Sony HVL-F20M Overview

With a notably slim, compact design and ADI / P-TTL support, the HVL-F20M External Flash from Sony is ideal for those looking to add a little fill light to their images or for use as a wireless TTL controller for off-camera flash units without adding too much weight to their gear bag. It offers a modest guide number of 66' at ISO 100 and 50mm along with two coverage settings for 27mm or 50mm with full-frame sensors. Also, the unit can tilt the flashtube upward 75° for achieving softer, more diffuse bounce lighting.
For remote triggering of additional off-camera flash units, the HVL-F20M is able to work as a TTL controller. Also, it has slow, first and second curtain sync settings and will recycle in 0.1 to 5 seconds. Additionally, it runs on 2 AAA batteries and comes with a terminal protector cap and a carrying case.

This unit is compatible with Sony's Multi Interface Shoe and is not natively compatible with the older Sony/Minolta Auto-Lock Accessory Shoe. Though, with the use of ADP-AMA Shoe Adapter, Sony cameras with the Auto-Lock Accessory Shoe can be adapted to use Multi Interface Shoe external flashes with full compatibility.
  • Advance Distance Integration (ADI) flash metering works with cameras and lenses with distance encoders to more accurately balance flash output with ambient light and subject reflectivity by taking camera-to-subject distance into account
  • Effective range of 3.3 to 16.4' when used at ISO 100 and f/2.8
  • Battery life of approximately 90-150 flashes
  • White balance information is automatically transferred to the camera
  • Turn the flash on or off by simply raising or lowering the flash unit
  • Locking foot
  • Flash-ready indicator light

question

How can I set this up as a wireless function for A7?
Asked by: Anonymous
The Sony HVL-F20M can only be used on camera as a controller for a separate off camera flash. It cannot be used as a wireless flash. To use this as a commander, select this setting in the camera flash control menu.

question

Hi, I Have The A7 And The Hvlf20m, When I Press The Shutter On Camera, Flash Fires Two Or Three Times, In All Camera Modes, Can Someone Please Help?
Asked by: Danny
It sounds as if the flash is working correctly. The Sony HVL-F20M External Flash is a fully automatic flash (there is no option to set the flash output manually). Sony's automatic TTL flash system is designed to emit pre-flashes which the camera reads to determine the correct flash output for the actual flash exposure. If the images look correct, then the flash should be operating normally. If your image exposure all look incorrect or over/underexposed, then you may wish to contact Sony to explain your issue and they may require you to send the flash, camera, or both items to them for inspection and/or repair.
