Sony HVL-F20M External Flash

The Sony HVL-F20M External Flash features a slim, compact design that is only 0.94" thick, but is packed with advanced lighting features for those looking to add fill light to their images or for use as a wireless TTL controller for off-camera flash units. It offers ADI / P-TTL support, 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.
