Since the Samsung NX 10/11 with lens 18-200 mm for the length of the lens of the built-in flash at the wide angle is not usable, because it leads to strong vignetting at the bottom, I bought the compact flash SEF20A. A right decision, because the flash is really compact. It slips easily into your jacket or pants pocket carry, because even the hot shoe is folded away (awesome). Otherwise the lightning meets all expectations; solid quality workmanship and absolutely faultless function. Bltzstärke is also fast manually adjustable as needed and the flash angle can be adjusted vertically up to 90 degrees for bounce flash.
