Power Management

Use ON/OFF Power Switch to power the flash unit on or off. Turn off it will not be used for an extended period of time. Setting as transmitter flash, it will turn the power off automatically after a certain period (approx. 90 seconds) od idle use. Pressing the camera shutter halfway or pressing any flash button will enter sleep mode after certain period (adjustable, 60 minutes by default) of idle use. Pressing any flash button will wake it up.

Disabling Auto Power Off function is recommended when the flash is used off camera. (C.Fn-STBY)

Receiver Auto Power Off Timer is set to 60 minutes by default. Another option “30 minutes” is available (C.Fn-RX STBY)

Flash Mode—E-TTL AutoFlash

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.

ETTL Mode

Press Mode Selection Button to enter E-TTL mode. The mode LCD panel will display.

  • Press the camera release button halfway to focus. The aperture and effective flash range will be displayed in the viewfinder.
  • When the shutter button is fully pressed, the flash will fire pre-flash that the camera will use to calculate exposure and flash output the instant before the photo is taken.

FEC: Flash Exposure Compensation

With FEC function, this flash can adjust from -3 to +3 in 1/3 stops. It is useful in situations where minor adjusting of the TTL system is needed based on the environment.

FEC Setting:Godox TT685II-C Flash for Canon Cameras-
fig-20

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. This function helps get correct exposure especially in shooting moving objects or when environmental lights are complex.Godox
TT685II-C Flash for Canon Cameras-fig-21

  • FEB will be cancelled after three photos are taken.
  • For best result, set the camera drive mode to “single” and ensure the flash is ready before shooting.
  • FEB can be used with FEC and FEL.

You can prevent the FEB from being cancelled automatically after three photos are taken. (C.Fn-FEB ACL)

FEL: Flash Exposure Lock

FEL can lock the correct flash exposure setting for any part of the scene. With displayed on the LCD panel, press the camera’s button. If the camera does not have the button, press <*> button.

  1. Focus the subject
  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 in retained in memory.
  • “FEL” will display on the viewfinder for 0.5s.
  • The camera flash will fire a preflash and lock the flash exposure setting once the button is pressed.
  • 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.
  • If is not displayed on the LCD panel, FE lock cannot be set.
  • If the subject is too small, FE lock might not be very effective.

High-Speed Sync

High Speed Sync (FP flash ) enables the flash to synchronize with all camera shutter speeds. This is convenient when you want to use aperture priority for fill-flash portraits.Godox TT685II-C Flash for Canon Cameras-
fig-24

  • If you set a shutter speed that is the same as or slower than the camera’s maximum flash sync speed, < > will not be displayed in the viewfinder.
  • With high-speed sync, the faster the shutter speed the shorter the effective flash range.
  • To return to normal flash, press button again. The < > will disappear.
  • Multi flash mode cannot be set in high-speed sync mode.
  • Over-temperature protection may be activated after 30 consecutive high-speed sync flashes.

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 2 button so that < > is displayed on the LCD panel.

M: Manual Flash

The flash output is adjustable from 1/1 full power to 1/256th power in 1/10th stop increments. To obtain a correct flash exposure, use a hand-held flash meter to determine the required flash output.Godox TT685II-C Flash for Canon
Cameras-fig-30

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. This is useful when cameras have pre-flash function. Whit this function the flash will ignore a single “preflash” from the main flash and will only fire in response to the second, actual flash from the main unit.

  • S1 and S2 optic triggering is only available in M manual flash mode.

Multi: Stroboscopic Flash

With stroboscopic flash, a rapid series of flashes is fired. It can be used to capture multiple images of a moving subject in single photograph. You can set the firing frequency (number of flashes per sec. expressed as Hz), the number of flashes, and the flash output.

Press button so that is displayed.

Set the flash frequency and flash times.

  • Press the Function Button to select the flash times. Turn the Select Dial to set the number.
  • Press the Function Button to select the flash frequency. Turn the Select Dial to set the number.

Turn the Select Dial to choose desired flash output. After you finish the setting, press Set Button and all the settings will be displayed.

Calculating the Shutter Sped

During stroboscopic flash, the shutter remains open until the firing stops. Use formula below to calculate the shutter speed and set it with the camera.

Number of Flashes / Flash Frequency = Shutter Speed

For example, it 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. After 10 times, allow the camera flash to rest for at least 15 minutes. If you try to use stroboscopic flash more than 10 times in succession, the firing might stop automatically to protect the flash head. If this camera happens, allow at least 15 minutes rest for the camera flash.

  • Stroboscopic flash is most effective with a highly reflective subject against a dark background.
  • Using a tripod and remote control is recommended.
  • A flash output of 1/1 and 1/2 cannot be set for stroboscopic flash.
  • Stroboscopic flash can be used with “bulb”
  • If the number of flashes is displayed as “–”, the firing will continue until the shutter closes or the battery is exhausted. The number of flashes will be limited ah shown by the following table:

    • Please replace the battery (the flash trigger is recommended to use 1.5V disposable alkaline battery).

Other Applications

Sync Triggering
The Sync Cord Jack is a Φ2.5mm plug. Insert a trigger plug here and the flash will be fired synchronously with the camera shutter.

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 the 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.

  • If you find he auto assist beam does not light up, this is because the camera has got a correct autofocus.Godox TT685II-C Flash for Canon Cameras-fig-57

Bounce Flash

By pointing the flash head toward a wall or ceiling, the flash will bounce off the surface before illuminating the subject. This can soften shadows behind the subject for a more natural-looking shot. This is called bounce flash. To set the bounce direction, hold the flash head and turn it to a satisfying angle. Godox TT685II-C Flash for Canon Cameras-fig-58

  • If the wall or ceiling is too far away, the bounced flash might be too weak and result in underexposure.
  • The wall or ceiling should be a plain, white color for high reflectance. If the bounce surface is not white, a color cast may appear in the picture.
