YongNuo YN-622C/YN-622C-TX Controller Triggers 2

The main problem with the 420EX is that zoom follows the focal length and you can't manually control it.

I was reading in the unofficial user manual that the YN-622Cs with a build date of 12/2014 or later have a firmware update to accept commands from the YN-560TX.

My question is, I'm buying two that were bought from B&H this year and they don't have a build date in the battery compartment, only a serial number. Is there a way to look up Yongnuo' serial numbers?

That would suggest that the units have been opened for some reason.

Not to my knowledge. The only use that YongNuo seem to make of the serial number is to determine who in the world is responsible for service/support. Prices to distributors and dealers vary on how much liability they take over from YongNuo. It must be tempting to take full liability for end user service and get maximum margin, then not supply the service.

You can follow the procedure on page 26, and if the Status turns orange, it has the mode. If not, it is too early.

I'm a little concerned about the status indications on the YN622 vs. those described by Yongnuo and in the TOYUG. For example, my new units (3/2015 date code) behave as follows: When I hold CH SET down and power up the unit, the A and C1 lights blink 3 times and then when I let go of the CH SET button the power light comes on – red. Maybe it is supposed to be orange, but it's the same color as my older units... It's pretty clear that it's setting the YN560 compatibility mode but the indication is not as I expected. Using the same power up sequence on a 2014 unit causes no visible indication; the power light just comes on.

Interestingly, I don't get the power light blink when powering up the unit with low batteries either. The unit powers up seemingly normally, but then if it's a receiver, it starts triggering the attached flash at a 1 Hz rate and you have to turn it off to stop this behavior. I've had 2 separate units both do this, and the batteries were clearly below recommended voltage - replacing them solved the issue.

I'm going to try my new YN622C-TX tonight (it's a 4/2015 date code with the latest FW) to see how it works with the 7D mk II.

Yongnuo very carefully position the Date of Manufacture label over the 5th case screw within the battery compartment. I've heard mention of this being removed and placed elsewhere but have never managed it myself - they're quite delicate and certainly absence would most strongly suggest that the cases have been opened. You can't open the case up without virtually destroying the label - I'd surmise that this is kind of the point of it's position

Oh I see, yeah I bought two from somebody that told me he never got to used them. While we were talking about it he sent me pictures and mentioned that the it looked like a sticker was pushed all the way down.

I meant that the YN-622C were updated after 12/2014 by the factory and shipped that way.

I'm getting YN-622C on Saturday so I'll be able to check if they have the newest firmware or not.

Thank you both for the help!

Incidentally, sometimes the QC person is not very careful and the sticker is poorly attached; I was able to lift a couple of mine using an X-Acto knife without damaging them. Of course I am not re-selling mine, I just wanted to keep the sticker intact for reference.

Thanks for sharing this information this is great to know. I immediately opened my 6 units that i had bought in a 4 pack, 1pack and the CTX to find out that all are dated to 2014 with in months of each other and no sign of tampering...

I would second the Flashpoint RL600 idea. Having said that, I have Godox 860's. They are terrific! They have the NiCAD rechargeable battery paks that are advertised to shoot 500+ full power pops per charge. I cannot confirm the exact count, but I have never had them run low. Only once did I see the battery level indicator register less than full charge, and that was a long session which was probably 250+ pops. It has a guide number of 58, and has all the features of the top speedlights (HSS, Sec Curt, TTL, etc), and are very well made with a high quality feel to them.

Have you used the 860's with the 622c triggers? I am considering getting a couple for weddings but would like to confirm they work with the triggers I use. Also, the Neewer 860s are the same, right?

I have used four Godox 860's, all with the 622Cs, and the 622C-TX on camera. I also had a 430 EXII as the 5th light. All worked great together.

I am almost certain the Neewer 860's are the same product, but I'm not an expert. One thing I have discovered is that depending on who you pick as the supplier (I use Amazon, and there is often a choice), some ship quickly (obviously kept in stock in the US) while others ship from Hong Kong. If you have a fairly quick need, you need to watch that. It is usually worth paying the few bucks more for rapid delivery. Sometimes the lowest quoted price is not the best deal if you save $4, but wait 6 weeks.

Thanks for the reply. I have two yn568ex ii, but the battery life on these units has me intrigued and think it would be great for what I'd use them.

I use Amazon Prime so I usually go that route for purchases. Saves a lot of hassles.

Yeah, me too. Each one comes with the battery and a charger, so you wind up with plenty of chargers. You can buy additional batteries (I think they are Neewer brand) in case you think you'll need more that 500 pops per flash and want to have spare power at the ready. I guess that's the only down side, that the batteries are very good, but are unique to the flashes. You can't just send the bride's nephew out to the store to buy more AA's if you are using more flash than you had planned.

I plan to purchase two with a spare for each. If I go through those, I have two yn568exii and two yn560ii. One way or another I'll get it covered.

I got mine today and this is exactly what happens. The light comes red as well. I'm getting the YN568 II and two YN560 IV next week. I'll test this whole compatibility thing then.

Glad I'm not the only one seeing this!
