I got myself this flash, because I wanted the one hand and performance on the other hand was not ready for the money to pay a Canon 580. I must say that I was not disappointed. The flash output is impressive and the menu structure is very simple. So you need also no German-speaking guide. The only thing that was not entirely clear, the various slave modes are. Sc represents slave of Canon, Nikon Sn (if you want to borrow the flash at times Nikon-friends, they can at least unleashed flash) and S1 / S2 for slave function without TTL. The camera detects the flash problems (60D), so that the automatic zooming in the flash also goes. Zooming of the flash is a bit noisy, but I think that is no different in the Canon flash. Who does not daily needs its flash (professional photographers) takes the Yongnuo a great flash of incidentally HSS and master function support (eg what the 430 can not).
