  • Page 10: Warnings

    Warnings Before using your VS-570F, please read the following safety notices carefully and thoroughly to ensure safe use, and to help prevent damage to your flash or injury to yourself or others. • Do not fire the flash at close range directly into the eyes of people or animals. This can cause damage to the retina and may even lead to blindness.

  • Page 11: Warnings

    Take the product to an authorized service center for repair. • Do not drop or otherwise cause a strong physical impact to the VS-570F, as this could cause a malfunction that may cause it to explode or ignite.

  • Page 12: Installing Batteries

    • Alkaline (1.5 V) Note: For the fastest recycle times and longest battery life, lithium or NiMH batteries are recommended. To install batteries, make sure the VS-570F is turned off and follow these steps: Press on the battery compartment cover and slide it in the direction of the arrow to remove it.

  • Page 13: Mounting The Flash

    Mounting the Flash To mount the flash on your camera, make sure the VS-570F is turned off and follow these steps: Turn the mounting foot lock counterclockwise to loosen it. Slide the mounting foot all the way into your camera’s hot shoe.

  • Page 14: Mounting The Flash

    Mounting the VS-570F on the included stand: You can mount the VS-570F on the included stand in the same way you would mount it on your camera. This allows you to set the flash up on a flat surface or to attach it to a tripod head, light stand, or clamp that has a compatible 1/4"-20 screw mount.

  • Page 15: Turning On The Flash And Firing A Test

    The LCD will display a single OFF indicator, and the Ready light will turn off. To reactivate the VS-570F, simply press any button on the control panel, or tap your camera’s shutter-release button. During long periods of inactivity, it is recommended that you use the power switch to turn the flash off completely.

  • Page 16: Extended Interface

    Extended Interface You can connect your VS-570F to an external power source or PC sync via the extended interface on the side of the flash. External power source: An external power source, such as the Bolt Cyclone Battery Pack, can greatly increase the battery life of your flash and reduce the recycle time in between flashes.

  • Page 17: Using The Automatic Ttl Flash Mode

    Using the Automatic TTL Flash Mode When the VS-570F is mounted on a compatible camera, it can set the appropriate flash level automatically, in conjunction with the camera’s through-the-lens (TTL) metering system. To use the automatic mode, mount the flash on the camera and follow these steps: Each time you turn the flash on, it will be in automatic mode.

  • Page 18: Using Flash Exposure Compensation

    Using the Manual Flash Mode You can also set the VS-570F’s flash output level manually for greater creative control over your images. Seven manual settings are available: 1/1, 1/2, 1/4, 1/8, 1/16, 1/32, and 1/64. The 1/1 setting is the full-power flash, and each successive setting halves the light output.

  • Page 19: Using The Manual Flash Mode

    Press the Mode button repeatedly to cycle through the flash modes until “M” and the flash output level indicator show on the LCD. Press the up or down buttons to set the desired flash output level. The output level will cycle through in both directions. Set the exposure settings you want to use on your camera.

  • Page 20: Controlling Flash Coverage (Zoom)

    Controlling Flash Coverage (Zoom) The VS-570F’s angle of coverage can be adjusted (“zoomed”) to match the focal length of your lens, so that your image is evenly illuminated from edge to edge. When the flash zoom setting is adjusted, the position of the reflectors inside the flash head shift in order to make the angle of coverage wider or narrower.
  • Page 21 When the flash head is angled up or swiveled to the side, the zoom position is set to 50mm. The “50mm” indicator will flash on the LCD, and the zoom can then be manually adjusted (see below). Note: Older cameras that do not offer digital data transmission with the flash do not support the automatic flash zoom control.
  • Page 22 To use the diffuser: Pull the diffuser and reflector panels out of their slot in the flash head. Push the reflector back in, and let the diffuser lay flat against the flash lens. The diffuser also softens the light, providing an alternative when no surface is available for bouncing the flash (see Bouncing Your Flash on page 23).

  • Page 23: Bouncing Your Flash

    The light will bounce off of the larger surface before striking your subject to provide softer, more natural illumination. The VS-570F flash head can be tilted up at 45°, 60°, 75°, and 90° angles to the lens.

  • Page 24: Bouncing Your Flash

    Tip: Bouncing your flash off of colored surfaces can create a color cast in your images. Bouncing off of a white or neutral-colored surface will not alter the color of the light, while bouncing off of a gold-toned surface can give portraits a warmer look.

  • Page 25: Using Rear- Or Second-Curtain Synchronization

    The VS-570F supports rear-curtain sync modes on cameras that offer the setting. Consult your camera’s manual to find out how to activate it. Use your camera’s manual or shutter-priority mode to control the amount of blurring and light trails you capture by varying the shutter speed.

  • Page 26: Using The Vs-570F As A Wireless Ttl Slave

    Using the VS-570F as a Wireless TTL Slave You can set the VS-570F as a wireless TTL slave for both the Nikon and Canon TTL systems. This enables you to use a Nikon or Canon wireless TTL master to control the VS-570F as a slave flash unit.

  • Page 27: Using The Vs-570F As A Wireless Ttl Slave

    If desired, adjust the flash coverage angle by pressing the Zoom button repeatedly. Make sure that the red light on the front of the VS-570F is blinking. This indicates that the unit is ready to fire in wireless TTL slave mode.

  • Page 28: Using Your Vs-570F As A Wireless Manual Flash

    This works optically—when the VS-570F “sees” another flash firing, it will instantaneously fire along with it. Setting the remote flash units manually: To set a VS-570F flash unit to function as a slave with the output level selected manually, follow these steps: In Manual mode, use the up and down buttons to select the power output (1 through 1/64).

  • Page 29: Using Your Vs-570F As A Wireless Manual Flash

    If the slave flash is not set correctly, it may be triggered by the pre-flash and fire before the camera’s shutter opens. In order to ensure that the VS-570F fires at the correct time, there are three different slave modes available: modes 0, 1, and 2.

  • Page 30: Positioning Remote Flash Units

    Positioning Remote Flash Units You can create a professional lighting setup by positioning remote units singly or in groups to function as main, fill, accent, and other lights. Metering your scene with a handheld light meter and setting your light ratios to achieve specific looks will give you a professional level of creative control.

  • Page 31: Upgrading The Firmware On The Vs-570F

    • The wireless sensors are located on the front of the VS-570F. Make sure that sensor is facing the master flash and that there is no obstruction between the two units. • When photographing outdoors or in bright ambient light, the sensors can be overwhelmed by ambient light, which will lower their sensitivity.
