There is no way for the user, or reseller for that matter, to know. Only stock control by the retailer.

Thanks Clive, ummm how do they run QC; but then they are $82.

They have increased their QC team and training. I suspect that the problem is that they have been re-burning the firmware in dealer-returned devices. So the numbers will be all over the place.

As long as dealers act competently and honestly, the small number of units that had a problem transmitting from 1D series will have passed through and will no longer be an issue.

YN makes mistakes. With the 622, they have acted very quickly to fix them.

Did you say that the version 1 of the yn-622 won't change the manuel power settings on the yn-568 from the camera. That is what I think you said.

David Thanks for taking the time for such a detailed explanation.
Does that mean I didn't help myself by getting 1x 250R and 1x 500R if I want to use supersync. i.e. is my logic correct that I would have been better off getting 2x 500R's and running them at 1/2 power?
Bit late now but interested to see if I am getting the hand of the science.

Yes,
Look at the T.5 times in the specs, the 500R has a longer time the the 250R if I recall its like 1/900 and 1/1100.

I checked my references and find that my recall was faulty. the references are from 2004-2006, and were support by Canon insiders, so it seemed likely that they were right.
1. Both shutters closed.
2. Second curtain up to clear sensor; 1st curtain still covering sensor.
3. First curtain down. When fully down, flash told to fire.
4. Second curtain down to cover sensor. Exposure ended.
5. First curtain up to also cover sensor, ready for next shot.

But the over-x-sync shadow is at the bottom of the image, you say? Yes, because the lens inverts the image so the bottom is at the top. The file writing procedures re-invert it for us humans. Imagine chimping with an upsidedown image!

So, it seems that David is wrong on this point. Sorry.

I could be, but in addition to looking at the way the shutter moves in my 5DII I did some empirical testing. On the page on my tutorial website I have two images that illustrate where the brighter light is by using a MacBeth color checker and turning the camera upside down to make the shot. And, when I was doing beta testing for Pocket Wizard MC2 receivers on Einsteins. All the shadows were at the bottom of the image.

I have no idea about the two shutter curtains covering the sensor. When I look at the sensor in the 5DII with the mirror locked up. it looks like one shutter curtain. when tripping the shutter the curtain snaps to the bottom of the camera. When the exposure is complete a curtain descends from the top of the sensor across the sensor. I'm sure that then the shutter resets. The 5DII shutter curtain is a group of about 5 what look like thin metal leaves.

just doublechecked and now it's working...not sure why it wouldn't work the first time

All the YN-622 works with 568EX on non-1D cameras, only the earlier versions won't work on 1D series.

Explain a little more on this, we are a small company and can't afford to buy and test all the camera bodies. At first, some of us don't expect 1D users to use our products as they think the 1D users are rich and will buy more expensive ones.

This issue is fixed and all the 622 from us in Sept are OK. It won't impact those users without 1D.

Vnation, how about with wireless enabled? As I know, some camera bodies limits the response time of flash while wireless is disabled. That's why we suggest to keep it enabled when you don't use 2nd curtain sync.

Okay, thanks. FEL is working after I enabled the wireless again.

Yep, same here...

sorry, my apologies.

-works very similiar to the canon counterpart.
-the battery tray orientation is a little odd, but nothing that would worry me.
-the AF grid is the same as the 565 and YN622's.
-The build seems a little "boxy" opposed to their previous models.
-The siren feature is a nice feature. It's easily controllable from the yn622C.

Thanks for the review!
I was somewhat alarmed words that uncorrected YN-622 can not control YN-568 in manual mode.
But it seems you just hurry with conclusions.
Thank you very much for the information.
In the near future I myself will use YN-568 + YN-622.

Not sure what T.5 is but I assume you mean what Bowens call the "Flash Duration" and your respective numbers are correct. Well on the positive side one learns something everyday.
Shame really as they are identical except for the capaitors [apparently] hence a little physical weight too; so they were only £60 less .
In my ignorance they did advise getting another 500R, but did not explain what you have; and as there was way plenty light output I stupidly thought why bother if they are the same build quality. Plus 2 in a realy solid padded case are jolly heavy.

Its been 2 days since i ordered my yn622 with hk-econcept. it has not been shipped till now and the dealer is not responding to any of my mails. Terribly restless and waiting with my fingers crossed......

10 days for me...it's been "processed thru sort facility" for almost a week...can't wait to get them. I ordered from the photogadget.

Hang in there. I ordered mine Aug. 24, should arrive today. Said order was lost after mailing, but clearly shipped sometime later, on Sept 5 according to tracking info. They did respond to my emails pretty well. Good luck!

There are two flash duration times that manufacturers use. One it t.5 which the time that the light intensity is greater than 50% of the total output. the second is t.1 which is the time that the output is greater than 10% of the total output. Here is a link to a page on the Buff website that explains flash duration. Even if you don't like Buff as a manufacturer, this is useful information. http://www.paulcbuff.c​om/sfe-flashduration.php

The diagrams on the left of the page graphically illustrate the difference shapes of power curves as power is reduced for voltage regulated strobes. Also, IBGT which shows why they are not good lights for Hyper/Super Sync.
