Interestingly Blitz - But you have to know what you want to do

Equally ahead, I do not have this flash (yet).
But would here like to comment on what you need to consider my opinion.
Especially because I realize that even beginners flirting with this flash.
(This is not a criticism, but only an aid)

The flash it seems to give in various trim levels, including with the remote controls.
To this end, I would like to say (after what I can see pictured here) that the flash only as E-TTL flash
works when it is mounted directly on the camera shoe. Ie it can be a 100% replacement of the term E-TTL
Data take place (between the camera and flash).

The radio trigger parts show no noisy image E-TTL contacts (You only see a silver contact in the middle).
Will hot, transfer them either via radio, even when looping through E-TTL signals - send only to the flash
a signal that he should trigger, but not (matched with the camera) and at what intensity. This one should know
you should keep for example a trigger in his hand, mount the receiver on the camera shoe and it still flash.
The flash will presumably trigger, but no, he TTL data from the camera receives. It is then,
the settings manually make the flash.

The same applies if a transmitter is mounted on the camera and the flash on the camera does not, but somewhere
is and it is mounted on the radio receiver (keyword: Unleashes flashes). The flash will indeed trigger,
but equally without TTL control, as the transmitter will not transmit TTL signals). He must be set manually.

Those who want to remotely trigger the camera while the E-TTL want to use the flash function, should
the flash mounted directly on the camera. The receiver then in this case is not "underneath" mount,
but otherwise attach in anywhere near the camera, since a cable from the receiver to the camera
must be performed.
As a side note it should be said, the assembly shown in the image on the camera's hot shoe is actually just as meaningful
Mounting possibility of the receiver on the camera (if you installed any external flash - otherwise enters the one as described above).

Those who like the full TTL functionality (unleashed) wants to use, has to look also for other stations / Emfängern,
which transmit these signals. Here you will also find that these parts have as many contacts as the original shoe
of the camera.

..I weiss..vielleicht little too much, but hopefully understandable written ....
..auch I do like to disabuse because I do not have the flash and only for the images and data shown here
have argued .....
