Small, powerful, reliable radio wireless flash This high-output GN28 flash offers the type of optimized performance and control that only a genuine Sony product can provide. It can be controlled directly from the camera and is small enough to fit in a pocket while offering professional durability as well as wireless radio communication for a wide range of applications.

Effective overheating prevention An optimized flash-control algorithm provides excellent flash performance while effectively preventing overheating, for long-term stability and reliability.

Stable radio wireless communication The HVL-F28RM features stable radio wireless communication. One HVL-F28RM that will function as a commander can be mounted on a compatible camera and paired with other off-camera HVL-F28RM units that will function as a receiver. Radio communication provides reliable communication over longer distances than are possible with optical communication, even in bright sunlight or when there are obstacles between the camera and subject. Slow sync, rear-curtain sync, and multi flash are supported .

Multi-flash radio control When used as a flash commander, the HVL-F28RM can control up to 15 flash and/or receiver units in five groups at distances of up to 114 ft (35 m) for extraordinary lighting-control versatility.

Comprehensive control from the camera Flash compensation, light ratio, and other detailed flash parameters can be controlled directly from a compatible camera , and a custom key assignment can allow adjustments to be made while looking through the viewfinder. Flash parameters are shown in the selected camera display language.

Lighting tailored to individual scenes With powerful output that rivals the HVL-F45RM, plenty of light is available for bounce applications, and the flash angle can be set as required via 0-, 20-, 40-, 60-, 80-, and 120-degree click stops. A lock is provided at the 0-degree position to prevent unwanted angle changes in hectic shooting situations.

Metal shoe foot with rugged side frame The Multi Interface Shoe features a newly developed metal shoe foot with rugged side frame, significantly increasing strength and reliability.

Reliable in harsh outdoor conditions Like all of Sony's high-end flash units, the HVL-F28RM features a dust- and moisture-resistant design that contributes to high reliability in harsh outdoor conditions.

Direct light-level control Dedicated + and - LEVEL buttons allow direct, speedy light output and flash-compensation control, and can also be used to control the same parameters on other wirelessly paired flash units for smooth, efficient workflow.

Through-the-lens (TTL) wireless flash Flash output can be accurately determined by through-the-lens light measurement, even when shooting wirelessly. The position and direction of the flash can be adjusted to soften shadows and highlights when shooting a subject from the front, or to add shadows for a sense of depth when needed. Wireless flash-ratio control is available.

High-speed sync (HSS) Normal maximum flash sync speeds mean that the shutter speed must be stopped down when using daylight fill flash, making it difficult to produce background bokeh. High-speed sync allows the flash to be synchronized to the full range of shutter speeds so that large apertures can be used to create bokeh wherever desired.

Test flash mode The test flash mode enables you to check shadows on the subject before taking photos, and also to check the light level using an external flash meter, which is essential for studio photography. The light level of the test flash depends on the light level setting in manual flash (M) mode, and the flash unit fires with a light level of 1/1 in through-the-lens (TTL) mode.

Multi/Micro USB terminal The flash unit can be connected to a computer via its Multi/Micro USB terminal for convenient software updating.

Flash control based on face detection The HVL-F28RM works with the face-detection capabilities of compatible cameras to balance flash output with ambient light conditions so that the subject's face is rendered with lifelike, accurate white balance.

Auto white balance adjustment Color temperature information is transferred from the flash unit to the camera to ensure accurate white balance for natural-looking colors. With compatible cameras flash output is automatically balanced with ambient light conditions so that skin tones are rendered with ideal white balance.

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.
