#6841 for Sony DSLR-A100

Congratulations on your purchase of an Ikelite Digital Camera Housing. Ikelite has over 40 years of experience in the underwater photographic and lighting market. Our products are designed and built in the USA by Ikelite for both the professional and amateur photographer. The clear housing permits instant visual inspection of the camera and all sealing surfaces as well as complete monitoring of controls and camera LCD screens. Ikelite Digital Housings are slightly negative in salt water for stability. This housing has been water pressure tested at the factory. Housing is pressure tested to 200’ (60m).

Before installing the camera in the housing we recommend setting the camera’s Monitor Display function to Manual. If the camera’s eyepiece sensor, located below the camera’s viewfinder, is set to Automatic the sensor will detect the housing and turn the Monitor Display off. See camera instruction manual.

To prepare the port for installation, remove the port o-ring

nd lightly lubricate it. The port seal is a side-to-side seal and

a requires the o-ring to be lightly lubricated for easy installation. Put a small amount of lubricant on your fingers and draw the o-ring through your fingers to lightly lubricate it. Do not

tretch the o-ring. Check that the lip of the port where the

s o-ring fits and the sealing surface on the housing are clean. Place the port, with o-ring into the housing’s port opening. Press the port firmly and evenly into the port opening while slightly rotating the port until you feel the port slide into place. Continue to push down on the port and push each port lock forward until it clicks into place. It may help to slightly rotate the port as you push in on the port lock. When the port lock clicks into place the Release Button will drop down against the port lock.

Check around the perimeter of the port seal to see that the o-ring is properly sealed and not extruded.

his housing offers two types of arm mounting systems. The

T top of the rubber handles utilize Ikelite’s Quick-Release Arm, available with the SA-100R Arm system.

The bottom of the rubber handles have a wing nut that accepts the Ikelite Tray Mount. The Tray Mount comes with the Ikelite SA-125 Arm system and the SA-100T Arm system.

1. Ikelite provides silicone lubricant with the housing. We recommend that you use only Ikelite lubricant 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.

PPrree--DDiivvee YYoouurr SSyysstteem

It is recommended that you take the complete system into a swimming pool before use in open water. This will give you a chance to become familiar with the handling and operation of your housing and strobe(s).

The buoyancy of the system will depend on the size and number of strobes used as well as the weight of the camera. Ideally the system should be slightly negative in the environment in which it will be used. If you need to add weight to the system, an optional lead weight is available. To add the lead weight remove the (2) screws from the bottom of the aluminum tray. Place the lead weight into the pocket of the aluminum tray and reattach.

FFLLAATT PPOORRTT

For standard, macro, and telephoto lenses.

Due to refraction flat ports reduce the angle-of -coverage of a lens and at the same time enlarge the image. This makes the flat port ideal when using standard, macro or zoom lenses to shoot small subjects. Note that if a port is long enough to accommodate the full length of a 1:1 macro lens, the lens may vignette when used at infinity. If access to the lens' full range is desired, then select a dome port instead.

Ikelite controls are designed to provide years of reliable service with minimal maintenance.

1. Push button controls require no maintenance other than rinsing in fresh water after saltwater use. If a push button control becomes difficult to push or if it sticks when depressed, soak the housing in luke warm fresh water. After a few minutes operate the push button. If this does not correct the problem, return the housing to Ikelite for maintenance.

2. Some of the controls have long shafts. These controls can be

pulled out, exposing the shaft (see drawing). To lubricate the control, gently pull on the knob until the stainless steel shaft is exposed. Lightly lubricate the shaft, then move the shaft in and out several times. This will lubricate the x’ring in the Ikelite control gland. This should be done before using the housing after a prolonged storage period, or once a week when the housing is in use.

3. Some of the controls have a short shaft and cannot be pulled out exposing the shaft for lubrication. In the unlikely event one

f these controls sticks or becomes difficult to operate you can

o remove the control from the housing and lubricate it, or return the housing to Ikelite for maintenance. To remove the control, loosen the set screw in the knob (allen wrench required);

emove the knob. If there is salt or dirt build-up on the exposed

r control shaft, clean the shaft. Open the housing and gently slide the control shaft out of the control gland. Clean and lightly lubricate the shaft, including the end of the shaft. Slide the shaft back into the control gland and gently slide it back and forth a few times without fully removing the shaft from the gland. Replace the knob, NOTE the flat area on the shaft, the set screw in the knob should tighten down against the flat area on the control so the knob does not turn on the shaft.

1. You should completely assemble and test your set-up in a wimming pool before using it in openwater.

2. It is a good idea to start each photo dive with a fully charged

battery(s) in the camera and strobes.

3. Before entering the water and as soon as you enter the water,

take a moment and check the housing to see that it is properly sealed.

4. Next, check to see if there are any bubbles on the face of the

port. If there are, take your finger and remove them. If there are bubbles on the lens port they can produce soft focus spots

RAW. Higher resolution setting are required for printing. High resolution images can easily be reduced in size with software and retain their original quality. A Low resolution image can be enlarged with software but much of the quality will be lost.

6. Digital images are usually transferred to the computer where

their appearance can be fine tuned. Many of the image manipulation programs make you think you can magically correct any image taken and make a good picture. One thing to be aware of is that if an image is overexposed that some of the color information in the file is missing. If the color is missing you cannot adjust it. If images are underexposed the color and detail may be there, it is just dark, and you can adjust it to some degree. So if you error in exposure it is better to have the image slightly underexposed than overexposed.

1. The number one rule in underwater photography is eliminate as much water between camera and subject as possible. Get as close as you can to the subject, then use the zoom. If you are using flash, subjects beyond 6 feet (1.8m)will not have much color.

2. Digital cameras have a slight lag time between when you press the shutter release button and the camera actually takes the picture. It only takes a slight amount of pressure to trip the shutter, if the shutter doesn’t trip immediately don’t push down harder on the shutter control as you may damage the camera. Hold the camera steady a second or two after pressing the shutter release button.

3. Do not shoot down on subjects as they will quite often blend into the background and be difficult to see in the photograph. Shoot subjects straight on or shoot up at a slight angle using the blue water as a contrasting background.

4. Underwater flash is used to restore the warmer colors filtered out by the water as well as to illuminate the subject.

5. For balanced lighting meter the background and set the camera aperture accordingly. Use TTL, adjust the strobe’s power settings, or move the strobe closer or farther away to properly expose the subject with the chosen camera aperture.
