Just catching up on this thread and wow, so much good info here! I remember when I first started out I spent a fortune on native gear before realizing that for 6+ hour events, the technical specs on some of the lithium-ion third-party units are actually insane for the price. I've been using a budget-friendly setup for three years now and the reliability has been fantastic!!

• Godox V860III-C gives you like 480 full power shots which is amazing for long weddings.
• Yongnuo YN685 II for Canon is a total steal and the built-in wireless is super snappy.
• Westcott FJ80 II Speedlight has a 1.5s recycle time which is just incredible for the money. Honestly, saving that cash allowed me to grab a better prime lens which made a huge difference in my portrait work. Love helping out fellow R5II users so if you need any more specific data on the battery discharge rates or thermal performance tests I did, just ask! Good luck with the new kit, you're gonna love it.

I suggest you get the Godox Flashes, they are cheap but powerful. Such as Godox V1Pro.

Facts.

I totally agree with the sentiment that native is the way to go for this specific body. Basically, when you're spending that kind of money on an R5II, you really want the flash and camera to speak the same language without any weird translation issues. Tbh, looking at the current market, it really comes down to whether you prioritize the 'it just works' factor of the first-party ecosystem versus the modularity of the big third-party lighting systems. From a market research perspective, here’s how I see the landscape right now: * **Native Canon Gear:** You’re paying a premium for that deep integration, especially with the new digital shoe pins, but the reliability in the heat of an event is unmatched.
* **Premium Third-Party Brands:** Go with any of the high-end European lighting brands if ur looking for that perfect color consistency across ur whole kit.
* **Value-Driven Brands:** These are great if you need to buy multiple units for the price of one, but sometimes the build quality doesn't hold up to 6+ hour grinds. Honestly, if reliability is ur top priority for events, just stick with the official Canon lineup. I've seen too many third-party triggers flake out during a wedding ceremony to trust my career to anything else.

I am literally having this exact same issue right now. Been shooting professionally for years and honestly the transition to the R5II has me totally stumped on the flash front. I have been digging through threads for weeks and still cant find a definitive answer that makes me feel confident about pulling the trigger.

• Stuck between staying native or switching systems entirely
• Nervous about those new shoe pins being a bit more delicate for heavy use
• Really need to know what survives a 10 hour event without constant overheating Its honestly so frustrating because I am usually the guy who can rig up or DIY any gear solution, but this time I am just as lost as you are... I have been dealing with this for a month and still got nothing.

I'd go straight to the Canon Speedlite EL-5 - it's frankly the flash the EOS R5 Mark II was born to work with. Designed specifically for Canon's Multi-Function Shoe, it offers seamless communication and power delivery directly through the mount.

Just wanted to say thanks for everyone chiming in. Super helpful discussion.

> Christopher: "Basically, when you're spending that kind of money on an R5II, you really want the flash and camera to speak the same language without any weird translation issues." I totally agree with Christopher on this. In my experience over the years, I've tried many different setups, and honestly, performance under pressure is the only thing that matters. I used to be all about saving a few bucks with off-brand stuff, but after a few missed shots at a high-end event because of a sync glitch, I shifted my focus back to native gear. One thing I've noticed is that the TTL consistency is just way more predictable when you're using hardware built specifically for that mount. It is that extra layer of safety that lets me actually enjoy the shoot instead of constantly checking my LCD to make sure the flash fired correctly... definitely something to think about if you're doing 6+ hour gigs. Plus, the weather sealing integration between the body and a native unit is a huge peace of mind factor if you're shooting outdoors.

I have to say, the current state of flash compatibility for the R5 Mark II is frankly disappointing for those of us who have been in the game a long time. It is not as good as expected, and the technical hurdles with the new shoe design are quite frustrating to navigate.

• Honestly, just go to the official manufacturer website and download their compatibility PDF; it covers the electronic pin constraints better than any forum post will.
• You should search YouTube for the latest R5II flash sync tests because there is a great video that breaks down the recycle times and heat issues.
• Check the professional photography subreddits where people are documenting the shoe connection failures. I saw a really comprehensive guide on this exact topic a few days ago, so just google it and you will find it pretty easily. It is better to get the data straight from the technical specs than to rely on anecdotal stuff here.

^ This. Also, I've been around the block a few times and seen tech shifts like this before. The R5II shoe is definitely proving to be a headache for some. Before I weigh in with a specific path, I need to clear a few things up:

• Do you usually stick to on-camera bounce or are you running a full wireless rig with triggers for these portraits?
• How much does the physical balance of the camera matter to you during those 6-hour stretches? I'm not entirely sure, but I think I heard that some of the older high-end studio brands are having issues with the new shoe pins. IIRC, someone mentioned the connection being super sensitive to any side-to-side wobble which might cause the camera to lock up. Not sure if it's just a mounting issue or something deeper with the electronic handshake, but it's worth being cautious. Honestly, looking at more modular portable systems instead of just standard speedlites might be the play here if you're doing heavy event work.
