Our take on the Samsung SEF42A

Enjoy flexible lighting options when you add this powerful flash to your Samsung NX Series camera. It lets you shoot in low-light conditions from greater distances than your camera's built-in flash will allow. Plus, you can tilt the flash head to direct light where you need it for more professional-looking results. Reflected light provides softer illumination with less glare and fewer shadows when you bounce it off walls or ceilings — ideal for taking pleasing portraits. The flash mounts to your camera's accessory shoe.

Hands-on research

Product Research


Overview: The Samsung SEF42A external flash unit is designed for use with the Samsung NX-series and the TL500 digital cameras. It has a large LCD panel on the back to allow you to check the status of the flash, and set the flash functions.

Flash Modes: The flash supports the A-TTL (Advanced Through-the-Lens) flash mode when used with a compatible Samsung camera. The light entering through the lens is measured and an appropriate level of exposure is calculated, basing the exposure and shutter speed set to the camera in the A-TTL mode.

Power Requirements: The SEF42A is powered by 4 "AA" alkaline or Nickel-Metal Hydride (Ni-MH) rechargeable batteries. With "AA" alkaline batteries, you can get approximately 220 flashes, and the recycling time is approximately 8-60 seconds between flashes. If "AA" Ni-MH batteries are used, you can get approximately 280 flashes with a 6-60 second recycling time.

Flash Angles: If you wish to use bounced flash, you can adjust the angle of the flash unit vertically to 45°, 60°, 75°, and 90°. Bounced flash creates less shadow than direct flash, and the light is more uniformly distributed to the subject.

Flash Adjust: You can adjust the amount of flash light that is emitted when the flash is in the manual mode. The LCD panel will indicate the selected amount of flash as a PR value: 1/1, 1/2, 1/4, 1/8, 1/16, or 1/32.

Zoom: The SEF42A has a built-in power zoom head, which can be controlled through the camera, to automatically set an appropriate range of flash light according to the focal distance of the zoom lens in use. You can either set the focal distance automatically in a range of 28-105mm, or manually, using the zoom button on the flash, to a focal distance of 28, 35, 50, 80, or 105mm. The focal distance appears in the LCD panel.

Flash Stand: When not using the flash, you can store it on the included stand. The flash unit is supported by its hot-shoe connection on the stand.
