Tested ETTL / High Speed ​​Sync and bought later!

For quick reader:
Plus: On my Canon 6D and flash the parts create problems Ettl and High Speed ​​Sync, Practical battery size, groups and channels and more set ...
Minus: manual - well; Glossy surface (slightly scratched)

Really great things. I am plagued by the first "Cactus" flash triggers, then have the first Yongnuos (the previous generation) changed (and never had more problems).

Then why this? Can be divided into groups and trigger lightning from afar - especially in celebrations a great thing!
ETTL with remote flash works (no more red eyes) continues.
Works Even the high-speed sync with Canon flashes (with others I have not tried).

Tip. High Speed ​​Sync is for me a little bit the holy grail of exteriors: You want to position the model in the backlight, but open the aperture (for background blur). As a result, the exposure time is reduced. Now there is a problem with the "sync speed" (Those who should be interested for details sometimes look for my blog post with the keywords "Zero Brain as the bar is on the picture").
"High Speed ​​Sync" circumvents the problem: with the disadvantage that the flash must give everything up and the batteries run out quickly sucks (it also creates not the same performance as in "normal" mode).

PS: the writing of this review took more than an hour. It was important for me to type up any specifications, but represent what motivated me to choose this monitor and if the bill came up. Should I forget something, I am pleased with corrections in the comments or by email. "Helpful" ratings are the spur, not tumb squatting front of the TV, but here provide information for others. So it would be nice .... ;-)
