Hey everyone! I finally made the leap from my trusty 5D Mark IV over to the Canon mirrorless ecosystem with an EOS R6 Mark II. While I am absolutely blown away by the autofocus and the image quality, I’ve hit a bit of a roadblock when it comes to my lighting setup. My older Speedlite 600EX-RT feels incredibly front-heavy on the smaller R6 body, and I’ve noticed some occasional communication hiccups when using my old triggers through the adapter.
I’m looking to invest in a new external flash that feels 'at home' on a mirrorless body. I primarily shoot wedding receptions and local events, so having reliable E-TTL II performance is a must for me—I simply don't have the time to fiddle with manual settings when the dance floor gets busy. I've been eyeing the Canon Speedlite EL-5 since it’s specifically designed for the new multi-function shoe, but I’m a bit hesitant about the price and the fact that it requires the newer shoe design, which might limit me if I ever use it as a slave on an older body.
On the flip side, I keep seeing the Godox V1 and the V860III mentioned everywhere. The round head on the V1 looks great for a softer light falloff, and the lithium-ion battery life is super tempting for long shoot days. However, I’ve heard some mixed reviews about how third-party flashes handle the AF-assist beam on mirrorless sensors, as I know the traditional red grid doesn't always work the same way it did on DSLRs.
Since mirrorless cameras handle exposure preview and autofocus differently, I want to make sure I get something that integrates seamlessly without causing any lag or overheating during a burst of shots. I’m trying to keep the budget around $300 to $500, but I’d be willing to save up more if a native Canon flash is truly the superior choice for the R system long-term.
For those of you who have switched to the R5, R6, or R7, which flash are you currently using as your go-to on-camera light? Do you find that third-party options like Godox play nice with the Canon R-series communication, or should I just bite the bullet and stick with the native EL series for the best reliability?

Respectfully, I'd consider another option before jumping on the Godox train for pro work. I've been shooting weddings with the Canon EOS R6 Mark II for a while now, and honestly, third-party flashes like the Godox V1-C Flash for Canon still struggle with that AF-assist beam—it basically doesnt work because the red grid is designed for DSLR phase-detect sensors, not mirrorless. You'll find yourself hunting for focus in dark reception halls which is a total nightmare, you know? So yeah, my quick tip: if you need reliability, bite the bullet on the Canon Speedlite EL-5. Since it uses the new multi-function shoe with those extra gold pins, it’s a direct digital connection. No more communication hiccups like you're seeing with adapters. Plus, the weather sealing and recycle times are way better than the old Canon Speedlite 600EX-RT II. It’s pricier, but for events, it works well. GL!

> I’m trying to keep the budget around $300 to $500 For ur situation, I'd basically just grab the Godox V1-C Flash for Canon. It's way cheaper than the EL-5 at around $260 and honestly feels sooo much better balanced on my R6... works well!

So yeah, I totally get the weight issue!! When I first moved to the R system, I tried to force my old setup to work with adapters and it was honestly a mess. I spent way too much time researching the technical specs of the new multi-function shoe and unfortunately... it's kinda a black box for third-party companies. The main thing to realize is that mirrorless sensors use a different frequency for AF-assist, so those old red grids basically do nothing now. I tried a few of the popular third-party alternatives and while the battery life was insane, the communication lag during high-speed bursts was super frustrating. Like, I’d press the shutter and the flash would just... think about it for a second?? It’s literally the worst feeling at a wedding. In my experience, the native brand flashes handle the heat dissipation and E-TTL math way better. It sucks that the price is so high, but the integration with the camera’s internal menu is just miles ahead of the reverse-engineered stuff. I ended up trading in my old gear for the native mirrorless-specific one and the balance is way better. Honestly, just save up for the native setup, its worth the peace of mind!!
