### First Impression:
The 568exII comes in a compact package, it lies a held in bad English and Chinese user's guide, some of which is really needs. The device has, for example, various slave modes and only on the basis of display names can hardly be seen what Sc / Sn / S1 / S2 means. The housing acts as the less valent 430exII, the plastic is more gray than black and looks a bit "cheap". Solid does it look anyway.
The YN-568exII is a little larger than the 430exII. From 430exII one recognizes again some controls, but not all. The attachment to the hotshoe via a thumbscrew, which I personally like worse than Canon's quick release. You have to tighten the screw, otherwise the flash can wiggle a bit. It can not easily fall out, when tightening also the locking pin in the shoe lowers.
There is no lock button for the tilting angle or rotation of flash head, although the head snaps to predefined locations, but you can do it then just keep moving with low force. For me, not a disadvantage for Canon flash, large weights should be attached to either of them. Positive is that you can turn your head in both directions through 180 °, the 430exII the rotation is limited to right at 90 °.
One last small difference is that a button must be kept pressed while YN-568exII on / off, the Canon there is a sliding switch that something better should be protected against inadvertent operation.
### First tests in conjunction with EOS 60D:
The wireless operation works without any problems, both in the ETTL and in manual mode. If you are the instructions by reading short and clear, how to get in the ETTL slave mode and optical slave mode (without ETTL), both goes smoothly. The maximum flash output is appreciably higher than the 430exII, and you can turn down to 1/128 (430exII: to 1/64).
A smear should be done at HSS mode, although the works, but here's the YN-568exII slightly fainter than the 430exII (tested at 1 / 8000s) and he also needs about 5 seconds between two HSS-tripping to relax , The 430exII has no problems with sequential shots with HSS flash (approximately 1 second interval).
For this, the YN-569exII unfortunately not show a distance has that indicates the effective flash range for the selected combination of flash intensity, flash zoom, ISO value and aperture, which has 430exII this.
One advantage of 568exII opposite the 430exII is the ability to strobe flash (simply adding power, duration and frequency on the display a), and the optical master for Canon and Nikon flashes. The latter feature was more important for me, because I almost unleashed only Funkauslöser (YN-622C) tripping. The strobe flash is nice, do not know how many times you can really use.
In all other features (second curtain sync, power control, zoom, etc.), there is effectively no difference between two flashes.
### Conclusion:
The YN-568exII provides extremely much power for a lower price than that of the 430exII. I'll keep him therefore who were key points for me:
+ Strong flash output, ETTL capability
+ Price
+ Built-in optical slave
+ Stroboskopfähigkeit
+ Wider angle of rotation of the head
- Haptic
- Power / not as a sliding switch, locking screw on instead of quick release
- (Little) heavier and larger
