A must for all owners of a system flash.

I bought the transmitter as a supplement to a 2er Yongnuo YN 622N I-TTL wireless flash trigger set and the decision not regret it! I dissolve in order from a Yongnuo Speedlite TTL flash and a Metz AF-2 digital. Reason for buying was the user-friendly LCD screen - making it possible to intuitively configure the transmitter - unlike the YN 622N transceivers, which must be configured through cryptic codes. For three groups you can configure the flash output, correction and zoom independently without much effort .. TTL is supported, as well as the high-speed sync (HSS) - provided an appropriate and suitable flash camera. Another positive aspect is the (switchable) Auto Focus Assist. As a benefit I find the battery indicator. My Eneloop / Pro batteries (2 pieces) keep for several weeks, until the prophesied the imminent end. Interesting is also the possibility of using the transmitter as a remote shutter - assuming another transceiver. I do not use this feature because I always have a pixel remote release it.

Shortcomings: the size of the transmitter could be a bit more compact. When locking wheel I hope it does not break off at some point - it could be something catchy. The backlight can be activated automatically when operating the shutter / Fokusierknopfes the camera.

The quality is really top - the low price does not see you at the transmitter. The price / performance ratio is outstanding. Even for much more money do not get much more commanded you.

In short, can do much wrong really.
