Key FeaturesHigh-power illuminationHigh-power illumination (guide number: 43)New LED video lightWith the new built-in LED video light it has never been easier to switch between stills and movie shooting even in low-light conditions. LED enables checking and setting the light and shadow conditions before shooting still image or moviewith live view function of EVF equipped camera. Maximum luminance of 400 lux/(0.5m), with illuminating distance ofapproximately 3-1/4 feet (1m) at ISO3200/F5.6.Longer effective rangeLonger effective range of over 30 ft. (10.5m)“Quick Shift Bounce”The innovative “Quick Shift Bounce” system allows the HVL-F43M to orbit 90 degrees left and right, allowing you to maintainhorizontal light distribution even when shooting vertically. In addition to pivoting side-to-side, the flash unit can also tiltdown 8 degrees or back 150 degrees, ensuring customers the lighting freedom they need to capture that perfect shot.Versatile bounce anglesVersatile bounce angles: 90° up, 90° left. This allows the flash head to be rotated while maintaining the set bounce angle,so you can quickly switch between horizontal and vertical format without changing the light angle.Built-In Bounce sheetThe built-in bounce sheet can be used even when shooting in a vertical position without changing the angle of reflectedlight.Auto white balanceAuto white balance (signals color temp. to camera)Auto zoomAuto zoom optimized for camera sensor sizeDust and Moisture resistant designSealing materials are set at joints of outer materials (body, LCD panel, Mounting Foot etc.) and around movement/operating parts thereby increasing the life of your flash unit.Modeling light capabilityModeling light capability allows the HVL-F43M to pulse, helping photographers determine where shadows will fall beforetaking the picture, so they can alter lighting or subject positioning as necessary.Retractable wide-angle panelRetractable wide-angle panel (15mm angle)Wireless Ratio ControlWireless Ratio Control allows customers to wirelessly control up to three groups of flashes, as well as specify the luminosityratio for each group, so they can enjoy multiple-flash lighting techniques without the need for special equipment ortedious exposure settings.Simple controlsSimple controls, test button, power saving modeTTL meteringHVL-F43M External Flash/Video LightThe Sony® HVL-F43M flash unit delivers flexible lighting control forphotographers. The innovative “Quick Shift Bounce” system allows the flash topivot 90 degrees left and right, and Wireless Ratio Control allows the wirelesscontrol of up to three groups of flashes with user-selected luminosity ratios.
