Yongnuo YN-622C Controller Trigger

Is there a 3rd party flash compatibility list being built anywhere?

Yongnuo should really do something against this store. Fishy business.

Agree! they fooled me... I wanted to order straight from Yongnuo so I went to The Yongnuo Store instead of going through eBay. Took them 5 days to ship the item. From now on, only eBay.

I hope they also give 1 year warranty. Now when I look, it doesn't say it anywhere...

How long is the wait from ordering to receiving?? I am on the road and need to time when they will arrive or else it will be many more weeks to wait so I can play with them. Haha.

My experience ordering things that are shipped from China via mail is that the delivery window is quite large. At least a week. Scheduling a purchase based on delivery in US via mail from China is going to be a challenge. And, unfortunately, other means of shipping that may offer a tighter window appear to be quite costly.

It might be more practical to have them shipped to your home, then have someone forward ship them via UPS or FedEx second day.

Can Clive and anyone else help confirm the On - OFF situation with the 622C.

With Pixel Kings its pretty obvious when they are switched off, but still mounted on the camera hotshoe, that they are not completely OFF and still effect the camera settings.

I have not noticed this with the 622, they appear to be switched off completely when still mounted. Has anyone noticed they still have any effect on the camera? With the Kings for instance they can even effect the TTL exposure while still mounted.

Would these YN-622C support my two flash types of shooting:-

1. Outdoors: Canon 7D + 2 remote 430EXII's
a] Can I have 1 in group A and i in group B with ETTL and Ratios and HSS
b] Can I have 1 in group A and i in group B with Manual Flash Control and Ratios and HSS
c] Can I apply FEC to the 2 above styles? either globally or individually.
[reason I'm doing this is to go radio transmission and avoid line of sight issues and the 'wireless busy' delay fault.
Requirement 2 sets of 2 YN-622C [I.e. 3 units, but have to buy pairs]

2. Portable / Home Studio: Canon 7D + 2 Bowens 500R Monolights [Strobes] connected with a pc sync cable to YN-622Cs + 2 remote 430EXII's wirelessly.
NB the Bowens can use an optical slave either set to on or off, can be set to miss the first 1-3 optical preflashes [except the Canon wireless preflash for some reason], also has pc sync cable socket.
a] Can I have 2 Bowens R500s in group A in Manual Flash Mode [I will set the power levels from the Bowens remote control unit for 'ratio' control] and one 430EXII in group B and one 430EXII in group C; with Manual Mode settings for the 430EXII's (only) controllable from the camera?

Requirement 2 sets of 2 YN-622C [I.e. 4 units] or maybe one pair if I got the Bowens to be fired optically i.e. from one of the 430EXII 's flash's (latter idea might be interesting, as I could try out I pair first to see if they work for me)

3. Do these units, when in Manual flash control mode, send out or get the speedlights to send out any optical preflash signals (I am assuming they would not) - this is related to using a Sekonic L308S flash meter. NO problems with the Bowens as the remote controller can let me do what I want i.e. turn them off.

I assume in ETTL mode in the outdoors scenario it will generate a bunch of preflashes from the 430EXII's.

Sorry for the long post but as a flash newbie I would love some kind experienced people to double check this product will do what I want [the previous 20 pages blew my mind]

For those who are interested, set the camera to P mode and turn on/off the receiver, then take a picture, you can get a clear answer.

The hotshoe of YN-622C is almost the same as the one on Canon camera. That's, if the flash mode (of the flash) is ettl-ii, it will emit a preflash. If the flash mode (of the flash) is M/Multi, it won't.

Thanks... so no Sigmas tested yet.....

Submariner - lianggc has answered one aspect: Canon behaviour has been largely preserved. There is more than one "pre-flash". One is actually at "shutter-open", saying Fire now, and is not needed under radio comms.

E-TTL is a group of facilities, including auto exposure evaluation, and FEC, and Canon Ratios. FEC and Ratios do not apply to Manual power level operations. (Canon ratios depend on multiple exposure evaluations by group - a TTL operation. FEC is a user adjustment to the TTL evaluation. Other camera brands work differently - they don't hold the patents.)

HSS is available under both ETTL and Manual.

YN have extended the Canon approach (whatever the merits or demerits of that is) by providing a "Mixed Control" which allows photogs to use ETTL and Manual and other settings in ways which Canon tried to limit. Kudos.

Within the logical distinction of the ETTL feature set versus Manual levels, you should be able to find configurations that do what you want.

Anyone tried this triggers with AB's?

It appears they will fire just about anything with a sync connection via the PC port.

The "hyper sync" aspect may be iffy.

When I get mine, I'll give them a test with an Einstein. It doesn't play well in "hyper sync" world because of the IBGT power control, but I can at least confirm that it will fire.

Hyper sync is what im looking forward...

is that possible with the yn622?
