  • External Flash for NEX Cameras
  • Guide Number: 20
  • ADI Flash Metering System
  • Built-in Diffuser
  • Expand your creativity with your Alpha 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 Alpha NEX camera for easy and intuitive operation
  • There's also a built-in diffuser which is ideal for wide and telephoto shooting
  • 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 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 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
  • In addition, a switch on the side of the unit offers Indoor and Outdoor settings, 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 System:
  • 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 Alpha 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
