Yongnuo YN622C-TX Compatibility with Canon EOS RP?
Yongnuo YN622C-TX and YN622C II work on Canon 1300D but fail ETTL on EOS RP due to hotshoe protocol changes. Fix with Godox XPro-C for full ETTL, HSS, and remote control on Canon mirrorless.
Is the Yongnuo YN622C-TX and YN622C II compatible with Canon EOS RP cameras? These synchronizers worked perfectly with Canon 1300D (including ETTL mode with Yongnuo YN560 IV flash, even though the flash lacks built-in ETTL), but on the Canon RP, ETTL doesn’t function, and flash power adjustment is only possible directly on the flash in manual mode—not via the on-camera transmitter. Other modes don’t work with the synchronizer. Is this a compatibility issue with specific camera models, and how can it be resolved?
The Yongnuo YN622C-TX and YN622C II flash triggers show limited compatibility with Canon EOS RP mirrorless cameras, unlike their reliable performance on DSLRs like the Canon 1300D where ETTL works seamlessly even with flashes like the YN560 IV. On the RP, ETTL fails, remote power adjustment via the transmitter doesn’t function, and you’re stuck tweaking settings directly on the flash in manual mode only—this stems from Canon’s updated hotshoe protocol on R-series bodies blocking non-native third-party control. The fix? Switch to modern Godox synchronizers like the XPro-C, which deliver full ETTL, HSS, and remote adjustments on the EOS RP.

Canon EOS RP Yongnuo YN622C-TX Compatibility Issues
Ever tried mounting your trusty Yongnuo YN622C-TX on a Canon EOS RP, only to watch ETTL blink out and remote controls go dead? You’re not alone. These triggers, designed primarily for older Canon DSLRs, hit a wall with the RP’s mirrorless hotshoe. The RP demands stricter communication protocols that the YN622C series just can’t fully handshake with.
What happens? Basic firing might work in manual mode, but forget ETTL metering or tweaking power, zoom, or groups from the camera menu or transmitter. It’s like the RP locks out third-party tweaks to protect its ecosystem. This isn’t a faulty unit—it’s a deliberate shift by Canon starting with the EOS R lineup.
And yeah, that YN560 IV flash pulling ETTL through the 1300D? Magic on DSLRs, but the RP says no thanks. Hotshoe pins changed subtly, protocols evolved, and boom—compatibility crumbles.
Why It Works on Canon 1300D but Fails on RP
Picture this: Your Canon 1300D (a solid entry-level DSLR) plays nice with the Yongnuo YN622C-TX because it sticks to the classic ETTL II protocol from the DSLR era. Mount the TX on top, slap a YN622C II on the YN560 IV off-camera, and ETTL meters exposures perfectly—even though that flash is manual-native. Why? The 1300D’s hotshoe speaks the old language fluently.
Flip to the EOS RP. Canon’s R-series mirrorless cameras revamped the hotshoe for better integration with their RT system (think EL-1 or 600EX-RT). It’s still physically compatible—no adapters needed—but the digital chatter? Totally different. The RP often ignores or partially supports non-Canon triggers, blocking menu access for flash settings.
Users on Reddit’s Canon forum nail it: “The camera does not allow flash menu settings with non-Canon units mounted.” Spot on for the RP too. It’s model-specific—DSLRs yes, R-series mostly no.
Short and punchy: Protocol mismatch. DSLR legacy vs. mirrorless future.
User Reports and Common Problems
Scour the forums, and the stories stack up. On DPReview, EOS R users (close cousin to RP) report the YN622C-TX firing inconsistently in manual, with ETTL dead. One fix? Swap the TX for a transceiver—but even then, camera menu control is your only option, no remote tweaks.
Reddit threads for Canon R7 echo this: Intermittent manual triggering on R bodies, ETTL sometimes flickering through. But power adjustment? Nope, head to the flash itself.
Canon Community posts highlight similar gripes with 430EX flashes: ETTL okays, but manual intensity and zoom refuse transmitter commands. For RP owners, it’s the same script. Other modes like multi or HSS? Forget it without native support.
Why the inconsistency? Firmware variances, channel glitches, or just the RP enforcing “Canon-only” vibes. Frustrating, right?
Firmware Updates and Workarounds
Hoping for a Yongnuo firmware savior? Check Yongnuo Rumors—they push updates, like v1.10 for YN622C-TX improving YN685 comms. But R-series fixes? Crickets. Most target DSLRs or specific flashes, not EOS RP hotshoes.
Troubleshoot first:
- Power sequence: Camera on, then TX, receiver, flash.
- Match channels/groups exactly.
- Test ETTL on-camera first.
Partial hack from DPReview: Use YN622C transceiver as master instead of TX. Gets TTL/manual/multi reacting, but camera menu only—no transmitter dials. Meh for off-camera workflows.
Bottom line: Band-aids, not cures. If you’re deep in Yongnuo, it might limp along in manual. But for ETTL reliability? Time to upgrade.
Best Godox Synchronizers for Canon EOS RP
Godox to the rescue—community favorite for Canon EOS RP flash synchronizers. Their 2.4GHz X-system crushes it with full ETTL, HSS (1/8000s), remote power/zoom, and groups.
Top picks:
- XPro-C Trigger: Affordable ($70), intuitive screen, 5 groups. Pairs with any Godox X-flash.
- Godox V1C or V860III-C: On-camera speedlites doubling as masters. Full TTL on RP, fast recycle.
- TT685II-C: Budget off-camera beast ($110), HSS-ready.
Reddit users rave: “Godox 685C works off-camera perfectly on RP.” Same for R2 Pro II-C transmitter.
Sell your YN622 gear, grab Godox—your RP will thank you. Bonus: Cross-compatible ecosystem.
Canon Native Options
Want zero headaches? Canon’s RT lineup shines on EOS RP.
- ST-E3-RT Mark II: Compact transmitter, full ETTL/HSS.
- 430EX-III RT or EL-1: Speedlites with radio mastery.
DPReview suggests refurbished 430EX—$209, perfect match. No third-party drama.
It’s pricier, but bulletproof. Mix with Godox via optical if needed, though radio’s king.

Conclusion
Yongnuo YN622C-TX compatibility with Canon EOS RP boils down to a no-go for full ETTL and remote control—great on 1300D DSLRs, but R-series mirrorless demands better. Ditch the headaches with Godox XPro-C or V1C for seamless synchronizer performance, or stick Canon RT for purity. Test in-store if possible; your off-camera flashes deserve reliability.
