Very good flash, but something irritating manual

In order to assess my review first: I am ambitious amateur photographer, but with flashing so far little experience.
I purchased the flash for use on my NEX-6 and am very happy with it after the first test shots. In particular, the degree of adjustment for the alignment of the flash open up a lot of opportunities. By adjusting to the side combined with a flip up the flash head can for example also take place just bounce to the ceiling against a room wall.

For handling, I must say that the flash of the weight and the size was just allows a good handling on the small NEX. Even heavier and larger would be very used to.

Somewhat confusingly, I found the manual. In my view, this suggests by its somewhat vague expression that off-camera flash with the internal flash of NEX as a master and the F43M would work as a slave. This is not so, at least I did not get it to follow instructions.
