The functionality is somewhat limited (no display, relatively few functions) but all the needed features are there: flash head swiveling and rotating bar, Wide diffuser and reflector card for portraits exist, (P) TTL and Manual can be selected (!) derating can be done in 4 steps, and it automatically zooms to the focal length setting of the lens. Panel is lit funny and catchy labels. Here, everyone finds along well. There is even an operation in slave mode possible and update the firmware via a USB cable. With such a flash - also because of the flash output with the guide number 44 at ISO 100 and maximum telephoto - represents one each camera's internal flash in the shadows.
Who wants to illuminate a wide area with a high quality flash scenarios will be well served with this flash. Who wants to play with more features must loose twice the output in order not to be disappointed.
