PREPARATION OF THE PORTS
1. Select the correct port:
According to your shooting requirement (macro or wide angle photography), you will be installing either a flat Macro Port (product # 18426,
18428 or 18429), or a Dome Port (Product # 18405, 18407, 18409 or 18410).
Refer to the Canon Type 4 lens chart for assistance in selecting
the right port and accessories for your needs.
Macro Port Extension Rings:
Some Macro lens may require an additional extension ring. These extension rings are inserted between
the Macro Port and the housing to provide the necessary space for these longer lenses.
Dome Port Extension Rings:
Frequently, when using a wide angle or zoom lens, your Dome Port may require the uses of an extension
ring to align its optical center with that of the lens being used. These port extension rings are inserted between the Dome Port and the
housing.
In order to reduce glare, maximize contrast and offer physical protection to the dome, the use of a dome shade is highly recommended.
See the Canon Type 4 lens chart for the suggested dome shade.
A comprehensive list of the lenses supported and their required extensions and/or accessories is supplied along with this manual. For the
latest updated version of this lens chart, you should refer to the Canon Type 4 Lens Chart available from our website:

2. Cleaning 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 cleaner and the glass ports should be cleaned with lens cleaner. For more details please refer to 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 Aquatica O-ring Lubricant. For more details please
refer to the section titled “
Care and Maintenance: of the O-rings.

PREPARATION OF THE LENS
Aquatica has a wide selection of Focus and Zoom gears to accommodate the most popular lenses used in underwater photography. Correctly
mounting and securing these gears on a lens is elementary for a smooth operation. Follow the installation directions included with each
gears carefully. The use of EF type’s lenses is mandatory.
A comprehensive list of the lenses supported and their required gears is supplied along with this manual. For the latest updated
version of this lens chart, you can refer to the Canon Type 4 Lens Chart:

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, unless you are using one of the dedicated port or extension ring with a focusing knob, also
noteworthy is that some wide angle lens may require a close up lens (Diopter) when used behind some dome port, the purpose of the
close up lens is to correct the minimum focusing distance of the lens so that it will be able to focus on the virtual image created by the
dome port.
Refer to the Canon Type 4 lens chart to confirm if one is needed and for the suggested close up/diopter strength if required.
Gear installation:
Your Focus or Zoom gear packaging contain the instruction for properly mounting the gear onto the lens, please follow packaging instruction.
Once installed, 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 USM 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 lens focusing mechanism.
Zoom lenses:
if using a zoom lens, the gear should be mounted on the zoom lens control. The housing focus control then becomes
the
zoom control. Focusing of lens is achieved by using the camera’s autofocus system or by a dedicated knob on the port or port extension.
