This flash, friends who know how to do, are not worse than the original factory. Support ETTL, it is an automatic flash, even the flash performance is powerful, and the charging is fast.
For more specific performance, I think there is a more detailed introduction on the Internet. The cost -effectiveness is certain. Canon native to the micro -single light is more than 500, and the level of this light is about 2500.
There is no invoice in this light, the packaging box. If you care about these friends, please float.
