Yongnuo YN-622C Wireless TTL Flash Trigger Transeiver for Canon 7D 5DII 5DIII 1DIV 1DIII 5D 2.4GHz 1/8000s

Partly works with my 6D and two 430EX II. Indoor fairly lit ETTL works. Darker circumstances and sett to A:B something happens and group B fire at 1/1. Have changed/reversed receivers/transmitter and flashes every possible way but still the same Group B fire 1/1. Turn on some light in the room and it works again.

Have changed/reversed receivers/transmitter and flashes every possible way but still the same Group B fire 1/1. Turn on some light in the room and it works again. Making a hard reset on any YN622C (press Channel and Group selector simultaneously and hold) make it work in the "dark", one time then its back to Group B faults. Set to "ALL" no problems. Group A:B + C works but i have only tried with one flash in A:B, and dont remember if I tried booth A and B group on the reciver. This problem when its "dark" doesn't occur on the 60D I've tried it on. But overall one have to bump it 3/4 to 1 stop to get the same light as Canon "normal". Manual it seems to work as it should. My YN622C is marked "2014 Dec". earlier versions did have som sorts of other issues. Check out http://photography-on-the.net for better Manual than the accompanying Youngnuo manual. see less

Canon, Nikon and Pentax each have their own TTL flash metering systems, respectively E-TTL, i-TTL, and P-TTL. They all use a weak pre-flash that is metered and used to calculate flash power level required for correct exposure. E-TTL = Evaluative "Through the Lens", i-TTL = Intelligent "Through the Lens", P-TTL = Prefl… see more Canon, Nikon and Pentax each have their own TTL flash metering systems, respectively E-TTL, i-TTL, and P-TTL.

E-TTL = Evaluative "Through the Lens", i-TTL = Intelligent "Through the Lens", P-TTL = Preflash "Through the Lens". All three are pre-flash based evaluative flash metering systems. see less

You have the option of purchasing singles, pairs or I have even seen some package three together. However, for the apx $80 you are referring to includes a pair of triggers. Good luck!

Hi Before we continue givibg suggestions. What flash do you have? I know you have a canon 6D and yn622c.

The comments about the 622 are correct. However, there is an additional option: the 622C-TX. This transmitter (only) unit is designed to be an alternative to the ST-E3-RT. I don't own an ST-E3-RT, but shot with someone that had one. The ST-E3-RT and the 622C-TX are functionally very similar. You can control the flash u… see more The comments about the 622 are correct.

You can control the flash units through the camera menus, and you can also control the flash groups and multiple settings on the 622C-TX unit directly. see less

Don't know much about Vivitar Flashes but I doubt it. The flash (it self) would have to be ETTL of course but there are two models of the 622 C & N 1 for Cannon and 1 for Nikon your best bet would be to purchase a Yongnuo 565 EX flash also (about $105.00).

Actually I have found the 603 & 560III flash (in manual mode) gives me much more consistent results, but then again I rarely shoot on camera flash see less

I cannot speak to your setupI have a Canon 5d and a 600 flashit does allow me to do second curtain high speed syncI believe the 60 dwould be okay but I'm not familiar with a 560 flash

Yes Thank you

No idea, but their flashes are very nice and worth it.

By Seneca Riggins on May 16, 2018

it is compatible with flashes that have HSS. for example, with my yn568 II it can sync up to 1/8000. but with the yn560 it will not have HSS
