Extends flash range beyond camera’s included flashThough compact and lightweight, the HVL-F20M has a maximum range twice that of the included flash units of the NEX-6 or SLT-A58K and includes Sony's new Multi Interface shoe for expanded compatibility. This is represented as the guide number (GN) of 20 with a 50mm focal distance.
Bounce flash enables shadowless indirect lightingWhen 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 shootingWith the built-in diffuser, the flash illumination covers a wider angle of view or if users want to to shoot at a greater distance, they can rotate the dial on the side of the flash unit to the ‘Tele’ Position. While the 'Tele" setting reduces the width of flash coverage, it extends the range to illuminate more distant subjects.
Easy intuitive operationUnlike most external flash units, the HVL-F20M has no dedicated ON/OFF switch. Instead, power is automatically switched on simply by raising the flash unit into the shooting position. In addition, a switch on the side of the unit quickly moves the flash from direct to bounce, making it easy to obtain flash illumination that suits the shooting situation. A charging lamp indicates when the flash is ready to fire.
ADI Flash Metering SystemThe 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. ADI flash metering works in combination with ? cameras and lenses that incorporate a distance encoder. When used with these lenses, the camera calculates a guide number to control TTL (through the lens) flash metering. This guide number is calculated according to distance from the subject, ambient light and pre-flash reflectivity of the subject and the background.
