Clone with nice extras!

Usually I do not like it so much when copying so shamelessly.
In this case, however, it is done with some additional features; why Canon has not already done with its E3 RT, know that hope in Japan.

Housing: grabs not quite as wertig like the real thing, however, is okay.
Juxtaposed (yes, I have also the original) must be to look very closely to distinguish them.

The AF-assist illuminator: makes a very different pattern, as I know it from previous Canon flashes; It usually works.
Mostly: depends on the distance and the camera and lens.

The group mode for cameras before 2012 (in my case the 1D Mk4): Works!
Although was not the big problem, but it's nice when I do not have to change even in the head modes, if I change the camera.

2. Curtain: yes, work in manual mode.

What further fascinates me: the original triggers the flashes in manual mode only when it is sitting on a Canon.
The Yongnuo triggers (from firmware version 1.08) with other cameras, such as a Fuji X100s- and there opens up very interesting possibilities .....
and the setting values ​​are transmitted wirelessly!
(I myself have not tried it, is in the Fuji Forum described as very reliable functioning)

Yes, it's a cheeky copy, but with very nice additional features.

Oh, I almost forgot: has a USB port.
For more updates.

Great device- unequivocal recommendation to buy !!

Update 03/18/2014: Now that I have the X100s own: the Canon 600 RT can be triggered in manual mode through this device.
The change of power takes place via radio: Setting the strength, once on test press (= transmission and it will flash) - change at lightning arrived.

Am thrilled!
