Hey everyone! I finally pulled the trigger and upgraded to the Canon EOS 90D a few months back. I'm absolutely loving the 32.5MP sensor and how snappy the autofocus is for wildlife and sports, but I've run into a bit of a wall when it comes to indoor photography and event work.
The built-in pop-up flash is... well, it’s a built-in flash. It’s okay for a quick emergency fill, but it’s giving me those flat, harsh shadows and that dreaded red-eye that I’m trying to move away from. I’ve started taking on more indoor gigs lately—mostly small family reunions and some community theater rehearsals—and I’ve realized I desperately need a reliable external speedlite that I can bounce off the ceiling or walls to get a more natural look.
I’ve been doing some research, but the sheer number of options is making my head spin. I know Canon’s own Speedlite 600EX II-RT is considered the top-tier choice for this body, but at that price point, it’s a massive investment for someone who isn't a full-time pro yet. On the other hand, I see a ton of people recommending Godox, specifically the V1 with that round head or the V860III. My main worry is the communication between the camera and the flash. I really want a unit that integrates perfectly with the 90D’s internal menu system so I can adjust settings on the fly without struggling with tiny buttons on the back of the flash itself.
I definitely need something that supports E-TTL II for those fast-moving moments where I don't have time to dial in manual power. Also, High-Speed Sync (HSS) is a must-have for me because I plan on doing some outdoor portraits and want to keep my aperture wide open even in bright daylight without blowing out the sky.
So, for those of you who have been rocking the 90D for a while, what flash has given you the best results? Are the third-party options like Godox or Yongnuo reliable enough for consistent work, or should I just bite the bullet and save up for the official Canon Speedlites to avoid any compatibility quirks?

Ok so, I've actually had issues with cheap flashes failing mid-shoot which is SO frustrating... honestly ruins the vibe. If you wanna save cash, look at the Godox TT685II-C Flash for Canon for about $130. It supports HSS and E-TTL II, tho it wont feel as "pro" as the Canon. Its not as good as expected build-wise, but for the price, it works. Cheers!

Ok so, I went through this exact same thing last year when I started shooting local events with my 90D. I was sooo worried about third-party flashes not "talking" to the Canon menu system, but in my experience, it’s not as scary as it seems! Basically, you want that E-TTL to handle the math for you so you aren't guessing power levels mid-convo, and HSS is what lets you use those wide apertures outside without blowing everything out. Here is how my journey actually went down: 1. I started with a used Canon Speedlite 430EX III-RT for around $200. It integrates perfectly with the 90D menus, which was a huge relief cuz I hate fiddling with tiny buttons in the dark. 2. Later, I tried the Godox V860III-C Flash for Canon and was shocked that it also showed up in my camera settings menu. It's way cheaper than the flagship Canon stuff but feels just as snappy. 3. I found that having a Li-ion battery is literally a game changer. No more carrying 20 AA batteries in my bag, which saved me so much stress during long community theater gigs!! Honestly, the Godox V1-C Flash for Canon with that round head is what I use most now. It’s been super reliable for me and hasn't glitched out once! gl!

yo! Honestly, I totally get the struggle with that pop-up flash... it's literally the worst for event work lol. I spent forever researching this for my 90D and found these budget beasts: • Godox V860III-C Flash for Canon: Basically the best bang for your buck at $160. The lithium battery is a lifesaver!
• Godox V1-C Flash for Canon: That round head light is amazing for about $200. Tbh, they both sync perfectly with the 90D menu for HSS and E-TTL II. Save that cash!

I've been looking into this a lot lately too - basically trying to see if there's anything outside the big "G" brand that's worth it. I totally agree with the others that third-party is the way to go, especially since the 90D is so good at communicating with newer tech. From the research I’ve done, there are a couple of other brands that people seem to overlook: * Sigma EF-630 Electronic Flash: This one is a sleeper hit. It’s got a great interface and is really compatible with Canon's E-TTL II, plus it feels a bit more rugged than the super cheap stuff.
* Neewer NW670 Speedlite: If you are on a literal shoestring budget, these are everywhere. They might not be "pro" but they get the job done for basic fill light.
* Yongnuo YN685 II Speedlite for Canon: These have been around forever and are known for being really solid for the price, though the menus can be a bit clunky compared to Canon's own system. Tbh, I’m still a bit of a beginner with flash photography myself, but it seems like the gap between brands is closing fast. Does anyone know if the Sigma firmware updates are easy to do? That’s the only thing holding me back from pulling the trigger...

Hey there, just saw this. I've spent way too much time tinkering with DIY lighting rigs on my 90D, so I totally get the hesitation. Using a real speedlite is a massive jump from that pop-up, but you gotta be careful not to overbuy or underpower. To give a better suggestion, I have a couple questions:
- Are you planning on keeping the flash on the camera body 100% of the time, or do you want to eventually move it onto a stand with a wireless trigger for more creative stuff?
- How big are these theater spaces usually? Bouncing light is the way to go for sure, but you'll be surprised how fast you run out of juice if the ceilings are high or painted dark. Just make sure whatever you get has a decent recycle time, otherwise youll be standing there waiting while the best moments pass you by...

Late to the party but @Reply #4 - good point! I actually went through a phase where I tried to save money with those generic brands and it totally backfired on me during a friends birthday party. The flash just stopped talking to my camera halfway through and I felt like a total amateur... super embarrassing. Since I'm using a 90D now, Ive realized that reliability is way more important than saving fifty bucks. Basically, if you want everything to just work without thinking about it, here is what I've found:
- Stick with the Canon brand flashes for the most seamless menu integration.
- Some third-party brands are okay, but they sometimes have weird firmware quirks after a camera update.
- Official gear tends to hold its value way better if you ever decide to sell it. Honestly, just go with any of the official speedlites from Canon. You really cant go wrong with the first-party stuff because it was literally designed to speak the same language as your 90D sensor. Id rather spend a bit more now than worry about my flash failing when the cake is being cut... its just not worth the stress imo.
