Yongnuo, the manufacturer, describe the YN-622N 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“.
Where do they fit into the market?
- Yongnuo YN-622N is more advanced than the Hähnel Tuff TTL, which does not give you control of manual power levels.
- YN-622N 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.
- YN-622N is less powerful than the Phottix Odin, since a smaller range of flashes and cameras are supported and the YN-622N doesn’t have its own LCD control panel.
- YN-622N is more practical than the RadioPopper PX, which is a bulky hack that only extends the range of an existing infrared system.
- YN-622N 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 YN622N relies:
- 1D Mark III, 1D Mark IV, 1Ds Mark III
- 5D Mark II, 5D Mark III
- 7D
- 40D, 50D, 60D
- 450D, 500D, 550D, 600D, 650D
- 1000D, 1100D
- 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.
How does wireless E-TTL ratio control work?
- Set the desired group – A, B or C – on each of your YN-622N 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-622N 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-622N 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-622N 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.
How does wireless manual control work?
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.
Is it possible to mix wireless manual flash and E-TTL in the same set-up?
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.
- Battery: 2 x AA batteries per transceiver (Not included in the package)
