I sent my 430EX I retire, and decided on the Metz. Only I'm not sure if that was such a good decision. When the first pictures with my 7D and a Sigma 50mm f1.4 still all was well. Apart from the fact that lightning has already revealed a small software error. If you do not flash over to EV 0 when you turn off the camera, he can no longer control the camera the next time. You have to set the flash to the unit to 0 then first ... Well, you can live with. Evil it was then, when I used a telephoto lens. From 120mm of lightning illuminated only through. He simply burns off 100%. Remedy can create only if one adjusts the flash manually to 85mm or less. The fault lies to reproduce with another camera and another telephoto lens. Both errors are known but in Metz, an update will come in January.
After approximately 200 images then was quite final. The flash has its service completely adjusted, let himself still on, but no longer triggered.
I have once again decided to go anyway for Metz. Feel and operate like me just very good. The display can be operated with gloves even in freezing temperatures. And I just like to buy products from Germany. The AF-assist beam is very weak, but together with the 7D super fail.
