YongNuo have two great 2.4GHz flash and trigger systems on the way with the new flagship YN-622 TX, TTL and HSS enabled transmitter due next month, and the YN-560 TX remote manual transmitter to arrive a month or so later.
But as promising as these 2 systems are looking, YongNuo have confirmed they will have no direct compatibility with each other. So you will effectively have to choose one system or the other, and stick with that. Or start looking at workarounds to somehow cobble the two systems together again (as we know many people will try to do). Which is frustrating, because that really just shouldn’t be necessary.
So there are basically two separate lines of triggers and compatible flash -
- Manual / Remote Manual - YN-560 TX, RF-603 II, RF-603, RF-602 – Compatible with the YN-560 III flash unit with built in remote manual receiver.
- TTL / HSS / Remote Manual - YN-622 TX, YN-622 transceivers – Compatible with TTL flash units like YongNuo EX flashes, and compatible Canon/Nikon TTL flashes.
Manual / Remote Manual
The manual line of triggers are compatible with the recent YN-560 III flash unit, which has a very convenient radio receiver built in, and the coming YN-560 TX transmitter which will enable remote manual power control with that YN-560 III flash unit.
(Please note, the transmitter images are currently just photoshop examples of what may be expected)
TTL – HSS – Remote Manual
Then there are the YN-622 line of TTL and HSS enabled triggers, which also offer remote manual power control, but only with compatible TTL enabled flash units mounted on YN-622 receivers. No other YongNuo radio triggers are directly compatible, except for the coming flagship YN-622 TX transmitter unit.
The new YN-622 TX transmitter due next month should allow easy TTL and remote manual power level directly through the simple built in LCD screen interface. But only with TTL flashes, and not the YN-560 III flash above (with built in remote manual radio receiver built in).
So the problem comes if you want to mix in YN-560 III flash units, when using the YN-622 transmitters and receivers.
Currently you can place an extra RF-602 transmitter on top of the YN-622 pass through hotshoe, to at least fire the YN-560 III built in receiver. But we know there is no pass through hotshoe on the coming YN-622 TX, so you won’t be able to do that work with the new YN-622 TX.
So at best this will mean trying to jerry-rig a second receiver to the camera’s PC sync port, (or possibly to the new transmitter if that possibly has a PC sync out).
Otherwise you could purchase YN-622 receivers for each YN-560 III flash. But that seems just a little ridiculous when the flash already has a more convenient radio receiver built in, and the YN-622 is still not going to be compatible with the remote power control.
This situation has come up (at least to some degree) due to YongNuo trying to support previous RF-602 and RF-603 owners by taking the YN-560 III down that compatibility route.
The question is where should it go from here now? YongNuo say these are two separate lines of triggers that won’t be compatible due to history reasons. But its very obvious in the near future most other companies will have nicely integrated remote manual and TTL systems. Triopo where actually the first to announce theirs months ago.
As mentioned a while ago in the YN-560 III review, one of the most common questions I get is are the YN-560 III compatible with the YN-622? So surely YongNuo also already had to see this issue coming.
It may be a big call, but personally I think if there is no practical way to add YN-560 III support to the YN-622 TX, YongNuo should just bite the bullet now and move YN-560 III compatibility to the YN-622 system rather than RF-602/3 support (call that the YN-660 III for now). Maybe they can offer both, but do it now so people know which remote manual flashes to buy into.
The two systems are not going to go away though, so a dual transmitter catering for both receivers may still be the best way to integrate them. I thought there was a good chance YongNuo would have already catered for this in the coming YN-622 TX, but obviously not.
So have YongNuo missed the priority here again? Would you prefer RF-603 compatibility or YN-622 TX compatibility with the YN-560 III flash if it came down to that?
In an ideal world people would just use one system or the other, but that’s just not going to happen. Both systems are going to be extremely popular, and people will be rigging their own dual transmitter, and cursing YongNuo for making their life difficult. YongNuo need to get this show on the compatibility road as soon as possible.
