Everything you need to know about the Yongnuo YN-622
Since the announcement of the Yongnuo YN-622C E-TTL radio triggers, lots of people have been asking questions. These will be complex devices and it is easy to get confused about their capabilities. We’ve got a direct line to the developers, a copy of the instruction manual and will be getting hands-on soon. In the meantime, here is a Q&A to help you out. Anything we miss or don’t make clear, let us know in the comments.

Yongnuo, the manufacturer, describe the YN-622C system as “high performance master and slave equipment for multiple flash photography”. It is based on a two-way transmitter-receiver that allows one camera to control multiple flashes at the same time. It runs on 2.4GHz radio with 7 channels and 3 groups (A, B, C).
External flash functions include TTL ratio control, manual selection of flash group power output and high speed sync up to 1/8000s. TTL, Manual and Multi modes are supported. You can also install an E-TTL flash on top of the transmitter, known as “TTL pass-through“.
- The Yongnuo YN-622C is more advanced than the Hähnel Tuff TTL, which does not give you control of manual power levels.
- The YN-622C is more capable than the Pixel King, which does not have TTL ratio control or let you have multiple groups at different power levels. However, there are models of the King for Nikon and for Sony.
- The YN-622C is less powerful than the Phottix Odin, since a smaller range of flashes and cameras are supported and the YN-622C doesn’t have its own LCD control panel.
- The YN-622C is more practical than the RadioPopper PX, which is a bulky hack that only extends the range of an existing infrared system.
- The YN-622C will almost certainly be cheaper than the PocketWizard FlexTT5, which is an industry leader. While the FlexTT5 is much more advanced on paper, some photographers have to put a sock on their flashes for it to work reliably in practice due to radio interference. This is unlikely to be the case for the 2.4GHz YN-622.
These Canon EOS cameras have Flash Control menus on which the Yongnuo YN622C relies:
- 1D Mark III, 1D Mark IV, 1Ds Mark III
- 5D Mark II, 5D Mark III
- 40D, 50D, 60D
- 450D, 500D, 550D, 600D, 650D
- 1000D, 1100D
The following flashes will “support wireless remote control through camera menu”:
- Canon 600EX, 600EX-RT, 580EX II, 430EX II, 320EX, 270EX II
- YongNuo YN-565EX, YN468, YN468 II, YN467, YN467 II, YN465
If you use the Canon Speedlite 430EX or 580EX (not mark II) or an older camera without the Flash Control menu then you will have to make settings by hand. Older cameras that don’t have the same Flash Control menu include the original 5D, 10D, 20D, 30D, 300D, 350D, 1D and 1D Mark II.
- Set the desired group – A, B or C – on each of your YN-622C transceivers
- On your Canon EOS DSLR, hit [Menu] > Flash control > External flash func. setting > Wireless func. > Enable.
- If you have a flash on top of your on-camera YN-622C unit, select Master flash > Enable if you want it to fire, otherwise it won’t. It will behave like an off-camera flash in group A.
- In the External flash func. setting > Channel menu, pick your channel (1-4). The YN-622C transceivers can actually be set to more channels than the menu supports. To pick channels 5, 6 or 7, select it directly using the buttons on the on-camera YN-622C transceiver.
- Pick your ratio control mode from the External flash func. setting > Firing group menu. You have the choice of All (A+B+C), A:B or A:B C. In “All”, there are no ratios and each flash fires at the same power level (this is the same as having ‘Wireless func.’ disabled). In the other modes you can select ratios from 8:1 to 1:8 for the groups in 1/2-stop increments. Check your camera user manual for more details.
The set-up is similar to E-TTL ratios, but in External flash func. setting > Flash mode you pick “Manual” instead of “E-TTL II”. You will then be able to set each of your independent flash groups – A, B or C – to manual power levels from 1/1 to 1/128.
Yes. Yongnuo has a feature called “Mix Mode”. Hold down the [CH SET] button on the transmitter (the transceiver on your camera) for 3 seconds and Mix Mode will be enabled. If you have a flash on-camera, it will be fixed to E-TTL mode. For your off-camera flashes, set them up individually with their own control panels.
Yes, it is enabled by default. If your flash doesn’t support HSS then the maximum sync speed is 1/250s or less, depending on your camera.
There is also a mode called ‘Super Sync’ for manual flashes with long durations (e.g. studio heads). Set your camera to HSS mode and plug the flash into the receiver’s PC sync port. Yongnuo warns that Super Sync results may vary depending on your camera and flash combination.
Yes, you can select it from the Flash control menu. But it won’t work in Wireless control mode, according to Yongnuo.
No. If your flashgun has a high triggering voltage and you connect it to a Yongnuo YN-622C then you risk damaging the transceiver.
The Yongnuo development team are still considering making a Nikon version and assessing how to make it “different/competitive”. Indications suggest it will be a long way off, if the company even decide to make it at all.
The YN-622C is being released to the domestic market before it is available internationally, hence why the company said it would be released this month and you haven’t seen anything yet. With luck, it will be released for export this August. Keep an eye on the official Yongnuo store.
As for cost, we haven’t been given firm figures so you’ll have to wait and see. But I’d expect a price point somewhere between the $130 Pixel King and the $330 Phottix Odin. Obviously we hope it’s lower, so long as the manufacturer hasn’t cut corners to get there.
Yes. Stay tuned!
