Samsung ED-SEF220A External Flash

The ED-SEF220A External Flash from Samsung is designed to work on the hot shoe mount of the Samsung NX and EX series of cameras. The flash is compact, lightweight and provides automatic TTL exposure control. For its compact size this is a very powerful flash with a Guide Number of 16m (52.5') in the Wide Mode and 22m (72') in the Tele Mode, but the A-TTL allows for subtle low light flash and fill-flash photography as well.
