On the side of the Auto Sensor is the

Auto Exposure Selector Dial.

Different cameras may require

different exposure values. Once the

correct exposure value is determined

for a particular camera, no further

adjustments should be necessary to

obtain acceptable flash exposures of

varying subjects within normal shooting ranges.

To determine the camera’s optimum Exposure Value we recommend

the following procedure. This procedure can be done above water.

Make sure the camera’s battery is fully charged and the AF35 flash

has fresh batteries. Assemble the AF35 flash and camera housing with

the flash deflector installed on the housing. Make sure the camera’s

uilt-in flash is set to fire on every shot and is fully charged. Turn the

AF35 flash mode dial to AUTO. Set the Auto Exposure Selector Dial to

5 as shown above. Position the camera and flash approximately 1m (3

feet) from a colorful subject.

Subject should not be all white or black

Take a picture, review the picture, if the picture is overexposed (light),

turn the Auto Exposure Selector Dial down to 4, if the picture is

underexposed (dark) turn the Auto Exposure Selector Dial up to 6.

Repeat this procedure until the optimum exposure is obtained. Once

the optimum Auto Exposure Value has been determined for that

camera, use that value anytime that camera is used with the AF35 in

the Auto Mode.

Repeat this procedure anytime a different camera is

used with the AF35 AutoFlash.

For advanced users, the Auto Exposure Selector Dial can be used for

exposure compensation while remaining in the automatic mode.

When the AF35 Autoflash is set in the Auto Mode the Auto Exposure

Selector Dial can be used to increase or decrease the flash intensity in

difficult lighting conditions.

the subject. If the subject is overexposed (light), then you can rotate

the mode switch clockwise to reduce the light output of the flash

until the desired exposure is obtained. The AF35 provides five

eductions in power in one-half f-stop increments from the full

power setting, (Fig 4), for example, shows the mode switch set to

minus 1-1/2 f-stops.

When the AF35 is in any manual setting the Auto Exposure Selector

ial setting has no effect on the flash output.

Switch the AF35 between Auto and Manual settings at any time.

he Ikelite AF35 Flash features a

ready/confidence light at the rear of the flash

that glows when the flash has recycled and is

ready to fire. When the recycle times range

between 10 and 15 seconds it is recommended

that fresh batteries be installed.

NNOOTTEE::

The AF35 flash will most likely recycle

faster than the camera’s built-in flash. Since

the camera’s built-in flash is required to trigger

the AF35 flash, make sure the camera’s built-in

flash has recycled and is ready to fire before

taking a picture.

When the AF35 fires in the Auto Mode and enough light reaches the

subject for proper exposure the ready light will glow green for about

2-3 seconds, then glow red. If the ready light does not glow green,

but glows red immediately after taking a picture, not enough light

reached the subject for proper exposure. Move closer to the subject

and take another picture and check the ready light.

The flash diffuser adds 10° to the

angle-of-coverage of the flash. The

diffuser is usually not required unless

a wide angle lens is being used. The

white diffuser features two

protruding tabs for use in installation

and removal. The tabs on the diffuser

should be positioned away from the

flash.

Place the diffuser over the front of the flash. Spread the two tabs

apart, insert the diffuser into the recessed front, and then rotate the

diffuser until it locks into position.

To remove the diffuser, bend one tab out towards the edge while

lifting simultaneously.

A lanyard can be attached to the diffuser by threading it through the

two holes.

When using dual AF35 AutoFlashes, determine the optimum Auto

Exposure Value for one AF35 Autoflash as described on page 6, then

set the same Auto Exposure Value on the second AF35’s selector dial.

Applies to Single or Dual Tray.

NOTE: The AF35 AutoFlash can ONLY be mounted to Ikelite

Compact Digital housing models DC-100 and DC-200.

Turn the housing so the tray mounting inserts on the bottom of the

housing are facing up. Place the tray across the bottom of the

housing, align the two outer holes in the tray with the mounting

inserts in the bottom of the housing. Insert the two mounting bolts

as shown below and tighten the bolts firmly to secure the tray to the

housing.
