Yongnuo Duo Fire Flash Fast
In either case they work effectively with the respective TTL flash systems for these camera types. They provide 7 channels in 3 groups - can throw out AF lights to help focus - and can do high speed synch. Of course you can always switch to manual control as well.
You'll not on the packet that it shows a separate PC connector socket at the side of the transceiver - this is very useful if you are also triggering off studio flashes or older -odder - units. As with many of these control boxes, the more options you have the more useful it is - there are all sorts of things that we think up later on in using external flashes, and the less adapters and blocks you need the better. It gets to look like Heath Robinson as it is.
