Compact, easy-to-use flash for advanced lighting The guide number of 20 (GN20 ) 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.

Extended warranties are usually very inexpensive and can save you thousands in the future. It's simple and inexpensive to purchase extended warranties and one of the smartest ways to protect your investment.

Electronics can be large, heavy and expensive. You probably don't have the special tools or expertise needed to fix them in a crisis. If you can spare a few thousand dollars without batting an eyelash for new electronics should they break tomorrow, don't buy a warranty. But if you're like most of us, protect yourself by purchasing inexpensive extended warranties when you buy a new product and save yourself big money in the long run.
