This surprisingly compact Sony HVL-F20AM Digital Camera Flash is meant to be a trusty standby for novice photographers who have found the output on their pop-up flashes lacking. The HVL-F20AM essentially doubles the output of most pop-up flashes while not adding any great bulk or hindrance to a camera's operation. The flash has a hinge that allows it to compress downwards on the camera, eliminating the need to fumble with mounting and unmounting a hotshoe flash as it is needed.
Simplicity is further established by the elimination of complex displays and button interfaces. The HVL-F20AM operates with a tug and a twist. Raise the flash from its compressed position to activate it; a simple switch on the side changes the flash from its indoor mode to an outdoor one. Take a picture, then pop the flash back down when finished-it is that easy.
Unique design eliminates the need for an on/off button. Flash is activated by raising the head into shooting position. When not in use, the 1" (24mm) thick flash can sit unobtrusively in the camera's hotshoe.
Two power settings: one suited for indoors, the other outside. When in the inside mode, the flash covers a 27mm angle of view. When set to tele, the flash moves to a 50mm angle of view.
ADI flash metering and automatic white balance compensation with lenses that incorporate a distance encoder.
TTL flash operates with select Sony cameras which provide control over auto-zoom, high-speed sync (HSS), power level switching, wireless flash, bounce flash, modelling flash, and multi-burst functions.
