Sony HVL-F20S Specification Guide
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
The 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.
