If you bought the Canon EOS R100 because it gives you a lot of camera without spending a fortune, putting a $300–$400 flash on top of it probably isn't what you had in mind.
But going too cheap creates a different problem. A basic flash may give you more light, yet leave you fighting harsh faces, slow recycling, missed shots, or a system you'll want to replace as soon as you start taking photography more seriously.
That's why the sweet spot for the R100 isn't simply the cheapest Canon-compatible flash. It's finding one that gives you noticeably better indoor photos, portraits, family shots, and bounce flash without making your lighting setup feel more expensive than your camera.
I narrowed this guide down to five flashes that make sense at different stages: from an inexpensive first speedlight to more capable options you can keep using if you eventually move beyond the R100.
If you just want the short answer: you probably don't need the most expensive flash in this list. The better buy is the one that fixes what your R100's small built-in flash can't do while leaving enough room in your budget for the gear that will actually improve your photography.
Quick Comparison: Best Flashes for Canon R100
You don't need to study every flash specification to make the right choice. Start with how you'll actually use your Canon R100, then choose the flash below that matches that job.
Quickest decision: start with the Godox TT685II-C if you're unsure. It gives the R100 owner the important upgrades, more flash power, TTL, HSS, bounce control and wireless expansion, without immediately moving into a much more expensive lighting setup. Choose one of the other four when its specific advantage solves a problem you already know you have.
My Pick for Most Canon R100 Owners
The Godox TT685II-C is my first recommendation for most Canon EOS R100 owners because it puts the money into the parts of a flash that can actually change your photos: GN60 output, Canon E-TTL II, high-speed sync, a flexible bounce head, and wireless expansion.
That matters on a camera like the R100. You can spend considerably more on a speedlight, but the question isn't whether a more expensive flash has better specifications. It's whether those extras will improve the photographs you plan to take enough to justify putting that much money into an entry-level camera setup. The same logic applies to storage: a fast 128GB SD card for your Canon R100 like the SanDisk Extreme PRO UHS-I gives you U3/V30 performance and plenty of space for photos and video without paying for a much more expensive card standard your setup may not need.
The TT685II-C hits a useful middle point. E-TTL can handle flash exposure when you're working quickly, while HSS up to 1/8000s gives you more freedom when you want flash outdoors without being locked to a slow shutter speed. Its 20–200mm zoom range also lets the flash coverage change with the type of shot rather than throwing the same spread of light everywhere.
Where the TT685II-C Earns Its Place
The biggest upgrade over simply adding more light is control over where that light goes. The head can tilt from approximately -7° to 120° and rotate through 330°, so indoors you can aim it toward a suitable ceiling or wall instead of firing every shot directly into someone's face. Pair that softer bounced light with a Canon RF 50mm f/1.8 portrait lens, and you also gain a wide f/1.8 aperture for separating your subject from the background when you want portraits to look less like basic snapshots.
That makes it much easier to move beyond the hard, obvious look associated with small direct flashes. For family photos, indoor portraits, parties and everyday photography, learning how to bounce this flash can be more valuable than buying a much more expensive unit and continuing to point it straight forward.
There's room to grow too. The built-in Godox 2.4GHz X system can work as both transmitter and receiver, so buying the TT685II-C doesn't lock you into using it on top of the R100 forever. If you later start experimenting with off-camera lighting, additional Godox flashes or a compatible trigger can turn the first flash you bought into part of a larger setup.
Why I Wouldn't Automatically Spend More
The V860III-C and V1-C are tempting upgrades, but their advantages solve more specific problems. The V860III-C makes more sense when you're shooting enough frames that lithium power and faster recycling become important. The V1-C becomes more interesting when portraits and modifier-based lighting are a priority. If neither problem is holding you back yet, part of that upgrade budget may be better spent on something you'll use differently, such as the Canon R100 tripod grip with wireless remote for handheld video, remote shooting and a quick tabletop setup.
For occasional portraits, family photography and learning flash on the R100, you may be paying extra for convenience before you actually need it. The TT685II-C already gives you the core lighting tools needed to learn TTL, manual flash, bounce lighting, HSS and eventually off-camera flash.
There is a tradeoff: this isn't the choice I'd make for someone regularly firing through long, demanding sessions. The listing gives a recycle range of approximately 0.1–2.6 seconds, and one buyer comparing it with another workhorse flash reported slower recycling as the Godox was pushed hard. That's where stepping up to a lithium-powered model starts making practical sense.
At the other end, if your priority is simply getting something small and inexpensive onto the R100, the TT350C deserves consideration. It gives up power and endurance, but its compact body can be a better physical match for someone who specifically bought the R100 to keep photography simple. That same approach makes a spare Canon LP-E17 battery for the R100 a practical addition: it adds almost nothing to the size of your kit, but gives you another charged battery to swap in when a longer day of shooting outlasts the first one.
For everyone in the middle, the TT685II-C is the one I'd start with. You're getting enough power and control to make flash photography worth learning, while avoiding the easy trap of spending almost as much on the speedlight as you did getting into the R100 system in the first place.
When You Shoot Enough to Hate Waiting on Batteries
The Godox V860III-C starts making more sense than the TT685II-C when your problem isn't getting enough flash features, it's keeping those features ready through a longer shoot. Its rechargeable lithium battery is rated for around 480 full-power flashes, with recycling as fast as 0.01–1.5 seconds.
That changes the buying equation for event photography, repeated portraits, parties, or any situation where you're taking many flash-assisted photos in one session. Instead of building your workflow around sets of AA batteries, the V860III-C gives you a dedicated rechargeable battery and charger in the kit. And if you're moving to the R100 from an older Canon DSLR, a Canon EF-to-RF adapter for your existing lenses lets you bring compatible EF and EF-S glass into the same setup instead of rebuilding your lens collection from scratch.
You aren't giving up the important creative controls to get that endurance. The Canon version supports TTL and HSS up to 1/8000s, while the built-in Godox 2.4GHz X wireless system means it can also become part of an off-camera setup later.
What You're Really Paying Extra For
The lithium battery is only part of the upgrade. There's a dedicated switch for moving quickly between TTL and Manual, a 10-level LED modeling lamp for previewing light direction, and a quick-release locking system for getting the flash on and off the camera without turning a traditional locking wheel.
Those conveniences don't necessarily make a single photograph better. They make the process of taking many photographs faster. The same thinking applies to how you carry the R100: a compact camera sling for quick access like the Peak Design Everyday Sling 6L makes more sense when you're carrying the R100 and a small amount of gear, while the Peak Design camera backpack for a larger kit gives you more room when flashes, lenses, batteries and other accessories start becoming part of what you bring to a shoot. Neither changes image quality, but choosing the right way to carry your gear can make the whole shooting process easier.
For someone photographing an event, however, missing a moment while waiting for a flash to recycle or dealing with depleted batteries is a different problem. That's where the V860III-C becomes easier to justify.
Why It Still Doesn't Replace My TT685II-C Pick
The R100 itself is an affordable camera, and the TT685II-C already covers the core jobs most owners need: TTL exposure, HSS, strong output, bounce lighting and access to the Godox wireless system.
So I wouldn't tell a beginner to spend more on the V860III-C just because its specification sheet looks better. If you're taking family photos, learning bounce flash, shooting occasional portraits or simply trying to improve indoor photography, the extra money is largely buying endurance and workflow convenience.
There are smaller considerations too. One buyer described the V860III-C as taking some practice to learn despite its extensive adjustment options, while another reported the hot-shoe mounting plate becoming loose after extended ownership. Those experiences don't establish that every unit will develop the same issue, but they're worth knowing before treating the more expensive model as automatically superior. And remember that not every useful upgrade has to change the photograph itself: an Acer USB-C SD card reader for transferring your R100 photos can simply make the part after the shoot easier, letting you move files from your SD card directly to a compatible USB-C laptop, tablet or phone instead of building your transfer workflow around the camera.
Who Should Choose the V860III-C?
Choose this over the TT685II-C when you already know you'll be doing events, repeated portrait sessions, longer indoor shoots, or other high-volume flash photography. That's where its lithium battery and faster recycling stop being specifications and start saving you interruptions.
If you're buying your first external flash for an R100 and don't yet know whether you'll shoot heavily enough to benefit from that, I'd still start with the TT685II-C. Put the extra money toward the V860III-C when your shooting volume gives you a reason to need it.

When You Want the R100 to Stay Small and Affordable
The Godox TT350C is the option I'd look at when buying a flash shouldn't defeat the reason you chose the Canon R100 in the first place. It's compact, relatively inexpensive, and still gives you Canon TTL, HSS up to 1/8000s, bounce capability, and Godox 2.4GHz wireless.
That combination makes it particularly interesting as a first external flash. You can let TTL handle exposure while you're learning, rotate the head to bounce light instead of pointing it directly at your subject, and eventually experiment with wireless lighting without replacing the flash immediately. As you start trying slower shutter speeds, self-portraits or more controlled compositions, a lightweight carbon fiber tripod for your Canon R100 like the SIRUI Traveler X-III gives you a stable camera position without turning this compact setup into something cumbersome to carry.
More importantly, we have direct evidence that this combination makes sense. Verified buyers in the Amazon screenshots specifically report using the TT350C with the Canon EOS R100. One describes it as a good physical size for the camera, while another reports that it fits and works well with their R100.
Small Doesn't Mean Stripped of the Useful Features
The TT350C is rated at GN36 and covers approximately 24–105mm with auto or manual zoom. It supports TTL, Manual and Multi modes, along with flash exposure compensation and front/rear-curtain synchronization.
The built-in Godox 2.4GHz X system is particularly valuable at this level. The TT350C can work within a larger Godox setup as your lighting skills grow, so choosing the inexpensive flash now doesn't necessarily mean throwing it away when you eventually try off-camera lighting. The same thinking can apply to camera support: a carbon fiber monopod for your Canon R100 like the SmallRig 65.6-inch model gives you portable support now, while having enough height and load capacity to remain useful if your camera setup becomes heavier later.
For travel, family photos, casual portraits and everyday indoor photography, that can be a smarter combination than buying a much larger flash simply because it has the highest output number.
Where Saving Money Starts to Cost You
This is also where I'd be careful not to oversell the TT350C. Its GN36 output is well below the GN60 TT685II-C, and the listing rates it for roughly 210 full-power flashes with a recycle range of approximately 0.1–2.2 seconds.
That difference matters more as the job becomes demanding. If you're bouncing light from higher ceilings, trying to get more reach, taking many flash photographs in succession, or expecting the flash to handle events regularly, the additional output and capacity of the TT685II-C give you considerably more breathing room. And once the R100 starts coming with you to events and longer shoots regularly, a 9H tempered glass protector for your Canon R100 screen is a small addition that helps put a replaceable layer between the LCD and the scratches, fingerprints and everyday knocks that come with carrying and handling the camera more often.
Battery choice matters too. The TT350C uses replaceable batteries rather than the dedicated lithium system found in models such as the V480-C and V860III-C. One R100 owner in the reviews specifically mentions pairing it with Eneloop rechargeable batteries, which is a sensible approach if you expect to use the flash regularly.
There is also some negative feedback worth acknowledging. One verified buyer reported that their unit developed battery and synchronization problems after initially working correctly. That's one buyer experience rather than evidence that every TT350C will fail, but it's another reason I wouldn't choose this model purely because it's cheaper.
Who Should Choose the TT350C?
Choose the TT350C if your priorities are low cost, compact size, occasional flash photography and keeping the R100 easy to carry. It's particularly appealing if this is your first flash and you want to learn TTL, bounce lighting and basic wireless flash without making a large investment. Keeping the rest of the setup straightforward makes sense too, and a Canon LC-E17 charger for your R100 battery gives you a dedicated way to recharge an LP-E17 outside the camera, which is especially useful because the R100 doesn't support charging its battery through its USB-C port.
But if the extra size and cost aren't major concerns, I'd still put the TT685II-C ahead of it. The TT350C wins by asking less of your budget and camera bag, not by outperforming the larger flash.

When You Want More Than a Budget Flash Without Going Full Size
The Godox V480-C fills an interesting gap for the Canon R100. Maybe the TT350C feels a little too limited, but you also don't want to move straight to a larger speedlight simply to get better battery performance and more output. This is the option that sits between those two approaches.
Its GN50 output gives you more lighting headroom than the GN36 TT350C, while the rechargeable 7.2V/2200mAh lithium battery is rated for up to approximately 650 full-power flashes. Maximum recycling is listed at around 1.7 seconds, so the upgrade isn't just about adding features; it gives you considerably more endurance for repeated shooting. And if that progression eventually includes interviews, talking-to-camera videos or content with two people, a two-person wireless microphone system for your camera like the DJI Mic Mini gives you two compact transmitters and a camera receiver without adding a bulky audio setup to your R100 kit.
For an R100 owner moving beyond occasional family photos into portraits, small events or more regular flash photography, that's a useful step up without automatically jumping to the V860III-C.
The Touchscreen Is More Useful Than It Sounds
One of the V480-C's biggest differences is its 2-inch color touchscreen, combined with physical controls. Flash settings can become intimidating quickly when you're learning TTL, manual power, wireless groups and synchronization options, so having information presented clearly can matter more than another specification you'll rarely use.
You still get the important photographic controls underneath that interface: TTL, Manual and Multi modes, HSS up to 1/8000s, flash exposure compensation, and front/rear-curtain sync. That gives you room to learn more advanced lighting without immediately outgrowing the flash. And if your R100 starts doing more video alongside photography, a DJI RS 4 Mini Combo for your Canon R100 gives you another kind of creative control, stabilizing handheld movement while adding the Tracking Module and Mini Briefcase Handle for subject-following and low-angle filming.
There's also a Smart Distance Readout that displays effective range information, plus a 10-level 2W modeling lamp. That modeling light can help you get an idea of where shadows and highlights will fall before firing the actual flash, which becomes more useful as you start paying attention to light direction rather than simply brightness.
It Has More Room to Become an Off-Camera Flash
The built-in Godox 2.4GHz X wireless system works as both sender and receiver, with the listing specifying 32 channels and wireless operation up to 100 meters. That gives the V480-C a second life if your lighting setup eventually moves away from the R100 hot shoe.
This is important when deciding how much to spend. You're not necessarily buying a flash that stays permanently attached to an entry-level camera. If you later add another Godox light or compatible trigger, the V480-C can become part of a more flexible lighting setup instead of being replaced. The same flexibility is useful for how you carry the camera: a quick-release camera strap for your Canon R100 like the Peak Design Leash lets you carry the camera around your neck, over your shoulder or crossbody, then quickly detach the strap when you move the R100 onto a tripod, gimbal or another supported setup.
USB-C charging is another practical advantage. If you're already carrying USB-C power for other gear, topping up the flash is simpler than building your entire shooting day around disposable or separately charged AA batteries.
Why I Still Prefer the TT685II-C for Most R100 Owners
The V480-C is more modern in several ways, but that doesn't automatically make it the better value. The TT685II-C gives you GN60 output, compared with GN50 here, while already covering the TTL, HSS, bounce and wireless fundamentals most R100 photographers are actually shopping for. If you're also building the R100 into a video setup, your next upgrade may have less to do with the flash and more to do with sound, so compare a wireless microphone for camera video before spending more simply to get extra flash features.
So the V480-C makes the strongest case when you specifically value its lithium endurance, touchscreen interface, modeling lamp and more compact approach. If those things don't solve a problem for you, paying extra simply because the V480-C is newer or more feature-rich isn't necessary.
The modeling lamp also comes with a practical tradeoff. One verified buyer reported getting only a few hours from the battery while leaving the modeling light on, despite otherwise praising the flash. That's a good reminder that the headline battery capacity doesn't mean every feature can run continuously without affecting endurance.
Who Should Choose the V480-C?
Choose it if you want more power and endurance than a small budget flash, but still care about keeping the R100 setup manageable. It also makes sense for a beginner who values a more visual interface and expects to explore off-camera lighting later. And if video becomes part of that same R100 setup, choosing a camera gimbal under $500 can give you room to stabilize moving shots without immediately turning a lightweight camera into an unnecessarily expensive filmmaking rig.
If your priority is simply getting the strongest value from your first serious R100 flash, the TT685II-C remains my pick. The V480-C becomes worth moving up to when its lithium battery, touchscreen and compact design are features you'll actually benefit from rather than extras that merely look better on the specification sheet.
Step up to GN50 output, lithium power, touchscreen controls and up to 650 full-power flashes without jumping straight to a larger setup. Check Price →
When You Care More About the Look of the Light
The Godox V1-C is the one I'd look at when your reason for upgrading isn't simply that you need a brighter flash. Its defining feature is the round flash head, which is designed to produce a broader, more even light pattern than a conventional rectangular speedlight head.
That makes the V1-C particularly interesting for portraits, weddings, indoor events and creative lighting, where you're paying attention to how the light falls across a face rather than just whether the scene is bright enough. If you also shoot video with the R100, that same shift toward more controlled-looking results can make a budget camera gimbal worth considering when you want smoother movement without spending heavily on a stabilizer built for a much larger camera rig.
You aren't sacrificing the features expected from a serious Canon speedlight either. The V1-C supports Canon TTL, manual flash, HSS up to 1/8000s, flash exposure compensation, front/rear-curtain sync and the Godox 2.4GHz X wireless system.
The Round Head Changes What You're Paying For
With the other flashes here, much of the buying decision comes down to output, battery system, size and controls. The V1-C adds another consideration: light shaping.
Its round-head design produces a more even spread from the center toward the edges, and the head also gives you access to Godox's magnetic modifier ecosystem. That makes it easier to add compatible diffusers, grids and other modifiers when you want to change the character or direction of the light.
This is where spending more can make sense for someone learning portrait lighting. Instead of treating the flash as something you point directly at the subject whenever a room gets dark, you have a system with more room for bounce flash, modified light and off-camera setups.
It Can Grow Beyond the Canon R100
The built-in 2.4GHz Godox X wireless system is another reason to consider the V1-C as more than an R100 accessory. It can communicate with compatible Godox lighting equipment, so the flash can eventually become part of a larger off-camera setup.
Its rechargeable lithium battery is also rated for roughly 450–480 full-power flashes, depending on the referenced listing specification, with recycling as fast as approximately 1.5 seconds. That's useful when you're shooting an event or portrait session and don't want to keep stopping to replace AA batteries.
There's also an LED modeling light for previewing your lighting direction before taking the photograph. It's not a replacement for a dedicated continuous light, but it can help when you're learning where your flash is actually putting the shadows.
Why It Isn't My First Recommendation for the R100
The biggest problem with the V1-C isn't capability. It's how much flash makes sense relative to the camera you're building around.
The Canon R100 is a compact, entry-level body. If you mainly want better family photos, indoor snapshots, occasional bounce flash or a straightforward first speedlight, you don't need to spend V1-C money to solve those problems. The TT685II-C covers the important fundamentals for considerably less, while the TT350C goes even further toward keeping the overall setup inexpensive and compact.
There is another tradeoff worth knowing. Some buyer feedback praises the V1 for its battery life, ease of use and lighting quality, but there are also reports of hot-shoe mounting durability problems. That doesn't mean every unit will develop an issue, but it's something I'd consider if the flash will regularly be mounted, removed and carried through demanding event work.
And because this is the Canon-specific V1-C, make sure you're choosing the C version rather than the Sony, Nikon, Fujifilm or Olympus/Panasonic variants shown alongside it in some listings.
Who Should Choose the Godox V1-C?
The V1-C makes the most sense if your Canon R100 is the beginning of your photography setup rather than the end of it. If you're becoming serious about portraits, weddings, events or off-camera lighting, paying more now gives you a flash that has considerably more room to stay useful as your lighting skills and equipment grow.
But I wouldn't buy it simply because it's one of the most premium options here. Buy the V1-C when you specifically want its round-head lighting system and expansion potential. If you mainly need a dependable flash that makes the R100 more capable without spending unnecessarily, the TT685II-C remains the more sensible overall choice.
Choose the round-head option when softer, more even light and a lighting system you can expand matter more than keeping the cost low. Check Price →
Which Canon R100 Flash Is Actually Worth Your Money?
With the Canon R100, spending more does not automatically mean buying smarter. A flash can cost a large percentage of what you paid for the camera itself, so the better question is what problem you need the flash to solve right now.
Someone learning bounce flash at home has very different needs from someone photographing paid events. Start with the job you expect the flash to do most often, then pay for the features that make that job easier.
Match Your Money to the Photography You Do
-
You want one sensible flash that covers almost everything:
The Godox TT685II-C is my first choice. You get Canon TTL, HSS up to 1/8000s, a GN60-class output, 20–200mm zoom, TCM and the built-in Godox 2.4GHz X system. It gives an R100 owner plenty to learn and grow into without immediately jumping to a premium rechargeable model. -
You bought the R100 because photography needed to stay affordable:
Look hardest at the Godox TT350C. Its compact body suits the small R100 particularly well, while TTL, HSS, bounce capability and Godox 2.4GHz wireless support give you much more control than a basic fixed flash. This is the option I'd favor when keeping the total camera kit inexpensive matters more than maximum power. -
You shoot often enough that changing AA batteries is becoming annoying:
The Godox V860III-C moves you to a rechargeable lithium battery system with up to roughly 480 full-power flashes and recycling as fast as around 1.5 seconds. That makes more sense for longer portrait sessions, events and repeated shooting where battery management starts affecting your workflow. -
You want modern controls without moving all the way to a round-head flash:
The Godox V480-C gives you a 2-inch color touchscreen, rechargeable lithium battery, GN50 output, TTL/HSS, a modeling lamp and Godox X wireless functionality. It is the more interesting choice when usability and quick adjustments matter as much as raw output. -
You want to build toward portraits, weddings or off-camera lighting:
The Godox V1-C is where I'd spend the extra money deliberately. Its round head, magnetic modifier compatibility, rechargeable battery and Godox X integration make more sense when lighting itself is becoming an important part of your photography rather than something you only use when a room is dark.
Spend on the Feature You'll Notice, Not the Spec Sheet
This is where an R100 buyer can easily overspend. TTL, bounce capability and reliable flash exposure can already make an enormous difference to indoor photographs. You don't necessarily need a premium battery system, touchscreen or round head to get that improvement.
On the other hand, buying the cheapest possible flash can also become expensive if you quickly outgrow it. If you already know that you want to experiment with off-camera flash, the shared Godox 2.4GHz X ecosystem across these models is valuable because your first speedlight can remain useful when you later add compatible triggers or additional lights.
Think about frequency too. For occasional family photos and learning flash, an AA-powered model can be perfectly reasonable. If you're shooting hundreds of photographs at events or during portrait sessions, faster recycling and a dedicated rechargeable battery become much easier to justify.
The R100 Doesn't Need the Most Expensive Flash Here
That's the important distinction. The V1-C and V860III-C are better-equipped flashes, but that doesn't automatically make either one the best purchase for every Canon R100 owner.
For this particular camera, I think the sweet spot is buying enough flash to remove the limitations you'll actually encounter while leaving money available for the rest of your photography kit.
That's why the Godox TT685II-C remains my overall recommendation for most Canon EOS R100 owners. It sits in the useful middle: substantially more capable than a bare-bones beginner flash, but without making you pay for premium conveniences you may not yet need.
Don't Let Bad Light Keep Limiting Your Canon R100
A new lens can change what your R100 can photograph. A flash changes how many situations you can photograph well in the first place.
That difference becomes obvious the next time you're indoors and the camera starts pushing ISO higher, faces fall into ugly shadows, or a moment happens somewhere the available light simply isn't good enough. You can correct some of that afterward, but editing can't give you lighting that was never there.
If those are already the photographs frustrating you, waiting doesn't make the R100 better at them. A capable speedlight gives you control over the problem instead of asking the camera to compensate for it.
Buy for the Photos You're Missing Now
You also don't need to turn a relatively affordable Canon R100 into an expensive lighting kit just to get that improvement.
For most owners, the Godox TT685II-C already reaches the point where the flash can grow with your photography. You get Canon TTL when you want the camera and flash to handle exposure quickly, while manual control gives you somewhere to go as you learn more about lighting.
Its tilting and rotating head also opens up one of the upgrades that matters most when moving beyond basic direct flash: bouncing light from ceilings and walls. Add HSS up to 1/8000s, 20–200mm zoom, TCM and the built-in Godox 2.4GHz X system, and you're not buying something you should immediately need to replace as your skills improve.
That's why I wouldn't keep postponing the purchase just to decide whether one extra premium feature is worth having. If the TT350C's smaller size, V860III-C's rechargeable battery, V480-C's touchscreen or V1-C's round head solves a specific problem for you, choose that model.
Otherwise, the TT685II-C is the safer place to stop comparing and start improving the photographs you're already taking.
Check the Listing While You're Ready to Choose
The one thing I wouldn't lock into this article is an Amazon price. Listings, availability and offers can move independently, and that can change which of these five represents the better buy on the day you order.
So if the TT685II-C is already the right level of flash for your R100, check its current listing before spending more on the rechargeable models. If the current offer makes sense for your budget, you're getting the model I'd choose for the broadest mix of capability and sensible spending on this camera.
Which Flash Should You Buy for the Canon EOS R100?
After comparing all five, the choice becomes much easier when you decide how far you actually want to take flash photography with your Canon R100.
If you simply want a small, affordable first flash, the Godox TT350C is the easiest place to start. If you regularly shoot longer sessions and want rechargeable power, the V860III-C makes that upgrade worthwhile. The V480-C is the more modern alternative when touchscreen control and a rechargeable battery appeal to you, while the V1-C is the one I'd reserve for photographers deliberately moving toward portraits, events and more creative lighting.
But if you want to buy once without spending far beyond what makes sense for an R100, I'd choose the Godox TT685II-C.
My Final Buying Check
- Want the best overall balance? Choose the Godox TT685II-C.
- Keeping your first flash inexpensive and compact? Choose the Godox TT350C.
- Shoot frequently and don't want to rely on AA batteries? Step up to the Godox V860III-C.
- Want rechargeable power with a touchscreen interface? The Godox V480-C is the better fit.
- Getting serious about portraits, weddings or creative lighting? Consider the Godox V1-C and its round-head system.
The mistake I'd avoid is choosing the most expensive flash simply because it has the longest feature list. Your R100 doesn't need every premium feature to produce dramatically better flash photographs. It needs a flash that gives you enough control to improve the light without making the rest of your setup unnecessarily expensive.
For that reason, the Godox TT685II-C is where I'd stop for most Canon EOS R100 owners. You get TTL for quick exposure, manual control as your skills grow, HSS up to 1/8000s, a versatile 20–200mm zoom range and the Godox 2.4GHz X system if you later decide to experiment with off-camera lighting.
Price and availability can change. Check Amazon for current listing details.
