Bring indoor shots to life
Give your flash photography a major boost with the Sony HVL-F20S. This powerful-yet-compact add-on flash lets you shoot in low-light conditions from up to twice the distance of your camera's included flash. It works easily and automatically with your Sony camera to deliver precise illumination that can reveal stunning detail and add drama to your images. Plus, you get the added ability to direct light where you need it for more professional-looking photos.

The right light for a better look
The HVL-F20S's flash head can be aimed to create different lighting effects. Turn to the "indoor" setting when you want to bounce the flash off the ceiling for softer illumination with less glare and fewer shadows — ideal for more pleasing portraits. Use the "outdoor" setting to fire the flash forward and aim the most light possible at your subject.

Product Highlights:

  • compatible with Sony NEX series digital cameras
  • "indoor" setting for bounce flash and "outdoor" setting for forward-firing flash
  • built-in diffuser for wide and telephoto scenes
  • TTL (through-the-lens) exposure works automatically with Sony cameras for proper flash output

  • 2-3/8"W x 1-5/8"H x 2-5/8"D
  • weight: 2.3 oz.

Crutchfield Customer Review (What's this?)

Functioned as expected and a lot better than the small kit flash. Better coverage in flash capability with a tele/wide. Recommended for any one wishing to improve their Sony 5 and the like, Cameras.



Excellent bounce flash

Crutchfield Customer Review (What's this?)

This flash made a huge improvement in my photos. It works best in 'bounce' mode, where the flash bounces off a ceiling, resulting in softly diffused light resulting in far better pictures of people compared to using direct flash. It's powerful enough for most indoor situations, and is far more compact than most DSLR flashes. I also like how it does not have internal batteries. It does drain the NEX camera battery faster, but I carry an extra camera battery around anyways.

Pros: Great bounce flash photos No batteries (uses camera power) Compact in size

Cons: Does not fit both of my NEX bodies (fits on my NEX-5N, but not NEX-6) Flash power adjustments sometimes needed to avoid overexposed photos

Product Research


Overview: The Sony HVL-F20S flash is designed for use exclusively with Sony cameras with the Smart Accessory Terminal. The flash is powered by the camera's battery, so there is no need for a separate flash battery. The flash turns on and off by raising and lowering the flashtube.

Compatibility: The HVL-F20S is compatible with Sony α NEX-series cameras, including the NEX-3, NEX-5, and NEX-C3.

Bounce Switch: The left end of the flash tube can be turned clockwise to the Bounce position the flash light is set at 75° upward so it can bounce off of a ceiling or wall to soften shadows. If the switch is turned counter-clockwise to the Direct position, the flash is aimed directly at the subject (0°).

Tele Switch: The right end of the flash tube can be turned counter-clockwise to the Tele position to extend the flash beyond its normal range. This is helpful in outdoor shooting when the subject is too far from the camera to be reached by normal flash. Flash range in standard position is equivalent to 16mm focal length range (35mm equivalent: 24mm), while the range in the tele position is equivalent to 35mm (35mm equivalent: 50mm). The Tele switch is only enabled when the Bounce switch is in the Direct position.

Wide Panel: Included with the HVL-F20S is a wide panel light diffuser, which attaches over the lens of the flash. The wide panel is especially effective when used with the separately purchased Ultra Wide Converter, which is equivalent to 12mm focal length range (35mm equivalent: 18mm).
