There are not many compact flash units for the A6000. This Sony flash unit fits perfectly with the camera and in the mounted state little disturbing because it is simply folded in pos. Off. Further still function as a "detonator" for External Blitzer remains important to allow expansion by strong flash units. A light adjustment as a fill is easily possible in the Camera menu. All in all a good very practical and small to verstauendes device that can be always with you.
