Closing the Housing

Check to see that there is an o’ring

housing back

on the housing back and that it is

clean and in its proper location.

Guide the back onto the housing.

Take care to see that the TTL sync

cord does not obstruct the

installation. The o’ring should

touch the housing all the way

o’ring

around. There should be an

even gap all the way around

housing

between the housing and the

housing back.

Lift the lid snaps so they are

extended and place the lid snap

housing back

into the hook on the housing back.

To close the housing push

down on the lid snaps until

even gap

they snap into place. Lid

all 4 sides

snaps on opposite sides of

the housing should be closed

o’ring

at the same time. Be sure they

are down far enough to engage

housing

the lock.

Double check - Once the housing is closed, check the o’ring seal. Check the gap between the housing back and the housing, it should be even all the way around.

Look through the clear plastic back at the o’ring. You should see a darkened area where the o’ring is compressed against the housing back. If you do not see an even black compression seal all the way around the back, open the lid snaps, reseat the housing back and close the lid snaps. Visually check the seal again.

Lubricants

1. Ikelite provides silicone lubricant with the housing.

We recommend that you use only Ikelite lubricant on Ikelite products as some other brands may cause the o’ring to swell and not seal properly.

2. Use only enough lubricant to lightly cover control shafts and o’rings. Wipe off any excess lubricant with a clean cloth. Lubricant is not a sealant, it is used to reduce friction. Excessive lubricant can collect sand and dirt which may interfere with proper sealing.

CAUTION

Never use spray lubricants as the propellant ingredient can cause the plastic housing to crack.

Lens Port

Treat the glass in the lens port as a camera lens. After use, rinse and gently dry the lens port to avoid water spotting. To clean use a mild soap solution or lens cleaner.

Do not use alcohol or window cleaner on the Lens Port. This port does not accept external wide-angle lenses.

Checking Controls

Once the housing has been closed check to see that the housing controls line up with the camera controls.

Turn the camera on and operate each of the housing controls to get a feel for using the camera in the housing. Take a few pictures with the camera in the housing.

C A U T I O N :

Shutter Release

The camera's shutter release button operates in two stages. When depressed halfway it activates the camera's exposure meter and autofocus. When depressed fully it takes the picture. This half stop of the shutter release is more easily felt when using the camera out of the housing. But with some practice you can feel the half stop when the camera is in the housing. The camera's shutter release requires only minimal pressure to activate. With the additional leverage of the housing’s shutter release control you can put undue force on the camera's shutter release button. This can result in damage to the camera.

Digital cameras have a noticeable lag time between when you push the shutter release button and when the camera starts to do something. It is human nature to push harder when the camera does not instantly respond. Take several pictures with the camera in the housing, paying special attention to the feel of the shutter release. It only requires a very light touch.

NOTE:
The housing’s External TTL Strobe Connector’s waterproof cap
should only be removed when connecting an external strobe
with a sync cord. If no sync cord is connected to the housing
the connector’s waterproof cap must be in place before using
the housing in the water.	6

Optional Accessories

Back O'ring #0110

O'rings last for several years if properly maintained. (See Maintenance) Always carry a spare o'ring in case the housing o'ring becomes damaged or lost.

Using Flash

• The camera's built-in flash cannot be used to illuminate subjects underwater.

• Optional strobes do not work TTL with this camera.

Using DS Substrobes with the EV-Controller.

The Ikelite EV-Controller provides

10 manual power settings in half-stop increments with the DS51 or DS125 Substrobes. The EV-Controller can be triggered with the optional #4103.51 sync cord attached to the housing bulkhead.

External strobes expand lighting options to achieve the best lighting for different subjects. A second external digital strobe package can be added to fill shadows and produce more realistic photographs.
