I purchased the flash unit for my Sony RX 100 II and am as far as the recommendation of the already-reviewed by me book by Martin Vieten for Sony RX 100 II & RX 100 followed. The handling of the flash unit is easy to understand even for the novice. I've used the device at several portraits in Scene Mode Portrait. The instrument can be so eingsetzt that the flash is aimed directly at the object. Preferable is the setting "Bounce", with which the flash can be directed towards the ceiling, so that the object is illuminated indirectly. I have made several comparison shots with the board and the flash HVL F 20 M and am excited about the Super illumination when using the HVL F 20 M. The jump in quality is enormous. Especially when shooting at family gatherings and wherever it comes to people who Bltz will now be used with me. Because he is so nice and light, he will be always with you on holiday in city tours. However, I recommend a price comparison on the Internet. 189 seem too expensive by far.
