A DIN A4 Operating instructions in German was in addition to the original pattern in English and Chinese also included.
A diffuser was also supplied, this part is, let's say, is a nice little bonus no longer.
Who has ever worked with the Canon flash can be found with the YN568 quickly master.
The quality of the flash is okay, but compared to the Canon lacks the seal at the bottom and the flash itself can be swiveled without that like the Canon the lock must first be solved, this is in my view is not a problem.
All in all, the processing of the Canon better, although this does not mean that the YN is poorly processed, personally I am with the quality of workmanship Considering the price more than satisfied.
The flash works on my Canon 1DsIII far without restrictions, however, all the functions have not been tested to the smallest detail.
The ETTL functionality is given, which was a decisive factor for me.
The interplay between Master / Slave with the 580EXII turned easily is as a first test showed. Both the Canon and the YN can act as a master.
In summary, according to 1-day trial, I note the following
I would buy it again. Who has to decide to buy a flash I would recommend the YN definitely be taken into consideration.
