Yongnuo 622s vs Canon RT

Hi all.

I've recently sold my Canon 430ex2 flash, and the only flash equpment I have is two YN-622C.

I'm thnking about a two-three flashes capable of HSS and TTL.

At the moment I can:
1. Grab a 622C-TX controller and cheapest TTL/HSS flashes(YN500?) - easiest solution. If I need to add another flash I need to get a 622transiever and flash.
2. Or sell my 622s' and get into canon rt system. Obviously get a YN-ST-E3 from Yongnuo and YN-600RT flashes. Cons are: I don't need extra transievers, I can use someone's else canon RT flashes. On the other side is price. YN-600RT cost more thne YN-500 and 622, but not too much.

I know about five groups instead of three. I know that distance might be different.

I wonder if there's anything else I'm missing? Should I pay more for Yongnuo RT system?

The YN-622C is a radio trigger system for the older Canon IR based ETTL system.
The YNSE3 and YN 600RT is their version of the newer Canon 600EX-RT ETTL system.
There are significant advantages to the newer technology. So, the first question you have to answer is whether you want to continue to invest in the older technology or invest in the newer technology.

Once that question is answered, the product choices are relatively straight forward.

Well, I know where 622 came from. And I know that RT is newer system.

But older 622 tech still doing it well for me:
622 TX have same Gr mode with ETTL correction for each group(ABC), can do a proportion between A:B and so on.

As both system will do the job, I really wanna see those advantages from a newer technology.

What advantages I can see:
-$50 more for each flash =)
-but YN-600RT are more powerful then YN-500
-Can borrow friends' 600RT and use it. (None of my friends have one, but anyways)
-5 groups instead of 3.
-No need in transiever.

Possible drawback of RT:
I can spend a $35 for extra 622 and be able to borrow any flash from my friends.

May be I'm missing something?

The YN622C-TX is apparently in the middle of a design upgrade to address limited range issues:

For those who purchased YN622C recently, we have added a YN560 mode to YN622C transceiver.

To enter this mode, hold down CH button and turn the device on. Then YN622C can receive commands from YN560-TX and update/trig the flash on it. The color of status LED is orange to indicate that YN560 mode is on.


And, we improved the PCB design of YN622C-TX and believe that it's as good as YN622C now.

If you opt to go that route you may want to wait until the old stock is depleted to ensure you receive the "improved" model with the new printed circuit board design. Mine has very limited range compared to my traditional 622C transceivers or my RT transmitter.

Yea, I read about it.

Is it an issue to you? I believe it can do 15-20 meters, I don't remember I ever need more then that.

RT system doesn't have such issues?

I have 3 speedlights based on the 622 system and if I were starting over, I'd go with the 600 system. I don't like the additional height added by the 622 and extra connection. The added height makes some modifiers difficult to use as they are usually designed for the height of the speedlight alone. Plus with the 600 system there are fewer 'parts and pieces' to store in my bag and lug around which means fewer batteries too.

I have 2 Canon 600's and 2 Yongnuo YN600EX-RT - they work exactly the same. Besides the Yongs being a free rotation system vs the push button of the canons, I can't tell the difference.

I would pay more and get the RT's, they are worth it

My 622-tx does a little over 30 feet (about 10 meters) definitely not 30 meters. So far it's not an issue to me but I'm really hoping it doesn't become one.

I have not heard of the rt system showing the same limited range issues as the 622-tx.

Were you planning on adding a studio strobe? is probably another question to ask yourself. Dead easy to add one in the 622 eco system; maybe not so much with RT at the moment (unless you like dumb optical slaving).

I guess nothing exists now (???) but surely Yongnuo will just make a 600-compatible receiver, won't they?

My YN622C-TX has a reliable unobstructed range of about 25 to 30 feet. It certainly is an issue. The same issue is not present in the traditional YN622 transceiver units or in my RT equipment.

My tests indicate 20M/66ft max range with the YN622C-TX, in the open.

The design engineer says that the C-TX circuit board has been re-designed, and now matches the 622C range. See https://photography-on-the.net …showthread.php?​p=17351025

I have ordered one of the new units through the OFFICIAL YN eBay shop, and am eagerly looking forward to it arriving for testing!

PS It's a hardware issue, not a firmware one.

this is exactly what i was thinking.

the hassle of dealing with adding a receiver (and additional batteries) to a flash is offset by being able to fire my CL-360 and potentially any other 'non-RT' speedlight or strobe.

+1 This is the reason I am currently using both 622 and RT transmitters depending on the flash units I'm using. If someone develops an RT compatible receiver I'll switch over to exclusive RT. Until that occurs I'll continue to use the older 622 system when mixing my 600's with other equipment.
