The setting is really interressent for all kind of on photos.Bien have to play with, touch all the buttons briefly to play with. Then you must read the manual, and seek to understand how it works, do not hesitate to read other books to understand aspects techniques.Son operation with other flash is beautiful, or, for an interior studio with a transmitter 2 or 3 .The automation with eos are really very good for beginners, For the Pros and Experts is a regalia, either a manual, Syncro high-speed or 2nd curtain, without setting auto wire, radio or optical transmission. We work with several little flash groups on several channels .In outside it is very good with wide angle or telephoto 200 m / m or more, the power setting is impeccable for macro example .. The only problem that some stop purchase, the price, yes it is expensive but at least it's very good. YT
