Have the Yongnuo Speedlite YN-565 EX II flash - E-TTL flash for Canon EOS DSLR now good 2 weeks in use and can only tell the best. Ranging from the very appealing and careful packaging, about the fact that the unit has run at all, that all functions work as well, as it should be, that the illumination (that matter actually) is impeccable, the Lightning received a very professional impression. One tends the SG brand devices to prefer but they are built (for the 6-times the price) obviously in the same place and by the same people as the Yongnuo devices. Thus, the issue has been clarified what is better. It is the same!
On the technical details I will not go into here, of which there are more than enough to, for example Youtube. Due to the quality of the product, through careful processing and the laudable commitment from the seller of the myth is branded as we understand it, destroyed. There is the difference no longer whether it is a loving or not.
