Not wanting to spend $ 600 in a flash of the brand, so I made the purchase of a first flash YN 568EX to see.
I am amazed.
Powerful Hyper (NG 58), easy to adjust, fast access to settings, functions ETTL (and the photos are well exposed) ability to move up or down to 5There (Canon is 3IL memory).
Trappe easy battery charging on a wedding .... everything possible to be faster is welcome .....
Commissioning for the first lightning fast, same for the next lightning .....
Solid construction, orientation of the flexible head and well damped.
Short but good on the basic settings ... I have not yet tested the advanced settings (1st and 2nd curtain .....)
A 2nd arrived in the bag ... in case ????
