About Sony HVL-F20S

Expand your creativity with your a NEX interchangeable lens camera and the HVL-F20S external flash. This external flash extends the illumination range beyond the camera's included flash. Bounce flash enables shadowless indirect lighting while TTL (through the lens) flash exposure is automatically controlled by your a NEX camera for easy and intuitive operation. There's also a built-in diffuser which is ideal for wide and telephoto shooting.

Sony HVL-F20S Features

  • Extends flash range beyond camera's included flash: Though compact and lightweight, the HVL-F20S has a maximum range twice that of the included flash units of the NEX-3, NEX-5 and NEX-C3 cameras. This is represented as the guide number (GN) of 20 with a 50mm focal distance
  • Bounce flash enables shadowless indirect lighting: When set to 'indoor' shooting mode, the flash points up to bounce light off the ceiling for shadowless illumination of your subject. When set to the 'outdoor' shooting mode, the flash directs light directly at your subject
  • Built-in diffuser for wide and telephoto shooting: With the built-in diffuser, the flash illumination covers a wider angle of view or if users want to shoot at a greater distance, they can rotate the dial on the side of the flash unit to the 'Tele' Position
  • Easy intuitive operation: Unlike most external flash units, the HVL-F20S has no dedicated ON/OFF switch. Instead, power is automatically switched on simply by raising the flash unit into the shooting position
  • ADI Flash Metering System: The ADI (Advanced Distance Integration) flash metering system offers the optimum flash metering and automatic white-balance compensation regardless of the background conditions or the subject's reflectance

Great Improvent


from PA  -  Casual Photographer

This flash is a significant improvement over the original flash that comes with the NEX cameras. The range is better and plus the bounce feature makes it possible to create a much nicer effect. The only drawback is that you are not supposed to leave it on the camera when it is in the bag. It is dramatically bigger than the original flash but it is well worth it!

Great...until it stopped working


from Livonia, MI

The Flash decided to stop working in the middle of my sons first birthday party. Sad to say that until today I had nothing but positive things to say about the NEX series.


Questions & Answers Powered by TurnTo®

Questions about this item:

Shopper  I just purchased NEX-C3 and was searching for Flash. Is this only accessory I can use with NEX-C3 or there any alternatives?
BOBBY E  I am unaware of any flash other than the HVL-504. The flash works very well in the diffusion mode as a fill light for outdoor candids of people working with hats and shades. My photos can't really be called candids because I ask my subjects to remove the sunglasses. It is really bright in westen Colorado. I have experimented with two additional strobes attached to an "L" bracket.The strobes are triggered by the Sony flash. I need to do more testing as the arrangement blows everything out. We have plenty of power,just need to learn to use this powerful combo.
Shopper  will this flash eliminate the shadow that is created when using a telezoom lens? (18-200)
JAVIER P  Yes it does!
Shopper  Do you using this flash can solve "shadow" effect when we are using the lens of 50-200mm? Thanks
MICHAEL M  The answer is yes...i purchased the item for that very reason. I actually have 3 different lenses for this awesome camera and the flash covers each lens. M. Moore
