TTL flash power compensation is provided in 9 steps
by half Ev increments for -2.0, -1.5, -1.0, -0.5, 0, +0.5,
+1.0, +1.5 and +2.0 Ev.
To set the Flash power compensation level rotate
the Power dial to the power level you desire.
Take a picture and the subject is shown with required lighting effect by keeping
the background exposure level as originally expected.
On some cameras, the TTL flash power compensation setting is provided in its
menu mode. When setting the TTL flash power compensation on your camera,
any compensation which is also set on the i40 will be counted in addition to the
compensation you selected in the camera’s menu mode. ( i.e. Having a +1
compensation set on the flash and a +1.3 compensation set in the camera would
yield a total compensation of +2.3 EV.)
With the latest TTL flash control system, the flash power level is always
automatically controlled by the camera for the most appropriate exposure. If
you wish, if you can soften or weaken the flash light, or give more light to the
subject without changing the environmental or background exposure effect.
The i40 can make it possible to quickly adjust the exposure for each particular
flash picture as needed.

(SF) for analogue flash system and Wireless remote for wireless remote.
All channels and groups RMT-M/ RMT-TTL/ RMT2-TTL may be used.
SD: In this mode, i40 synchronizes to the pre-flash system. The master flash is
to be set at TTL mode.
SF: In this mode, i40 synchronizes to the traditional single flash system. The
master flash is to be set at manual mode. Studio lighting system synchronizes
to this mode. This mode is also available for open flash, and for a standard
flash in the market.
Wireless Remote: For Sony system: In this mode, i40 synchronizes to the
wireless remote flash system. For remote All channel group RMT-M/

Fill-in flash and Light diffusing panel and Soft box
For short distance or portrait flash photography, if the light is not too sharp or
too strong to the subject, use the fill-in reflector flash or diffuse the light with the
supplied soft box.
If the subject is close (within 2 meters), turn the flash head 90°
upward and pull out the fill-in reflector as shown in the picture.
Take a picture as usual. A blink of fill-in flash freshens up the
subject in natural image.
This technology is also useful to eliminate the shadow on the
subject under the tree.
Place the Soft box onto the flash head to soften the light
output and reduce the shadows.
For portrait photography, pull out the light diffusing panel and
place it over the flash window as shown in the picture. The
diffusing panel makes the flash light softer.
Since the light diffusing panel expands the lighting area, it
covers the range of 16mm focal length lens.
This small blink of flash is also useful when taking a picture of
a baby without scaring him.
i40 supports shutter speeds up to 1/8,000 second.

NOTE
The HSS HIgh-Speed Sync setting you selected is memorized and reminds
unchanged when power on.
The HSS High-Speed Sync in Wireless mode are controled by master unit.
Please check your camera instruction manual.

Bounce lighting
When lighting a subject in front of the
wall, an unnecessary sharp shadow
may appear on the wall behind the
subject resulting in a disappointing
picture. Bounce the light off the ceiling
or wall to soften the light on the subject,
and the shadow will fade.
The flash head turns upward to 45° >60° >75° >90°.
Or mixing it upward/ sideways, you can set it in multiple directions as shown.
When the flash head stays at turning or tilting position, the zoom setting
position of i40 is automatically set at the position for a 50mm focal length lens.
The wall or ceiling in this case should be a flat surface and white color is
preferable. Colored ceiling or wall may reflect its color on the subject.
AF assist light emitter
Under a low light condition, or in a dark place, the AF assist light will
automatically emit the beam and illuminate the subject, so that the camera
can easily focus on the subject in darkness. The beam is however not
shown in the picture.
16
The flash head pans to both sides left and right in steps of 30° , 60° , 90°, 120°,
150° , 180° or to right 30°, 60°, 90°, 120°, 150°, 180°.

You do not need to set the flash unit for these functions.
Rear curtain synchronization
Auto Flash Bracketing
Slow Shutter Synchronization
All modes in i40 supports the slow
shutter synchronization.
The flash is controlled at a slow shutter speed to
trace the correct exposure on both the main
subject and back ground in low light conditions or at night.
The slow shutter speed produces a blurring effect of the subject and a
sharp flash beam freeze the moment. A combination of slow shutter
and flash light creates a motion image in the still picture.
All modes except Multiple flash mode are available for this sync.
system.
In rear-curtain sync., the flash fires just before the rear curtain close.
By using this function at slow shutter speeds, a moving subject will
appear with such moving marks behind. Refer the operation manual of
the camera for details.
i40 supports this function at A mode and TTL mode.
By setting this function on the camera, you will get continuous flash
pictures in the different exposure effect on each frame. Exposure
compensation ratio, number of picture frame is to be set on the
camera. Refer the operation manual of the camera for details.

Focus the subject.
Pre-flash is fired to pre-set the correct light amount
for the main subject.
Remarks: FEL only works on P, A, S & M mode.
(It depends on different type of camera, please check your camera instruction manual.)
When the back ground of the main subject is too bright, the camera’s expo-
sure reading system adjusts the flash light intensity for such back ground
condition and it results in the main subject being underexposed. Or in case
the main subject is not placed in the center of the viewfinder, the flash picture
may result in the aimed targeted subject being under or over exposed.
You can lock the correct flash exposure for the targeted subject in such a
condition. This flash exposure pre-set remains locked in, even if you change
the aperture or zoom the lens in and out. This mode can only be set on the
camera.
