The flash is super Powerful and light. I use it with a Sony Alpha 77II Previously had a Metz flash 44 was considerably weaker. The flash adapter is new and in my opinion not as robust as the old. With frequent use, it is lightning sometime overheated and no longer flashes. For a device of this price range really not ok. The adjustment of flash orientation is really good. Because of the overheating problem I have in the Internet researched probably a firmware update available that can be however carried out by a specialist workshop. If I did that I will report if my problem is solved. Greeting Good luck for!
