2. Turn on the power switch of the flash, the ETTL (TTL) mark will
appear on the LCD panel and the flash will start charging.
3. Focus on your subject.
4. Check that the subject is located within the effective distance range
indicated on the LCD panel.
5. Press the shutter button, after the flash is fully charged.
Note: When the flash is fully charged, the ready light in the viewfinder
appears.
When the camera receives the appropriate exposure, the ETTL (TTL) mark on the LCD panel will appear
for 5 seconds. If this indication does not appear, the flash illumination is not sufficent for that situation.
Please re-take the picture at a closer distance.
The AF Auxiliary Light will turn on automatically as you focus on a dark area. Note: Effective distance is
up to about 0.7 to 9
meters (2.3-29.5 feet).
When the camera is set to ‘Creative Zone’ , the flash will be set to TTL / ETTL mode .
When the flash is fully charged, the flash mark will appear in the finder. If the shutter is released before
the flash is fully charged, the camera will take the picture at a slow shutter
speed with no flash.
USING FLASH IN OTHER CAMERA MODES (Except EOS700, 750, 850)
Shutter Speed Priority Setting
By selecting the Tv mode of the camera, you can set the shutter speed from 30sec. to 1/X sync speed.
When you set the desired shutter speed, the camera will select the appropriate aperture value for the
scene . If the subject is too light or too dark, the aperture value indicator will blink and show the limit values
(maximum or minimum aperture). In such as case, the camera proceeds to take a flash photograph at the
limit value. Thus, the main subject in the picture should be exposed correctly, but the background may
become under or over exposed.
Aperture Priority Setting
By selecting the Av mode of your camera, the camera will select the appropriate shutter speed for the scene . If
the subject is too bright or too dark, the shutter speed indicator will blink and show the limit (highest or slowest
shutter speed) value. The highest shutter speed will be limited to the camera’s normal flash synchronization
speed. In such a case, the camera proceeds to take a flash photograph at the limit value. Thus, the main
subject in a picture
should be exposed correctly, but the background may become under or overexposed.
When used with M Mode
You can set the desired aperture value and shutter speed from 30 seconds to the camera’s flash sync
speed. If the camera’s exposure requires more light to achieve correct exposure for the inputted values, the
flashgun will provide sufficient light to give the correct exposure, within the working range of the flashgun.
LIMITS OF CONTINUOUS SHOOTING
To prevent overheating of the flashgun’s circuitry, do not use your flash unit for at least 10 minutes after
continuously firing the flash for the number of exposures shown in the table below.
Mode Number of Flash Exposures
TTL, M(1/1,1/2) 15 Continuous Flash Shots
M(1/4, 1/8) 20 Continuous Flash Shots
M(1/16-1/32) 40 Continuous Flash Shots
Multi 10 Cycle
MANUAL FLASH OPERATION
Manual flash is provided for shooting subjects when the correct
exposure is difficult to obtain in the TTL mode. In the manual flash
mode, you can set the flash power level from 1/1 (full) to 1/128 power
in one step increments.
1. Set the camera’s exposure mode to M.
2. Press the MODE button on the flash unit to select M.
3. The
flash power output value blinks when you press the SEL button.
4. Press + or - button to set the desired flash power output.
