Sony HVLF20M Multi-Interface Shoe External Flash

Sony HVLF20M Multi-Interface Shoe External Flash

The Sony Multi Interface Shoe External Flash is compact and slim with a body that’s only 0.94-inch thick, but packed with advanced lighting features. Its guide number of 20 (GN202) makes it about two or three times brighter than a built-in flash. Powerful enough to illuminate subjects up to 16.4 feet away (TELE position, ISO 100, F4), it will expand your shooting possibilities.

Extends Flash Range

Though 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 

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

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-inch 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-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 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 α 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. 

Compact and Slim

The HVL-F20M is only 0.94-inch thick, giving it an extremely slim profile that makes it easy to use and to carry. Its compact body takes up minimal space in your camera case or bag where room is limited, and once you put it on your camera it's very easy to handle.
