The triggers are sold as a set, ie there are two transceivers in the package. Although is in the text, but I was not sure because of the price compared to other vendors is very low.
I run to the YN622:
Canon 5D Mark III
Canon 430 EX II
Yongnuo 568EX
- Everything works perfectly, the flashes can be completely operated by Ettl and also manually.
- The YN622 grinds the flash by, that may in the trigger on the camera even a flash or eg Yongnuo RF-603 are plugged
- It used standard AA batteries, not like the RF-603 exotic batteries
I had read the manual trigger RF-603 were all right. However gat annoyed me that I always durft run to flash for changing the Bltzleistung - which is especially annoying when the flash is mounted on a tripod in a height of 2m. The YN622 I can operate the flashes still manually adjust the camera's performance - is of course only with ETTL flash.
NOTE: The trigger has no screw thread, therefore can not be like the RF-603 screw on a tripod. For the order the best "Walimex Universal hot shoe", currently costs 5.99.
Was delivered after about 10 days, that is, as previously announced.
The package arrived from the UK and therefore I had no contact with the customs.
ADDENDUM:
Neulichst we triggered lightning in a shooting by an analog medium format (Mamiya 645). That was not a TTL / eTTL trigger, but the lightning has ignited properly.
