This wireless trigger is worth the money. So you could make up my impression of the parts shortly. I have the transceiver unpacked batteries pure, a portion with a flash on the camera second part with flash on tripod and behold a miracle, it will flash. Great, I thought now try on you, if can also be initiated on the transceiver and what can I say, it was not. Neither of the on the camera still from that of the next stand. Oops! I had forgotten to connect the camera to the transceiver using the supplied cable. At one time it was exactly as it should and even more, I have selected in the camera settings when triggering "focus priority" and it also flashes only when the camera has focused, SUPER. Without camera these things do not work, so only put everything together then test. The combination devices also did not have a bad visual impression of the haptics her anyway (not construed so all too often on). I have no fear that because of the lack of clamping stations including lightning slip of the camera is shaking virtually nothing. Well, that and the flash on the camera is not supplied with the TTL signal can be annoying for automatic clippers, I do not mind. Yes, it is a pity that the sender of the camera's internal flash can not be used, but can at plugged-in Flash Yes often not be opened. In my Nokon D7000 the transmitter should not be wider than the hot shoe and not higher than the rail of a hot shoe so in my eyes at the moment not technically possible because switching button, diodes, batteries need indeed place. The specified sync speed 1/200 but failed the set are also OK. A word on the power button is mounted Although not quite advantageous but even I'll go with my sausage fingers with attached flash (FL40 Olympus and Metz 44 AF-1 digital) ran. The delivery was fast (9 days). Together with the transceivers I ordered a flash in a German photo dealers, this was because 2 days earlier. Because of the lack of TTL pass-throughs and not quite as fast sync time as indicated I was inclined to give only 4 stars but the price is the hammer therefore. 5
