PREPARATION OF THE PORTS

1. Select the correct port:

Depending on whether you've decided to shoot 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). See lens chart for the suggested port and acces-

sories.

Macro Port Extension Rings: If you intend to use a longer Macro lens than the Canon EF-S 60mm you will require an additional

extension ring. This extension rings ﬁt between the Macro Port and the housing to provide the extra space necessary for the longer

lens. See lens chart for the suggested port and accessories.

Dome Port Extension Rings: When using a wide angle or zoom lens, the Dome Port may require the uses of an extension ring to

closely match the optical center of both the dome and the lens.See lens chart for the suggested port and accessories.

In order to reduce glare, maximize contrast and offer physical protection to the dome, the use of a dome shade is highly recommended.

See lens chart for the suggested dome shade.

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 uptdated version of this lens chart, you can refer to the Lens Chart for the Aquatica 7D housing on

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 cleaner and the glass ports should be cleaned with lens cleaner. For more details be sure to 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 be sure to read

the section titled "Care and Maintenance: of the O-rings."

There are a number of gear options possible. Using the right gear (s) for your lens and correctly mounting them on the lens is a very

important step for a smooth housing operation. Follow the installation directions included with each gears carefully. The use of EF

mount lenses is mandatory.

A comprehensive list of the lenses supported and their required gears is available for download from our website. this housings lens

chart is the Type 2 for 1:6 type sensor cameras. For the latest uptdated version of this lens chart, you can refer to the Lens Chart on

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 need to install a closeup diopter on the

lens to correct the minimum focusing distance of the lens so that it will be able to focus on the virtually projected image created by the

dome. See lens chart for the suggested diopter, if required for your lens/port combination.

Gear installation:

Mounting the gear over the focus or zoom ring of the lens.

(a) For Slip-on gears (gears without mounting screws): just carefully slide the gear over the lens, if the ﬁt is too tight, some O-ring material

can be removed, make sure to not over do it

(b) For gears with mounting screws: slightly tighten the three set screws evenly. Tighten each screw approximately ½ a turn working

around the gear until all the three (3) screws are tightened, and the gear is concentric with the lens body. Be cautious to not over

tighten these screws, as this might bind the lens, thus restricting the rotation of the focus ring and/or damaging the lens. Conversely

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 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 motor.

Zoom lenses: When 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.
