Yongnuo YN-622C Controller Trigger

I'll do some tests with a digital multimeter... I'd like to figure out the behaviour of these unit with ni-mh batteries by myself.
If you interested in some details please let me know, I'll post them here.

I'd be curious to see at least:

-idle current (mA)
-current while communicate (mA), or (even better) total power used (Wh)
-power used while trigger (Wh)
-max voltage dip during communicate and trigger (dV)

Especially last with both NiMH and alkaline would be good to compare.

Almost LIVE on it

Hey friends,

My first pair of YN-622C have just arrived! I look forward to testing them and using them 'on the field'. Thanks for all the resources here, and 'the other user guide' as well!

I was curious about something:
- I have a T2i, which is a Type A camera which works great
- I have one 430exII which is a Class I flash, which works great
- The other flashes I have access to (borrowed from my father with whom I work) are a 430ex which is a Class 2, and 420ex Class 3 flash.

Our usual working condition (since its on the field, no chance to set up a complex studio light) is one flash on top of the camera and one flash off camera. Up until now it has been my 430exII on the camera and a Vivitar flash mounted on an optical trigger (dad's own design!). We have used this combo to great success, but the Vivitar is a full-power flash, no manual control, so I adjust the on-camera output and adjust ISO and aperture to provide correct exposure.

I'm looking forward to evolving into this new setup, which will be more versatile and will allow me to keep the aperture to my chosen DoF instead of for flash compensation, but I was wondering what my choices are in regards to on-camera control.

If I use a full ETTL setup and set the off-camera flash to the 430ex (I) on group C and use it as A:B C to set FEC on flash, will changing the FEC be equivalent to changing the 'manual' output on the 430ex? How would I then change the output on the on-camera flash? Within the flash or would it respect different A:B ratios even if there is no B group set-up at all?

If I go the other way and use the 430exII on the off camera RX and the exI ontop of the camera, would I be able to set in-camera manual settings for the 430exII? How would I control the on-camera exI?

I'm kind of confused regarding this mixed up Class 1 and Class 2 flashes (lets forget about the Class 3 for the time being) specially given the on-camera flash. Is the on-camera flash a different beast or is it just as if it were a Group A put on a different RX?

Thanks for any input, and sorry if this is confusing or flat-out wrong, I'm just getting a grip on things (but I have read as much as possible, not trying to get an 'easy' answer without doing my research first ).

Thanks again,
Rafa.

Set FEC from the camera's menu or directly from the LCD of the 430EX II. Or both, as FEC is additive with the 622.

Someone will correct me but I think if the whole system is set for remote manual control from the camera's menu, the on-camera 430EX would have its manual power level set from its LCD.

In The system "Camera + YN-622 +430 EXII" always acts priority of camera settings.
Directly on the flash you can not change the settings.
except for Zoom setting(if the flash is set on the transmitter)

But if you turn to the MIX MODE, will be to act the priority of flash setting .

Sorry for my bad english!

That's what I wasn't sure about. Thanks for the correction.

Thanks for the input! The FEC trick worked, but it appears to affect (as I would expect) ALL the flashes in the setup, so, if I want to control output ratio from A with FEC I need to compensate the FEC in C the other way to keep its exposure.

At any rate, these new little babies appear to be really excellent!!! Very happy with my purchase. Looking forward to discussing fine tuning after a few tests.

Best regards,
Rafa.

I purchased a second pair of 622's after receiving a set from my daughters for Christmas. At the moment I have one extra unit and find it's a handy trigger for using a flash meter. I put it in mix mode so it won't interfere with the manual settings on my two class 1 flashes. At the subject's position, I can press the test button and take a reading without having to fire the flashes from the on-camera 622.

I just got my YN-622C and just from the brief test to make sure they are working I am very happy with them. I had seen someone say you can't use the wireless commander from the 60D which had me a bit upset. Whether or not the person said that I am able to use the wireless commander and access functions of the YN-622C e.g the groups A, B, C. Overall I am very happy and will by another set when I get a chance.

I see a warning in the manual indicating that you shouldn't use these on strobes with anymore than 300w, has anyone tested this cause I am looking to use these of 400w and above strobes in the near future?

This technique is described on Page 8 of "The Other YN-622C User Guide", V.3.

The test button does not change any flash settings. It is a simple Fire! only function, sharing the functions of the simple trigger which lets it fire a Nikon flash from a Nikon camera.

Only the 622 on the camera can be in Mix or Remote mode. The setting is ineffective on other units.

I printed your manual and will give it a good read this evening. Thanks.

I must have inadvertently bumped the shutter button on the other body before I removed the 622 (that was in E-TTL mode) to use it for meter triggering. The slaves flipping from manual to E-TTL made me think I had to set mix mode on the spare trigger so as to not affect the slaves. Further testing showed, as you indicated, that the unattached 622 doesn't affect the slaves' mode.

That means not to exceed 300V (volts) at the sync port. It's not referring to the watt second power rating of the strobe.

I'll try, I hope to take measurements correctly.
I'm curious too...
This weekend I hope to feel better to do some tests (I had a flu)

The YN-622N version for NIKON is Official!

Should be interesting to see what they will be capable of. The lower priced Nikon options are pretty limited otherwise.

Of course what would really be nice, but probably unrealistic, is that a Canon camera could control a Nikon speed light via the YN-622 interface. PW ControlTL claims some limited cross platform interworking although I've never talked to anyone that has used it.

Does focus assist only work in the auto modes? I can't get it to work in Tv or Av. I have a 7d. The C.Fn setting for AF-assist is enabled.
