The product can be used in combination with the following accessories sold separately, so as to achieve best photography effects: FT-16S power & trigger control, Car charger, Mini softbox, White & Silver reflector, Honeycomb, Color gels, Snoot, etc. Attaching to a Camera 1. Attach the Camera Flash. Slip the camera flash’s mounting foot into the camera’s hotshoe all the way. 2. Secure the Camera Flash. Rotate the lock ring on the mounting foot until it locks up. 3. Detach the Camera Flash.
This flash has three flash modes: E-TTL, Manual (M), and Multi (Stroboscopic). In E-TTL mode, the camera and the flash will work together to calculate the correct exposure for the subject and the background. In this mode, multiple TTL functions are available: FEC, FEB, FEL, HSS, second curtain sync, modeling flash, control with the camera’s menu screen. * Press Mode Selection Button and three flash modes will display on the LCD panel one by one with each pressing.
3. Press button again to confirm the setting. FEB: Flash Exposure Bracketing You can take three flash shots while automatically changing the flash output for each shot from -3 to +3 in 1/3rd stops. The camera will record three images with different exposures: one exposed according to camera calculations, one over-exposed and another under-exposed. Over and under exposure amount is user adjustable.
2. Press the button. * Aim the subject at the center of the viewfinder and press button. * The camera flash will fire a preflash and the required flash output for the subject is retained in memory. * Each time the button is pressed, a preflash will be fired and a new flash exposure setting will be locked. z If the subject is too far away and underexposure, the < > icon will blink in the viewfinder. Move closer to the subject and try the FE lock again.
Second-Curtain Sync With a slow shutter speed, you can create a light train following the subject. The flash fires right before the shutter closes. Press function button 4 < > button so that < > is displayed on the LCD panel. M: Manual Flash The flash output is adjustable from 1/1 full power to 1/128th power in 1/3rd stop increments. To obtain a correct flash exposure, use a hand-held flash meter to determine the required flash output. 1. Press button so that < > is displayed. 2.
Optic S1 Secondary Unit Setting In M manual flash mode, press < S1/S2> button so that this flash can function as an optic S1 secondary flash with optic sensor. With this function, the flash will fire synchronously when the main flash fires, the same effect as that by the use of radio triggers. This helps create multiple lighting effects. Optic S2 Secondary Unit Setting Press < S1/S2> button so that this flash can also function as an optic S2 secondary flash with optic sensor in M manual flash mode.
Calculating the Shutter Speed During stroboscopic flash, the shutter remains open until the firing stops. Use the formula below to calculate the shutter speed and set it with the camera. Number of Flashes / Flash Frequency = Shutter Speed For example, if the number of flashes is 10 and the firing frequency is 5 Hz, the shutter speed should be at least 2 seconds. To avoid overheating and deteriorating the flash head, do not use stroboscopic flash more than 10 times in succession.

speedlites e.g. 580EXII, 600EX-RT and commanders of Canon cameras e.g. 7D/60D/600D. You can set up two to three slave groups for E-TTL II autoflash shooting. With E-TTL II z autoflash, you can easily create various lighting effects. Any flash settings (of flash exposure compensation, high-speed sync, FE lock, FEB, manual z flash, Multi flash) on the master unit will be automatically sent to the slave units.

Using Automatic Wireless Flash with a Single Slave Unit 1、Master Unit Setting ● Attach a TT685C camera flash on the camera and set it as the master Unit. ● As a master unit, TT685C can control Canon speedlites e.g. 580EXII, 600EX-RT via wireless. 2、Slave Unit Setting ● Set the other camera flash as the wireless slave unit. ● As a slave unit, TT685C can receive wireless signals of Canon speedlites e.g. 580EXII, 600EX-RT and commanders of Canon cameras e.g. 7D/60D/600D. 3、Check the communication channel.
distance from the master unit. Using Automatic Wireless Flash with Multiple Slave Units When stronger flash output or more convenient lighting operation is needed, increase the number of slave units and set it as a single slave unit. To add slave units, use the same steps as setting “automatic wireless flash with a single slave unit”. Any flash group can be set (A/B/C).

3、Setting . ● Press Function Button 2 < > so that is displayed. 4、Setting flash ratio. ● Press Function Button 3 < >. ● Turn the Select Dial to set the amount of flash ratio and press button to confirm. 5、Taking the picture. ● The slave units will flash according to the flash ratio. Auto Flash Shooting with Three Slave Unit 1、Setting the slave group . ● Use the same method of step 1 to set the slave unit of flash group. 2、Setting .
● When setting < RATIO A:B C >, group A, B and C will fire a flash synchronously; when setting< RATIO A:B >, group C will not fire a flash. ● If shooting under the situation that group C is toward the main shooting subject, over exposure might occurred. ● In some EOS film cameras that support E-TTL autoflash, you cannot perform multiple flash wireless shooting with a flash ratio setting. ● The flash ratio of 8:1 to 1:1 to 1:8 is equivalent to 3:1 to 1:1 to 1:3 (1/2 step increment).
A/B/C（RATIO A：B：C）。 3、Setting flash output. ● Press Function Button 3 < >. Turn the Select Dial to set the flash output of the groups. Press button to confirm. 4、Taking the picture. ● Each group fires at the set flash ratio. ● When ALL < RATIO OFF > is set, set A, B or C as the firing group for the slave units. ● To fire multiple slave units with the same flash output, select ALL < RATIO OFF > in step 2.
Wireless Flash Shooting: Radio (2.4G) Transmission Using a flash (master/slave) with a radio transmission wireless shooting function make it easy to shoot with advanced wireless multiple flash lighting, in the same way as E-TTL II autoflash shooting. The basic relative position and operation range are as shown in the picture. You can then perform wireless E-TTL II /ETTL autoflash shooting just by setting the master unit to .
You can divide the slave units into two or three groups and perform E-TTL II/E-TTL autoflash while changing the flash ratio (factor). In addition, you can set and shoot with a different flash mode for each firing group, for up to 5 groups.
Other Applications Wireless Control Function The flash unit is built in with a Wireless Control Port so that you can wirelessly adjust the power level of the flash and the flash triggering. To control the flash wirelessly, you need a FT-16S remote control set (on-camera and on-flash). Insert its receive end into the Wireless Control Port on the flash and insert the transmit end into the camera hot shoe.
Auto Focus Assist Beam In poorly-lit or low-contrast shooting environments, the built-in auto focus assist beam will automatically light on to make it easier for autofocus. The beam will light up only when autofocus is difficult and get out as soon as the autofocus becomes correct. If you want to turn off the auto focus assist beam, set the “AF” to “OFF” on the C.Fn settings. z If you find the auto focus assist beam does not light up, this is because the camera has got a correct autofocus.
Creating a Catchlight With the catchlight panel, you can create a catchlight in the subject’s eyes to add life to the facial expression. 1. Point the flash head upward by 90°. 2. Pull out the wide panel. The catchlight panel will come out at the same time. 3. Push the wide panel back in. * Push in only the wide panel. * Follow the same procedures as for bounce flash. z Point the flash head straight ahead and then upward by 90°. The catchlight will not appear if you swing the flash head left or right.
Using the Wide Panel Pull out the wide panel and place it over the flash head as shown. The flash coverage will then be extended to 14 mm. * The catchlight panel will come out at the same time. Push the catchlight panel back in. * The < ZOOM/C.FN > button will not work. Low Battery Warning If the battery power is low, < > will appear and blink on the LCD panel. Please replace the battery immediately. C.
