About Sony HVL-F20M

Flash and lights


Compact, easy-to-use flash for advanced lighting

The guide number of 20 (GN201) makes it powerful enough to illuminate subjects up to 16.4 feet away (TELE position, ISO 100, F4).

Bounce flash

As the name implies, "bounce flash" means that light is bounced off a surface such as the ceiling rather than being directed straight at the subject. This reduces the intensity of shadows and produces a softer light for more natural-looking images. Since the flash position can be easily adjusted via a slide switch, this bounce flash technique can be used anytime, anywhere.

Direct flash

Simply use it facing forward as a direct flash that provides greater reach than the camera's built-in flash. Whenever you need it, just attach it and count on its ability to bring out the details in evening outdoor situations as well as indoor in dimly lit rooms.

Automatic power on / off

The flash unit automatically powers on when it is raised into a shooting position, and turns off when the flash body is lowered flat. This means that the flash is ready when you're ready to shoot, and also helps to avoid unnecessary power drain while not in use.

Wireless control

Attach to a compatible camera and use this flash unit to wirelessly control other compatible flash units.

Compact and slim

The HVL-F20M is only 0.94" 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.

Advanced Distance Integration (ADI)

ADI provides automatic metering that is virtually unaffected by the reflectance of subjects or backgrounds, maintaining correct exposure even with overly reflective or overly dark subjects. It pre-flashes the unit to incorporate the reflected light measurement, together with precise distance information from a compatible camera's lens, to achieve the optimum flash level (E-mount not supported).

Auto White Balance Adjustment

Color temperature varies according to the environment you're shooting in, and the color temperature of a flash should match that of the ambient light to look natural. With this intelligent function, color temperature information is transferred from the flash unit to the camera for correct White Balance setting, thereby enabling more natural-looking flash photography.

Multi Interface Shoe

This product is designed for use with Multi Interface Shoe flash.

Expand your creativity with your Alpha NEX-6 interchangeable lens camera or Alpha a58K DSLR camera and the HVL-F20M external flash. This compact and lightweight flash extends the illumination range beyond the camera's built-in flash and includes Sony's multi-interface shoe for expanded compatibility. 

Bounce flash enables shadowless indirect lighting while TTL (through the lens) flash exposure is automatically controlled by your 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-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. 

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. 

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 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 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
