More details on the Sony HVL-F28RM
Overview: The Sony HVL-F28RM is a wireless compact flash unit for Sony α-series (Alpha Series) Interchangeable-Lens Cameras. It supports 2.4GHz wireless multi-flash photography as a commander or receiver unit. The head tilts forward and backward, supporting both direct and bounce flash. The flash comes with a mini-stand, and a cloth storage pouch. It is powered by two AA-size alkaline or Nickel-Metal Hydride (NiMH) batteries (not included).
Compatibility: The HVL-F28RM electronic flash is designed for use with Sony α-series digital cameras equipped with the Multi-Interface Shoe. This includes those with the E-mount (mirrorless) and A-mount (DSLR). It also works with Sony Digital Still Cameras (with non-removable lenses) and Vlog Cameras that are equipped with the Multi-Interface Shoe. With many of the compatible cameras, you can control flash compensation, light ratio, and other detailed flash parameters from the camera.
Bounce Flash: The HVL-F28RM's flash head can be tilted (up/down) from 0° to 120° to illuminate your subject with reflected light instead of direct light. (The head does not swivel from side-to-side.) Reflected light reduces the intensity of the shadows, and produces a softer light on the subject. There are stop positions at 0°, 20°, 40°, 60°, 80°, and 120°. You should consider the flash range, focal length of the lens, and distance to the reflective surface, when determining the bounce angle.
Wide Panel: The HVL-F28RM has a built-in wide panel that can be pulled out when needed to cover focal lengths from 24mm to 50mm. This prevents having darker areas on the periphery of the photos because of the difference in light intensity. The wide panel is stored in the area above the flash tube when not in use.
Bounce Sheet: The built-in bounce sheet creates a highlight in the subject's eyes, making the subject look more vibrant. The bounce sheet pulls out when you pull out the wide panel. You can then push back the wide panel to use the bounce sheet. The bounce angle should be set to 80° upwards. The bounce sheet is helpful when shooting portraits.
Flash Compensation: When using a flash mode that supports TTL (through-the-lens) metering, the flash intensity is automatically adjusted. You can correct the automatically adjusted flash using Flash Compensation. You can set the Flash Compensation values between -3.0 and +3.0 in steps of 0.5 or 0.3 EV.
Flash Power Level: During Manual Flash mode, you can specify the flash power level from 1/1 (brightest) to 1/128 (darkest). The interval of the steps can be set to 0.3EV or 0.5EV.
Multiple Flash: In Manual mode, you can set the unit to flash multiple times while the shutter is open. Multiple flash allows motion of the subject to be captured in a single photograph for later analysis. You will need to set the flash frequency (1 to 100 Hz), the number of flashes (2 to 100), and power level (1/8, 1/16, 1/32, 1/64, or 1/128).
High-speed Sync: High-speed Sync (HSS) eliminates the restrictions of flash sync speed and enables the flash to be used throughout the entire shutter speed range of the camera. This allows you to shoot with a wide aperture, leaving the background out of focus, and accentuating the front subject. The HSS feature can be turned on or off in the camera menu.
Auto White Balance: White balance is automatically adjusted on the camera, based on the color temperature information at the time of the flash firing. The camera should be set to Auto White Balance or Flash White Balance, while the flash unit should be attached to the unit and in the TTL flash mode.
Wireless Operation: The HVL-F28RM can be used for radio wireless flash photography when used with another flash unit that supports radio wireless communications. The flash unit is in commander mode when the power switch is in the ON position. To configure the flash unit as a receiver unit, you should set the power switch to "A," "B," or "C." The Pairing button lets you pair the flash unit with other flash units or a wireless commander unit. You can pair the flash with up to 15 receiver units in up to 5 groups at distances of up to 114 feet.
Test Flash: The Test button illuminates amber when the flash is charged and ready to fire. You can try a test-flash before shooting to check the light level or check shadows.
Power Requirements: The HVL-F28RM is powered by two Alkaline or Ni-MH "AA" rechargeable batteries (not supplied). Fresh alkaline batteries provide enough power for more than 110 flashes. Fully-charged Ni-MH batteries (2100mAh) can power approximately 130 flashes or more. The Test button flashes slowly when the batteries are running out of power, and flashes quickly when the flash unit is no longer capable of firing.
Overheat Protection: The flash has Overheat Protection that suspends operation until the temperature of the unit falls back to normal. When overheating is detected, the Test button will flash in red. You should turn off the flash unit for approximately 20 minutes to allow the unit to cool down.
