Just bought the Yongnuo YN568EX III and used it for the first time at a glamour/model shoot. I set my camera to 2.8 and tested out the high speed sync capabilities of this flash. Outside without a diffuser on TTL it was overexposed. Set the exp. compensation down and it worked great.

This is an awesome flash at a great price! On camera, off camera, optical master, optical slave, it does it all!The "In the Box" section only mentions the flash and stand, but a nylon sleeve/bag is also included.

It works with my Nikon D5500 perfectly. TTL mode also works. The flash provides a very powerful light. No complain at all so far.

This speedlight has served me well. No complaints at all - it works well with both my D90 and D7100 bodies.Mel - I did an accidental drop test last evening (3.5 feet on to concrete), just prior to shooting wedding engagement photographs for my son and his now fiancee..

This speedlight replaced my trusty YN568EX II (which was heavily used and gradually developed a loose-ish connection between the hot shoe screw and unit itself); the old unit still works, but would have a limited lifetime with continued heavy use -- it is now my backup unit.

This is the best speedlight for its price. It is TTL and able to support high speed sync (HSS). The only thing I don't like about this is its battery door which looks brittle and may easily break when accidentally dropped.
