Looking on the internet I came across the provider Yongnuo - and what surprised me was the consistently good reviews. Price and performance gave rise to impatience, to order the device. Only a little disappointed I was not to have noticed when ordering that despite my "caution" I had not noticed that we have chosen a supplier who supplies from China. Instead announced up to 5 weeks, the unit came after 3 weeks and without fearing inch inconvenience (but for how today usual with "Trick 17" ....).
I use the flash on my EOS60D: The first impressions are positive, the test shots were top. The device can be "intuitively" easier use than my old Metz, finally fit the batteries (Varta!) Neatly into the tray, which is also much more comfortable to open. The YN has indeed not switchable, front flash white when 54MZ-4, but I will probably never miss, especially since the YN is significantly faster flash ready. The focus with the AF-LED light Cross works better and more targeted.
Everyday life will tell how long does the device, but the impression so far does not speak against a long and frequent use. And because I could save the flash, I also treated myself to two wireless flash trigger by Yongnuo YN-622: the best!
Conveniently, I would otherwise like to join in the good and detailed commentary by Andreas K. (1/14/2015) - with me but did not have the data sheet with German instructions, that was a English. Quick Start Guide.
