PREPARATION OF THE PORTS
1. Select the correct port:
Once you have decided on your type of photography for the dive, you will be installing either a flat Macro Port (product # 18426 or 18428), or a Dome
Port (Product # 18405, 18407, 18409 or 18410).
Refer to the AD7000 lens chart for the suggested port and accessories for the lens used.
Macro Port Extension Rings: Both the Macro Ports will accept the AF-D & AF-S Micro-Nikkor 60mm lens without extension. If you intend to use a longer
lens you will require an additional extension ring. These extension rings fit between the Macro Port and the housing and provide the extra space necessary
for the longer lens.
Dome Port Extension Rings: When using a wide angle or zoom lens, the Dome Port may require the uses of an extension ring to optimize the optical
center of both the dome and the lens.
In order to reduce glare, maximize contrast and offer physical protection to the dome, the use of a dome shade is highly recommended. Refer to the
AD7000 lens chart for the suggested port and accessories for the lens used.
A comprehensive list of the lenses supported and their required extensions and/or accessories is supplied at the end of this manual. For the latest up
-
dated version of this lens chart, you can refer to the AD7000 Type 4 Lens Chart at

2. Clean the port:
Dirt, grease or fingerprints on the port especially on the inside, can adversely affect the quality of the image. Acrylic ports should be cleaned with plastic
or acrylic safe cleaner and the glass ports should be cleaned with lens cleaner. For more details please read the section titled
“Care and Maintenance: of
the Ports.”
3. Lubricate the port O-ring seal:
Before using the port, remove the O-ring on the rear of the port and lightly coat it with silicone grease. For more details please read the section titled
“Care and Maintenance: of the O-rings.”
PREPARATION OF THE LENS
Depending on the lens used, there are a number of gear options possible. Using the right gear and correctly mounting it on the lens is primordial for
a smooth housing operation. Follow the installation directions included with each gears carefully. Since the aperture control on the Nikon D7000® is
achieved through the Sub-Command Dial, the use of AF types of lenses is mandatory.
A comprehensive list of the lenses supported and their required gears is supplied at the end of this manual. For the latest updated version of this lens
chart, you can refer to the AD7000 Type 4 Lens Chart at
www.aquatica.ca
Notes: If the camera is set in manual focus a focus gear must be mounted on the lens. If you are using a zoom lens with a zoom ring the camera must
be on auto focus, also note that if using a dome port you may be required to install a close up diopter on the lens to correct the minimum focusing dis
-
tance of the lens so that it will be able to focus on the virtual image created by the dome. Refer to the AD7000 lens chart for the suggested diopter, if one
is required for your lens/port combination.
Gear installation:
Mount the focus gear over the focus ring of the lens.
(a) For Slip-on gears (gears without mounting screws): Slide the gear over the lens and align the gear with the front of the lens focusing ring.
(b) For gears with mounting screws: Lightly tighten the three set screws evenly. Tighten each screw in small increments (approximately ¼ a turn each)
working around the gear until all the screws are properly tightened and the gear is concentric with the lens body.
CAUTION:
Do not over-tighten these screws, as this might bind the lens, thus restricting the rotation of the focus ring and/or damaging the lens. Con
-
versely under-tightening these screws might cause the gear to slip or loose alignment.
Rotate the focus ring several times to make sure it moves smoothly and the gear does not slip before closing the housing
WARNING:
If the lens is a not of the AF-S type, never attempt to operate it with the camera in autofocus mode and with a mounted focus gear engaged.
This might cause serious damage to your camera or to the lens. With standard AF lenses switch from manual to auto focus by lifting the focus knob and
the under laying disc (key # 10) rotate and position it so as to disengage the focus gear mechanism, then switch the AF/M lever (key # 16) to AF position.
Also avoid travelling with the zoom/focus gear attached as any impact will be directed at the sensitive zoom or focus mechanism
Zoom lenses: When using a zoom lens, the gear should be mounted on the zoom lens control. The Focus/zoom knob (key #11) then control the zoom
gears on the lens. Focusing of lens is achieved by using the camera’s autofocus system.
