The diffuser is small, lightweight and fits perfectly on the Speedlite 580 EX II it can remain for transport on the flash unit and simultaneously protects the sensitive Frontscheibe.Beim putting attention to the small bulge on the eighth one longitudinal side. they must face upwards. Your correspondence can be found on the housing of the 580 EX II. Only then can the diffuser completely defer. The mentioned in other reviews difficulty setting up I can not nachvollziehen.Er sits fortunately fit. Otherwise, the light plastic part could drop quickly and are lost. For best results when recording, I achieved when I placed the reflector on 45 degree. Uniform illumination, even with a short focal length and reduce the shadow. The disappearance of any shadow, can seriously expect anyone; I myself would not want that too, because otherwise any depth is lost. Noteworthy: The diffuser causes a slight shift in the color "yellow" direction. Negligible in my eyes who it takes exactly, should pay attention. Overall, for little money a useful accessory.
