The more I read the more I'm getting confused so I'm hoping someone can help me out. I'm expanding my flash capabilities and I'm looking for a flash that satisfies the following (in no particular order) ...
1. TTL (mostly because I understand that you need this to be able to fully control the flash from the YN622-TX)
3. 2nd curtain
4. External power socket
5. Works with Yongnuo 622c triggers
Currently I have a 430 EXII and a couple of Yongnuo 560 II's. I'm pretty happy with the Yongnuo stuff, works well and a good price so I've been looking at their current line up. I can't seem to find one that matches all the above. I can see that the YN565 EX II covers everything except the HSS and the YN568 EX covers everything except the External power socket. Can anyone tell me if I can satisfy the whole list. If not Yongnuo, does anyone know if I can get a third party flash that will do what I want please?
