Possession of a FZ1000 where I finally wanted to treat an external flash for the purpose of better shooting in the dark. Previously owned a FZ150 and the jump on the FZ1000 was clearly what the image quality concerns in the dark but a lot of fun making it now with this flash unit! That leaves my room like daylight illuminate where I've photographed. Between the built-in flash and this are worlds apart. Very cool and bounce flash is due to the swiveling head where you can create really great effects .. depending on the subject, it looks much better than flashed directly. Can I recommend everyone! That was a very worthwhile investment, and I did not at all what I failed to advance without flash)
