is that possible with the yn622?

I have no idea... LOL

Hyper sync is what im looking forward...

The "Supersync" timing as YN call it is similar to the Kings and Odins etc.

The AB1600 would be fine, the issue is more the 5DII is not ideal for this. You may get reasonable results, but a 7D or similar crop camera would likely do quite a bit better.

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.

Ok Thanks, yes this shows the 622C are switched off unlike the Kings.

Yes.

"Hypersync" is a Pocket Wizard system. Yongnuo call their similar system "Supersync". With shutter speeds above x-sync, it will fire a flash connected to the PC-sync port before the shutter has opened, to provide light while the shutter slit moves across the sensor. However, it does not provide adjustments to the timing.

So, a studio strobe set to 1/1 power level to give maximum burn time is likely to last long enough to cover the entire transit of the slit. If the electronics of the particular strobe allow it.

A hot-shoe flash typically has a shorter burn time, and should work for 1/1000S to 1/8000S. Between x-sync and 1/1000th, there may be a significant fall-off at the end.

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.

Thanks Clive.

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.

Requirement 2 sets of 2 YN-622C [I.e. 3 units, but have to buy pairs]

I think you can do everything mentioned but apply FEC to Manual groups as mentioned above. You just adjust each manual power level as required (from the camera Flash Control Menu).

You can also purchase single units, there are some listed from other sellers on Ebay.

You cannot apply a Canon Ratio in Manual. You can apply a ratio by setting different power levels, but that is not as precise as what Canon does. It may well do for some jobs.

Do we know whether the YN-622C uses the muiltiple-exposure valuation technique, or the FEC/EV technique?

**UPDATE**

so I came home and tested out the on camera flash + off camera flashes. With my setup it's going to work perfectly.

5d 3 + yn622 + 580ex1
yn560 + yn622
yn565 + yn622
580exII + yn622

If you flip the 'mode' in camera to manual, it's going to flip the flashes that allow this (580ex2 and 565) into manual control and you can control them from camera, while leaving the 580ex1 in ETTL since that's all it knows (doesn't allow manual control). The 560 is still a dumb flash and just see's signal.

This is perfect for me b/c if I'm at a wedding where I dont want to have my "nice" flashes up I can put the 560's up, and still shoot with my on camera flash in ETTL and trigger the 560's across the room.

NOW. if you had ALL 580exII's or 565's, you'd have to put them in mix mode, which i haven't tested yet

Hey thanks for making that video, very helpful. Can you clarify something? In the vid you tested HSS using the 565 but i keep reading that HSS is coming with the new 568. What am I missing?

Clive,
You may want to rethink the "hyper sync" "super sync" idea and how it works.
The reason the monolight is fired early is so the peak power output is before the shutter is open. This permits the exposure from the strobe "tail" to light the subject as the slit moves across the sensor without a "bright" portion at the start. Monolights that use voltage for power control have longer tails i.e. longer flash duration as the power is reduced. Thus, a monolight at 1/4 has a longer and flatter tail than it does at full power. This is a benefit for "super sync" since it means less gradation across the exposure.

Speedlites, on the other hand, use a control circuit that cuts off power to the flash tube to control power. Thus, the only time there is a meaningful tail on a speedlite is at full power. At any power setting below full power the control circuit interrupts current to the flash tube, immediately quenching the flash. i.e. no tail. Thus, when using a speedlite for "super sync" the only time there is any contribution is at full power.

I've confirmed this with Einsteins (using the same quenching approach to power control) as well as YN-560 manual speedlites. I've also tested "hyper sync" with AB800s, Genesis 300Bs and Einsteins. Again confirming the behavior. There is a page on my tutorial website were I describe the tests with the Genesis monolights.

The bottom line is that "super sync" works within certain limits that are created by the camera and its pre-fire signal as well as the monolight and its flash duration and tail characteristics based on power setting.

Yes. At least to be able to describe briefly and accurately how the photog can use the 622s in "Supersync" mode. I'll PM you to take this stuff off-thread for now. Hope that's ok.

Basic specs, with edits.

CAMERA COMPATIBILITY
• Full control (Type A cameras)
Camera Flash Control menus. ETTL & FEC, Manual, HSS and SuperSync to 1/8000s, channels, groups, zoom
1D III, 1Ds III, 1D IV – compatibility confirmed. Advise reseller when ordering if required for these models. 5D II, 5D III, 7D

Did I miss something? Are there issues with the 5D II, 5D III, and 7D?

No, there is no issue with those models. They should be on the next line, not run on from the 1D line.

Edit: Thanks. New Line lost when colour text was added. Fixed.

Anyone that has unupdated versions and dont want to go thruthe hassle of sending them them backto interested in selling? Pm me.

I want to see some sample photos... YN622+AB+FF/CROP

I ordered 2 YN-622C's from ebay. Some seller was doing it for close to $83. I'll have them in a few weeks. I'll be using it with a YN-468II and a Canon T2i/550D. I'll let you know how it goes, but I expect it should go over well.
