Our take on the Samsung SEF20A

by Tara W.

Get better-looking flash photos with your Samsung NX Series camera. The SEF20A 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.

Overview: The Samsung SEF20A external flash unit is designed for use with the Samsung NX-series and the TL500 digital cameras.

Power Requirements: The SEF20A is powered by 2 "AA" alkaline or Nickel-Metal Hydride (Ni-MH) rechargeable batteries. With "AA" alkaline batteries, you can get approximately 120 flashes, and the recycling time is approximately 6-60 seconds between flashes. If "AA" Ni-MH batteries are used, you can get approximately 200 flashes with a 5-60 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.

EV Adjust: You can adjust the amount of flash light from -1.0 EV to +1.0 EV in 1/3 EV increments. The intensity can be adjusted using the EV Adjust button on the back panel of the flash. A row of LEDs will indicate the selected amount of flash in 1/3 EV increments.

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.

Dimensions: Width: 2.518", Height: 1.753" (at 0°), Depth: 3.518", Weight: 4.29 ounces
