Initial Camera Setup (before placing camera in housing)
- Insert a fully charged battery.
- Set the mode dial to “M” manual or “Av” aperture priority.
In “M” mode, set shutter speed to 1/60th second or 1/160th second for
fast moving subjects. Maximum shutter speed of 1/250th second
recommended to allow full power flashes from strobes. Set aperture to
F8 for general photography or F22 for macro photography (close-ups).
In “A” mode, adjust aperture as necessary for good exposure.
Set Image quality to JPEG L “20M”, or other desired setting.
- Set VF Grid Display to “Disable.”
- Set Image review to “8 seconds.”
- In Flash Control Menu:
Set Flash Firing to “Enable” and E-TTL II Meter to “Evaluative.”

Housing Conversion Circuitry
This housing contains Ikelite designed Conversion Circuitry. Once
attached, turn the strobe on first before turning on the camera.
When used with Ikelite DS Strobes the Conversion Circuitry provides
real TTL flash exposure with over and underexposure compensation
from +2 to -2 f-stops in 1/2 stop increments.
The Conversion Circuitry also offers Manual exposure control with 3 1/2
f-stops of underexposure control in 1/2 stop increments.
The Conversion Circuitry is powered by the Ikelite DS Strobe when
connected to the housing with the 4103.51 single or 4103.52 dual sync
cord. When using two strobes with the dual sync cord, the primary
strobe connected to the cord without the red band, must be turned on to
power the Conversion Circuitry. Always keep both strobes connected to
your dual sync cord underwater. Do not exchange your secondary
strobe for a dust cap which may not be waterproof.
Setting the Conversion Circuitry Strobe ID Switch
On the bottom of the housing camera tray is a
switch for setting the DS Strobe ID. Set the
switch to the Model of DS Strobe being used.
When using dual strobes of different models
such as a DS51 and a DS161, set the ID
switch to DS51 or the smaller strobe.

-Mode and Compensation Buttons
The Conversion Circuitry default is set to TTL. To switch between TTL and
Manual Modes, depress both Mode Buttons at the same time and keep
them depressed until you see the desired Yellow LED Mode illuminate.
-TTL Mode (indicated when the yellow LED directly below TTL is
illuminated). TTL Mode is the default setting. When the DS Strobe is
powered ON, the yellow TTL LED will illuminate. None of the Red LEDs
will illuminate. This indicates that no (+) plus or (-) minus compensation is
selected. Depress the Mode buttons to select +/- compensation. Note that
the TTL +/- compensation values are in the yellow bar with the heading
TTL.
-Manual Mode (indicated when the yellow LED directly below the M is
illuminated). When the Manual Mode is selected, the Red LED directly
below the F (full power) will illuminate. Note that the Manual minus (-)
compensation values are in the black bar with the heading M. Set DS
Strobe to TTL mode. This will allow the strobe power to be varied in
manual mode.

DS50 and DS125 Strobe Compatibility
- Older DS50 Strobes with Serial Number below 63,850 can NOT be
updated to operate correctly with the latest TTL conversion circuitry.
Older DS50 Strobes with Serial Number between 63,850 and 69,999
require upgrade of electronics to operate. Cost of update depends on
strobe circuitry. Strobe must be returned to Ikelite for evaluation to
provide an estimate of upgrade cost.
- Older DS125 Strobes with Serial Number below 2,500 can NOT be
updated to operate correctly with the latest TTL conversion circuitry.
Older DS125 Strobes with Serial Number between 2,500 and 4,999
require upgrade of electronics to operate. Cost of update depends on
strobe circuitry. Strobe must be returned to Ikelite for evaluation to
provide an estimate of upgrade cost.

Final 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 the housing.
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.
Closing the Housing
1. Place housing face down in your lap.
2. Check to see that there is an o-ring on
the housing back that is clean and in its
proper location.
3. Guide the back onto the housing. The
o-ring should touch the housing all the
way around. There should
be an even gap all the way around
between the housing and the housing
back.
4. Lift the lid snaps so they are extended
and place the lid snap into the
corresponding hook on the housing
back.
5. To close the housing, push down on the
lid snaps until they snap into place. Lid
snaps on opposite sides of
the housing should be closed
at the same time. Be sure they
are down far enough to engage
the lid-snap lock.

feel for using the camera in the housing. Take a few test shots on land.
Attaching a Sync Cord to the Housing
The ousing Bulkhead is designed to accept only an Ikelite 5-pin TTL
Sync Cord.
1. Lightly lubricate the Sync Cord O-ring. Use ONLY Ikelite lubricant
(supplied with housing).
2. Remove Bulkhead Cap from ousing Bulkhead.
3. Line up the Sync Cord Pins with the corresponding Bulkhead
receptacles. Gently insert Sync Cord into Bulkhead. DO NOT force this
installation. If the Sync Cord does not seat properly inside the Bulkhead,
the pins and receptacles are i properly aligned (repeat Step 3).
4. Tighten the Knurled Nut snugly using your Index finer and thumb. DO
NOT use pliers or other tools to tighten the Knurled Nut.
Always remove the Sync
Cord from your ousing

Installing the Zoom Clamp & Gear Sleeve On the Type 1 Lenses
The Zoom Clamp has springs so it can be expanded to fit over the
Zoom Ring of the lens - figure C, page 15.
Install the Zoom Clamp with the extension tabs toward the rear element
of the lens. After installing the Zoom Clamp and Gear Sleeve - figures D
& E, page 16, install the Lens Port and rotate the Zoom Ring on the
lens. If the Zoom Ring and Gear Sleeve do not mesh properly, install the
rubber strips (supplied) to the inside diameter of the Zoom Clamp as
shown in figure F, page 16.
Two thicknesses of rubber strips are provided. Start by installing the
thinnest rubber strips. If the Zoom Clamp still is not tight enough and
meshes improperly with the Gear Sleeve, use the thicker rubber strips.
Reinstall the Zoom Clamp, Sleeve. Mesh Gear Sleeve teeth with Black
ousing Drive Gear, figure G, page 18, and then install the Lens Port.
After installing the port, pages 19 & 20, rotate the housing Zoom Control
Knob to see that the Gear Sleeve is properly rotating the lens Zoom Ring.

Installing the Zoom Clamp & Gear Sleeve On Type 2 Lenses
Due to the larger diameter lens opening on Type 2 lenses, the Zoom
Clamp and Gear Sleeve need to be installed from the rear (bayonet end)
of the lens. Use the housing Lens Release Control and remove the
camera lens from the camera body, after the camera and lens have
been installed in the housing.
Place the Gear Sleeve in the housing opening as shown.
Install the black Zoom Clamp on the Lens Zoom Ring and lower the lens
into the housing opening. Make sure the Zoom Clamp grooved tabs
align with the Gear Sleeve ribs. If necessary, install rubber strips to
expand the Zoom Clamp so it meshes properly with the Gear Sleeve.

Manual Focusing
Ikelite DSLR housings are designed for auto-focus DSLR
cameras and lenses. Manual focusing is not recommended. In some
cases, if you desire to manually focus a lens, the zoom clamp must be
moved onto the lens Manual Focus Ring and you must use the housing
Zoom Control K nob to manually focus. This will result in loss of zoom
capability.

Installing Zoom Clamp/Sleeve on Type 2 Lenses - continued
Before installing the lens port and checking operation, make sure the
teeth on the Gear Sleeve mesh with the teeth on the housing Drive Gear,
shown below. When the port is installed, pages 19 & 20, it will lock the
Gear Sleeve in place. After installing the port, rotate the housing Zoom
Control Knob to see that the Gear Sleeve is properly rotating the Lens
Zoom ring.

Installing the Port
There are four port locks on the
front of the housing, see figure
G, page 18. Each port lock has
a Release Button. Lift the
release button and slide each
Port Lock away from the port
opening. In the unlocked
position, the Release Button will
remain in the up position as
shown.
To prepare the port for
installation, remove the port o-ring and lightly lubricate it. The port seal
is a side-to-side seal and requires the o-ring to be lightly lubricated for
easy installation. Put a small amount of lubricant on your fingers and pull
the o-ring through your fingers to lightly lubricate it. Do not stretch the
o-ring. Check that the lip of the port where the o-ring fits and the sealing
surface on the housing are clean. Place the port, with o-ring, into the
housing port opening. Press down on the port firmly and evenly until you
feel the port slide into place. Continue to push down on the port and
push each port lock forward until the lock fully engages. It may help to
slightly rotate the port as you push in on the port lock. Visually inspect
each port lock and confirm that the Port Lock Release Button is seated
flush against the Port Lock Body. Do not rely on an audible "click" to
indicate that the lock is engaged.
Check around the perimeter of the port seal to see that the o-ring is
properly sealed and not extruded, figure 2, page 20.
It is NOT necessary to tighten housing port locks after installing a port.
Port locks are factory adjusted. Slight port movement is normal after port
locks have been closed and port has been secured to the housing.

seated as shown in figure 1 and not
extruded as shown in figure 2.
Fig. 1
Fig. 2
Caution:
After installing the lens and port, turn the Zoom Control knob on the
housing. If the Zoom Control is difficult to turn, the gear sleeve may be
warped. If necessary, reduce or omit any rubber installed on the Zoom
Clamp, figure F, page 16. If the Zoom Clamp is still warped, use of the
5509.28 package may be required, see page 14.
Lens Ports
A lens port must be secured to the housing before entering the water.
Ikelite DSLR housings DO NOT come with a lens port. You must select
the correct port for each lens you will be using underwater. To assure
water-tightness, submerge the housing with port attached into a bathtub
or shallow water without the camera installed. This will confirm correct
installation of the port to the housing. For complete lens port information
and compatibility with your Ikelite system, go to ikelite.com.
