Start Action Camera Flashlight in 9 Steps!

The action camera flashlight is an excellent device for recording extreme adventures. It can be attached to several accessories such as your helmet, allowing you to document your mountain biking trips. You can also use an action ca to make a recording of your favourite sports. Although many people admire this fantastic device, only a few are aware of its history. It is important to have some knowledge about the invention of action camera flashlight as knowing its history can enhance your expertise in using this valuable device.

*The illustrations and screenshots in this article use the EOS 77D and Speedlite 430EX III-RT. Other cameras and Speedlite models might feature different menu screens and operating procedures, so please refer to the relevant user manuals for more details.

Step 1: Mount the flash on the camera and turn on the power

Insert the external flash into the hot shoe on top of the camera. Once fully inserted, slide the mounting foot lock lever to lock it into place. Switch on the power supply of the camera, followed by that of the flash. Turn off the power of the flash before you attach or detach it from the hot shoe.

Then, slide the mounting foot lock lever until a click sound is heard, indicating that it is locked. Power on the camera, then power on the flash. To detach the flash from the hot shoe, slide the lock lever in the reverse direction while pressing the lock release button.

Step 2: Reset the flash settings

You can easily reset the flash functions and Custom Functions of the external Speedlite with the [Flash control] menu. Carrying out a reset for every new shooting session helps to avoid accidentally using settings from your previous shoot.

Reset the flash function settings


Mount the flash onto the camera, then turn the mode dial to set the shooting mode to one of the Creative Zone modes, such as Program AE (P). Press the MENU button on the camera and select [Flash control] from the shooting menu.


Select [Clear external flash set.]. On the next screen, you will see a prompt confirming that you want to “Clear all external flash settings”. Select [OK].

*On the EOS 1300D/EOS M3: From the [Flash control] menu, go to [External flash func. setting]. Press the “DISP” button to select the [Clear Speedlite settings] function. Select [OK].

Reset the flash custom function settings

On the [Clear settings] menu, select [Clear ext. flash C. Fn set.]. On the next screen, you will see a prompt confirming that you want to “Clear all Speedlite C. Fn settings”. Select [OK].

*On the EOS 1300D: On the [Flash control] menu, select [Clear ext. flash C. Fn set.]. Select [OK].

Step 3: Select a flash mode

You can choose to set the flash mode either using the camera or using the flash unit. (On the Speedlite 270EX II, set the mode using the camera.) There are two possible modes: E-TTL (Evaluative Through The Lens) mode or Manual flash mode.

E-TTL II flash metering mode is the default mode on Speedlites. In this mode, the flash is fired automatically, and the flash output metering is automatically determined by the camera. This is ideal for when you want to take a quick picture using the exposure that the camera’s metering system decides.

Manual flash mode (M mode) allows you to set your preferred flash output level. You can use it when you need more control over flash output, as is necessary for professional-level action camera flashlight. One example is when you want to make use of multiple flash units to create shadow effects.

On the camera


Go to [Flash control]→[External flash func. setting]. The default mode is “ETTL” mode (or more specifically, E-TTL II flash metering mode), which fires the flash automatically.


Select the “ETTL” icon to display the [Flash mode] menu. Use Manual flash mode if you want to manually set the flash output level.

*On the EOS 1300D: on [External flash func. setting], select [Flash mode] and then the appropriate mode.

On the flash

Tip 1: In Manual flash mode, you can adjust the flash output level

In Manual flash mode, the “Flash output level” item will appear. (It is not displayed in the E-TTL flash mode). The manual flash output guide number is indicated as “1/1” for full output of the attached flash unit, “1/2” for half the flash output, “1/4” for a quarter of the full flash output and so on. This is different from the flash exposure compensation function present in the E-TTL flash mode (see Step 8).

On the camera

To set the flash output level, select the “Flash output level” item. Numbers to the right result in stronger light from the flash. Numbers to the left result in weaker light. “1/1” means full output from the flash.

On the flash

In Manual flash mode, press the “SEL/SET” button, and use the Select dial or the cross keys to scroll to the flash output item (red box). Turn the dial to select the flash output, and then press the “SEL/SET button again to confirm the selection. Alternatively, press the “+/-“ button to call up the flash output item. Note that if you are in E-TTL flash mode, the flash compensation item will be displayed instead.

Tip 2: With Speedlite 430EX III-RT and Speedlite 600EX II-RT, you can configure settings for multiple flash units

When you get more experienced with action camera flashlight, you might want to try shooting with multiple flash units. The Speedlite 430EX III-RT and Speedlite 600EX II-RT are additionally equipped with an Individual group control (Gr) mode, which lets you configure settings for multiple flashes. The steps are the same as those for setting E-TTL and the Manual flash mode, and they can be performed on either the camera or the flash unit.

Step 4: Select a shooting mode

Select the shooting mode suited for the intent and contents of the photo you wish to take. action camera flashlight can be used in any shooting mode.

Turn the Mode Dial and select the desired shooting mode. Select Shutter-priority AE when you wish to capture moving subjects without motion blur, or make use of motion bur to express movement. Select Aperture-priority AE if you wish to control the depth of field to make use of the bokeh effect, or to carry out deep focusing. Make a choice based on your intent.

Tip: You can use E-TTL flash with any shooting mode, but flash compensation might not be possible in some modes

You can carry out flash photography in E-TTL mode, with in any shooting mode in the Basic Zone and Creative Zone of the camera. However, flash compensation (see Step 8) is not possible in the Full Auto and scene modes. Thus, Program AE, Aperture-priority AE and Shutter-priority AE are easier to use if you want more control over your photo. On the other hand, the Manual Exposure mode is recommended when manual flash mode is chosen. Determine settings such as aperture, shutter speed and ISO speed in accordance with the intent of the shot, and you can adjust the flash output manually based on these conditions.

Step 5: Select a shutter synchronization mode

After selecting the shooting mode, select a flash synchronization mode. Use high-speed sync when the desired shutter speed is higher than the maximum speed the flash is able to synchronize. Consider using first-curtain sync or second-curtain sync for long exposure shots.

On the camera


To set shutter synchronization using the camera, go to [Flash control]→[External flash func. setting]→[Shutter sync.], and select the icon below the flash mode item.


The shutter synchronization modes available are (from left) first-curtain sync, second-curtain sync (also known as “slow-sync flash mode”), and high-speed sync. Select the mode that suits your intent.

How to set shutter sync on the flash unit


Press the “SEL/SET” button and navigate to the flash sync mode icon, indicated in red. Press “SEL/SET” again to display the shutter sync mode options.


Use the Select dial to select the mode. Press the “SEL/SET” button when done.

On the flash unit

Press the “Zoom” button and turn the Select dial to select the focal length. Press the “SEL/SET” button to confirm the selection. If “AUTO” is selected, the optimal flash coverage for the attached lens will be used, and no focal length will be shown next to “Zoom” on the flash display.

*For Speedlite 270EX II, adjustments are made in two phases by manually pulling out the flash head.
