Hey everyone! I’ve been using my Canon EOS 5D Mark III for a few years now, and while it’s still an absolute workhorse for my photography, I’m finally hitting a wall where I really need a dedicated flash. Since the 5D3 doesn't have a built-in pop-up flash, I’ve been relying entirely on fast glass and natural light, but that’s getting really tricky for indoor events and late-evening portraits.
I’ve looked into the official Canon Speedlites, but honestly, the prices for brand new units like the 600EX-RT II are just way out of my current budget. I’m hoping to find something reliable in the $100 to $175 range that won't feel like a cheap plastic toy. I definitely need something that supports E-TTL for quick adjustments during candid moments and High-Speed Sync (HSS) so I can use it for fill light during bright outdoor shoots without being limited by the 1/200 sync speed.
I’ve heard a lot of buzz about third-party brands like Godox and Yongnuo lately, but I’m a bit nervous about build quality and how well they communicate with an older body like the 5D Mark III. Does anyone have a specific "bang for your buck" recommendation that balances power and recycling speed? Should I stick with a used Canon 430EX or go for a newer third-party option?

Sooo i actually spent years overpaying for Canon gear before I finally tried third-party stuff. For your 5D3, I'd seriously recommend the Godox TT685II-C Flash for Canon. It's about $130 and honestly feels super solid, not like a toy at all. It handles HSS and E-TTL perfectly for those fast-paced indoor events. Way better value than an old Canon Speedlite 430EX II or overpaying for a new 600EX-RT II lol

Curious about one thing: are you mostly keeping the flash on-camera or going off-camera later? Ngl, I've had issues with third-party mounts getting loose on the 5D3 hot shoe, which basically ruins the E-TTL connection mid-shoot. Its super frustrating. If you can stretch your budget, the Godox V860III-C Speedlite for Canon is a beast cuz of the lithium battery, but lmk your setup first!

Quick question—are you shooting handheld? I agree Godox is the play. * Godox: Great features
* Yongnuo: Honestly pretty buggy Unfortunately, I’ve had issues with mount durability on the 5D3 tho. Good luck!

Adding my two cents here because I have been down this road. I used to be a total brand snob until I realized I could buy three third-party flashes for the price of one official one. But be careful... I once had a budget unit literally melt its own battery compartment during a long portrait session because the heat management just was not there. Before you pull the trigger, I gotta ask: are you planning on doing a lot of rapid-fire shooting or burst modes during these events? My experience with the cheaper brands taught me a few things:
- Third-party mounts can be slightly loose, which makes the E-TTL connection flick on and off if you move the camera too fast.
- The recycle beep on some of the cheaper ones is loud enough to actually annoy people at a quiet event.
- You might find that the color temperature shifts a bit more on the budget brands compared to the consistency of the original gear. I would suggest looking closely at the locking mechanism on whatever you buy. Some use a screw-down ring that is a total pain, while others have the quick-flip lever that fits the 5D3 way better. It makes a huge difference when you are rushing to swap gear mid-shoot.
