Product Overview
The Godox V1S is a TTL Li-ion Round Head Camera Flash designed for SONY cameras. It is fully compatible with SONY TTL systems and can function as either a Transmitter (TX) or a Receiver (RX) unit within a wireless flash group.
Transmitter and Receiver Units
When the V1S is attached to the camera, it acts as the "Transmitter" unit. Other V1S units controlled wirelessly are designated as "Receiver" units.
The flash can also be wirelessly controlled by other compatible transmitters such as the X1T-S or XProS (sold separately). For detailed transmitter functions, refer to the respective transmitter's instructions.
Utilizing the 2.4G radio transmission wireless shooting function allows for advanced wireless multiple flash lighting, mirroring the ease of TTL autoflash shooting.
Power Management
Use the ON/OFF Power Switch to power the flash unit on or off. It is recommended to turn the unit off if it will not be used for an extended period.
- Transmitter Mode: The flash unit will automatically turn off after approximately 90 seconds of idle use. Pressing the camera shutter halfway or any flash button will wake the unit up.
- Receiver Mode: The unit will enter sleep mode after a period of idle use (default is 60 minutes, adjustable). Pressing any flash button will wake it up.
Custom Functions (C.Fn):
- Disabling the Auto Power Off function is recommended when the flash is used off-camera (refer to C.Fn-STBY settings).
- The Receiver Auto Power Off Timer is set to 60 minutes by default, with a 30-minute option available (refer to C.Fn-RX STBY settings).
Wireless Shooting Functions
The V1S enables advanced wireless flash photography, allowing for TTL autoflash shooting with multiple flash units.
Positioning and Operation Range
A diagram illustrates the basic relative position and operation range for wireless flash shooting. It shows a transmitter unit mounted on a camera and a receiver unit positioned remotely using a supplied mini stand. The transmission distance is indicated as about 100 meters.
Key Points:
- Transmission distance is approximately 100m.
- Use the supplied mini stand to position the Receiver unit.
- Perform a test flash and test shooting before critical use.
- Transmission distance may be reduced by factors such as Receiver unit positioning, surrounding environment, and weather conditions.
Wireless Multiple Flash Shooting
Receiver units can be divided into two or three groups (e.g., A, B, C) to perform TTL autoflash with adjustable flash ratios. Different flash modes can be set for each group, supporting up to 4 groups.
Diagrams show configurations for Auto Shooting with Two Receiver Groups (A, B) and Auto Shooting with Three Receiver Groups (A, B, C).
Using Automatic Wireless Flash with a Single Receiver Unit
- Transmitter Unit Setup: Attach a V1S camera flash to the camera and set it as the Transmitter unit. Groups (M/A/B/C) can be set to TTL separately.
- Receiver Unit Setup: Set another V1S flash as the wireless Receiver Unit.
- Communication Channel Check: Ensure the Transmitter unit and Receiver unit(s) are set to the same communication channel. If not, adjust them accordingly.
- Wireless ID Settings: To prevent interference, change the wireless channels and wireless IDs. Triggering is only possible when the wireless IDs and channels match between the Transmitter and Receiver units. Access this via the MENU button, then C.Fn ID. Select OFF for channel expansion shutdown and choose a figure from 01 to 99.
- Setting the Communication Channel: If other wireless flash systems are nearby, change the channel IDs to prevent signal interference. The channel IDs must be identical for the Transmitter and Receiver units.
- Flash Operation Check: Press the Transmitter unit's Test Button ▶. The Receiver unit should fire. If it does not, adjust the Receiver unit's angle towards the Transmitter unit and its distance from the Transmitter unit.
Confirm that the Transmitter flash ready indicator is lit.
Using Automatic Wireless Flash with Multiple Receiver Units
To achieve stronger flash output or more convenient lighting control, multiple Receiver units can be used. Follow the same setup steps as for a single Receiver unit.
Any flash group (A/B/C/D/E) can be configured. When multiple Receiver units are active and the Transmitter unit is firing, automatic control ensures all groups fire with consistent flash output, meeting standard exposure requirements.
If the Receiver unit's auto power off function is active, pressing the Transmitter unit's test button will power it on. Note that test firing is unavailable during the camera's regular metering time.
The effective time of Receiver auto power off is adjustable (C.Fn-RX STBY).
Using Fully Automatic Wireless Flash
Settings like Flash Exposure Compensation (FEC) made on the Transmitter unit are automatically applied to the Receiver unit, requiring no separate operation on the Receiver.
Use the following settings for wireless flashes, mirroring methods used for normal flash shooting.
Flash Exposure Compensation (FEC) [? See Page 39]
Transmitter Unit (Multiple Units)
Multiple Transmitter units can be used. By preparing several cameras equipped with Transmitter units, users can switch between cameras during shooting while maintaining the same lighting setup with the Receiver unit(s).
Troubleshooting Guide
Refer to this guide if you encounter issues with the flash unit.
The Camera Flash does not fire.
- Issue: Flash not securely attached. Solution: Attach the camera's mounting foot securely.
- Issue: Dirty electrical contacts. Solution: Clean the contacts on both the flash and camera.
- Issue: Flash ready indicator (✔️ or ❌) not displayed in viewfinder. Solution: Wait for the flash to fully recycle and the ready indicator to light up. If it lights up but isn't shown in the viewfinder, ensure the flash is securely attached to the camera hotshoe.
- Issue: Flash ready indicator does not light up. Solution: Check battery power. If low, a blinking ⚡ symbol will appear on the LCD panel. Replace the battery immediately.
The power turns off by itself.
- Transmitter: Auto power off activated after 90 seconds of idle operation. Press the shutter button halfway or any flash button to wake up.
- Receiver: Unit enters sleep mode after 60 minutes (or 30 minutes) of idle operation. Press any flash button to wake up.
Auto zoom does not work.
- Issue: Flash not securely attached. Solution: Attach the camera flash's mounting foot securely to the camera.
The flash exposure is underexposed or overexposed.
- Cause: High-speed sync used. Note: High-speed sync reduces the effective flash range. Ensure the subject is within the displayed effective flash range.
- Cause: Manual Flash mode used. Solution: Set the flash mode to ETTL or adjust the flash output.
Photos have dark corners or only parts of the target subject are illuminated.
- Cause: Lens focal length exceeds flash coverage. Solution: Check the set flash coverage. This unit provides coverage between 28mm and 105mm, suitable for medium-format cameras.
