Now for the points which I have noticed in direct comparison with my Canon 430 EX II.
The look and feel can I find the Canon somewhat "rounder", that would not bother me, however, because the Metz is really well made. Only the battery cover, in particular the designation of the positive and negative terminals, I find the Canon but really handled better.
The difference in the flash foot, the Metz is made of plastic and with screw, would not bother me because it was anyway planned only as a second flash.
Operation of Metz is naturally quite different solved, especially since he has no display. But I have known ahead of time and asked for me is not a problem, since I already can do well on the camera settings.
What I liked better when Metz is that it has more rest units during swiveling reflector.
When taking pictures in portrait mode, it can also be easily swiveled backwards at Canon is here at 90 degrees Final.
What finally persuaded me to switch to a second Canon 430 EX II is that the Canon in slave mode obviously more sensitive than the Metz, the control the Canon 7D has taken.
The 430 EX II is dissolved even at unfavorable angles between camera and flash off yet. Since I intend to occasionally use both lightning in slave mode, it is better if both respond the same to me.
Conclusion:
Definitely a good alternative to the Canon 430 EX II. I would also keep him safe if he had responded in slave mode just like the Canon.
