For anyone who does not want to have on the camera's flash !!!

Apparently Yongnuo is a very efficient manufacturer, in particular as regards criticism. as they have here largely solved in version 2 the major problems of its predecessor. This means you can finally screw the small and the wake-up / test button is stehts accessible. The setting of the channel remains cumbersome as there are small toggle switch in the battery compartment, which if you have shortened fingernails, hardly gets allocated.
The additional outer makes a high impression and thanks to the small size, this fall also hardly on the camera.
As a final point, there would still outside the on / off switch, which rounds off the exterior features.

With the on / off switch, the remote trigger can to logically and from switch. Just stupid, that makes a total of three positions ..... So On, Off and nochwas ..... until I came behind it took some time, because the instructions for disposal is.
Position 1: Off
Position 2: Sender
Position 3: receiver
Actually quite simple and logical, but insufficiently explained.

But now to the most important and eigebtlichen function, triggering a flash. Basically, it works flawlessly. Attaching, switch to the correct position and losblitzen .... work. Super ..... But two things you should know in advance so as not to be disappointed.
1 .:
This Funkauslöser transfer only the Singnal..Blitzen. Should one therefore a TTL call his own brings an absolutely nothing, because no further information is transmitted from the camera.
For me, this was not a problem, because I always highly individual place my flash and the camera the correct settings eh can not meet, or why should I, if I determine all the settings on the camera, over Belichtungfszeit, Aperture us ISO itself, the can regulate from the camera flash intensity.
A point I've only recently discovered is if you the more expensive Funkauslöser of Yongnuo fetches, you can simply transfer TTL information. So far so good, the interesting thing is that you can buy a transmitter, the flash settings mitsendet. In other words, you do not always run to the flash to change the settings, special does so directly on the camera. That's another issue ... All thing easy questions in the comments.

Not all flashes are with radio triggers, or with these triggers. I initially borrowed a friend Nissin flash with TTL function to incorporate me into flashes before I spend any money. Just stupid, that just this flash does not support remote trigger. Therefore, I can only advise everyone to ask in forums in advance, he should already have a flash or to be purchased a new. The Canon and Yongnuo flashes to my knowledge, one should by no need to worry. but this information without guarantee.
The range of 100m, which is advertised here, I can not confirm, but let's just say, in a normal setup, I could not notice any problems. Therefore, you have to worry about it. And honestly, who needs 100m)

So what can ma say to these radio triggers and for whom they are the right ones. In my opinion, for anyone without restriction. They do what they are supposed: Send A flash signal from A to B. The some flashes are not supported, can both Yonguo, as well as to the manufacturers of the lightning are and has no impact on my rating.
Therefore, I can only say that you will find for this price nothing better.
