Sony Alpha HVL-F20S Flash for NEX Cameras

Illuminate your subjects with total control.

The Sony Alpha HVL-F20S 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.

Key Features:

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 NEX-series cameras. This is represented as the guide number (GN) of 20 with a 50mm focal distance.

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.

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.

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 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.

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.
