. Together, the D-70 camera and FD-70N housing offer the best combination of advanced digital photography at an affordable price. No other camera may be used in the FD-70N housing.

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.

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

Note 1:

Note 2

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.

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.

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.

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.

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.

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.

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.

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.

• 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.

• 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.

Fantasea FD-70N Warranty

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.
