The Canon EOS R3 is a spectacular camera that is set to take on the likes of the Sony A1 and other flagship mirrorless cameras. It has excellent specs and is worth buying - if you do not have one yet.

Now, the Canon R3 has just started shipping out last November 26 but it gets sold out easily. Canon estimates that it might even take 6 months for them to fulfil all pre-orders. That’s a lot of units sold and it speaks about the quality of this camera.

If this is your first camera, then here are the must-have accessories for the Canon EOS R3. And if you are a seasoned photographer, these accessories are worth checking out too.

Best Canon R3 battery

Canon LP-E19 battery

The Canon EOS R3 uses either the Canon LP-E19 battery pack or the Canon LP-E4N battery. Both are undoubtedly great for the R3 but the LP-E19 has an edge when it comes to size.

The LP-E19 Li-Ion battery has 2700mAh while the LP-E4N has 2450mAh. It is a very small difference in capacity. However, considering its price, the LP-E19 is a better choice.

The LP-E4N battery is around $164.95 while the LP-E19 is $163 so choosing the latter is a no-brainer.

If you have the regular LP-E4 battery, it will not work according to Canon. Just use the LP-E4N or the LP-E19.

For a third-party battery, the Watson LP-E19 can be considered as a backup. It only costs $99.99 and comes with a 3500mAh capacity. 

Best battery charger

Canon LC-E19 battery charger

The Canon LC-E19 battery charger is perfect for both the LP-E19 and the LP-E4N batteries. It can charge the LP-E19 from 0 to full in 170 minutes. Meanwhile, the LP-E4/LP-E4N batteries fill up in 140 minutes.

The good thing about this charger is its dual-slot. You may charge two batteries simultaneously which is great if you have multiple batteries to charge.

The LC-E19 charger costs $369 which is not bad considering its functionality.

There is a compatibility issue regarding the Canon LC-E19 and the LP-E4N batteries though. Canon said that this is due to the safety standards stated for AV/ICT products.

If you are looking for a more affordable option, then the Watson Duo Battery Charger for Canon LP-E19, LP-E4, and the LP-E4N is a neat budget option.

For $89.99 you are getting a dual-slot charger with sequential battery charging with overheat and short-circuit protection. It has LED charging indicators too.

Now, sequential charging might not be the best option for some photographers. This means that it charges one battery first and once it is full, it goes to the second battery next. It is not ideal if you want to charge multiple batteries at once. But for its price, it's a neat backup.

Does the Canon R3 support USB in-camera charging?

According to Canon, the Canon EOS R3 supports USB charging with the USB Power Adapter PD-E1 for the Canon LP-E19 batteries. But it will only work if the unit is turned off.

The Canon LP-E4N battery is not supported by this feature.

Powering the camera while using the USB PD-E1 charger is not supported too.

Which USB-PD chargers work with the Canon R3?

The Canon USB PD-E1 power adapter supports 5V at 3A (15W) and 9V at 3A (27W) charging. This means that if you are going to look for another USB-PD option, it should have matching specifications.

There is no “best” recommendation for USB-PD chargers at the moment due to the complications of in-camera charging for the Canon R3, unlike the Canon R5 and R6.

It is highly recommended to use the Canon USB PD-E1 power adapter or to use a separate battery charger to avoid any problems in the future.

Best Screen Protector for the Canon R3

Expert Shield Screen Protector

The Expert Shield Screen Protector is an affordable option if you want to protect your screen from scratches. It is the same recommendation that we have in our Canon R5 and R6 must have accessories round-up.

For $20 you get a screen protector with anti-glare and the display remains clear. It also comes with a lifetime warranty.

Best Canon EOS R3 CFExpress Type B Memory card

Delkin Devices Black CFexpress Type-B Card

The Canon R3 accepts two types of memory cards. It works with the faster CFexpress Type B cards and regular UHS-II SD Cards. Eye-fi cards and Multimedia Cards (MMC) are not supported.

The best CFexpress Type B card that is worth considering for the R3 is the Delkin Devices Black CFexpress cards.

For this price, you are getting a max read speed of 1725 MB/s and a max write speed of 1530 MB/s. 

Delkin cards are reliable so you are surely getting a lot for your money.

Best UHS-II SD Card

Delkin Devices Black UHS-II SD Card

The Delkin Devices Black UHS-II SD Card is great if you do not need the super-fast read/write speed that a CFexpress Type B card provides.

This UHS-II SD Card has a max read speed of 300 MB/s and a max write speed of 250 MB/s. It is not slow. But if you are taking a lot of burst images and high bitrate videos then the CFexpress is a better investment.

The Delkin Black cards come at 32GB, 64GB, 128GB, and 256Gb versions. The 128GB is priced at $190. There is a 2-pack version too.

This card is also water, dust, and shock resistant with X-ray proofing. Delkin claims that it can withstand 45 pounds of impact too. So if you are looking for a rugged card then it is worth getting.

Best Memory Card Reader

Delkin Devices CFexpress Type-B and SD Card reader

The Delkin CFexpress USB 3.2 Card Reader is a safe bet when it comes to CFexpress readers. It is compact and easily fits into your bag or camera pocket.

There is a rubber protection too for the CFexpress card slot and may serve as a protective case whenever it is not in use.
It includes a USB-C to USB-C cable for modern laptops while a USB-A cable is also included.

For USH-II SD Cards, the Kingston Mobilelite Plus is an affordable option. It supports UHS-I and UHS-II cards at a compact size. Speed is not compromised too due to the USB 3.2 connection.

Best Memory Card case

Pelican 0915 Memory Card Case

Pelican makes some of the best camera cases in the world and now they have protective cases for memory cards too.

The Pelican 0915 Memory Card Case fits 12 SD cards, 6 mini SD cards, and 6 micro SD cards. 

Meanwhile, the Pelican 0965 Micro Memory Card Case fits six CFexpress or XQD memory cards.

Both models are shock resistant and waterproof. It can also withstand harsh elements that may damage your memory cards.

Best Flash Bracket for the Canon R3

ProMediaGear BBGv2 Boomerang Flash Bracket

There are a lot of flash brackets available in the market. But the ProMediaGear BBGv2 Boomerang Flash Bracket is the best one out there. 

This flash bracket is tall enough to accommodate cameras with a battery grip such as the Canon R3. It is lightweight and the adjustment arm is easy to reach.

The BBGv2 is also the second version already with an improvement on its ergonomics. The company removed the quick release knobs for a more comfortable hand position while shooting.

The bracket that comes with it is also modular which means you may use it as a base for an L-Bracket, camera grip and handles.

Best Tripod for the Canon R3

ProMediaGear TR344L Pro-Stix Carbon Fiber Tripod

The Canon R3 is light compared to bulky DSLRs. But it is a little bit heavier compared to the Canon R5 or the R6 because of their battery grip.

The ProMediaGear TR344L Carbon Fiber Tripod is a great companion for shooting landscapes or wildlife because of its height and weight. It is made of carbon fiber with four leg sections and only costs $1079.95.

The max load is 60lbs which is perfect for the Canon EOS R3 with a super-telephoto lens attached. 

It is also compact when folded so carrying it is not a problem as well as it only weighs 4.3 lbs. It might not be the lightest tripod in its class but it is a reliable camera support that you can bring anywhere.

There are three ball head options from ProMediaGear too. The BH1 is a huge ball head that is perfect for long lenses but is not ideal for traveling due to its bulkiness. However, the BH50 is another option if you need a smooth ball head without breaking the bank.

Which rain cover should you get for the Canon R3?

ThinkTank Rain Cover

Despite having a weather-sealed body, using a rain cover for your camera is advisable for added protection. So if you are shooting outdoors regularly, the Think Tank Hydrophobia Camera Cover might be the one for you.

There are no specific models to recommend as it would depend on your camera and lens setup. However, all Hydrophobia models can give you peace of mind while shooting in the rain.

These rain covers have a 3-layer material with sealed seams. It is perfect for shooting in the rain or dusty conditions while allowing access to the camera viewfinder and controls.

Best external flash for the Canon R3

Canon Speedlite 600EX II-RT

The flagship Canon Speedlite 600EX II-RT is still the best external flash for the Canon R3 with a maximum power output with a GN of up to 60. 

The zoom range is enough for any focal range and it also features a 20-200mm motorized zoom range. The TTL capabilities make it easier to shoot with on-camera flash during events or in situations where the light constantly changes.

Just like the Canon R3, this external flash has a weather-sealed body. Not even the rain can stop you from shooting.

This Speedlite is pricey. You can get one from $450 onwards but for the features and capabilities, it is definitely worth it.

Best third-party flash for the Canon R6 and R5

Godox V1 Flash

The Canon 600EX II-RT is a great flash. There is no doubt about that. But for someone looking for a more affordable option or even a backup Speedlite, then the Godox V1 Flash is worth considering and it is priced at $260.

It is compatible with E-TTL and has a powerful 76W output. It does have an unconventional round head which may make it inconvenient for some accessories. But the good thing is Godox has its own ecosystem for its flashes.

This flash has a 1.5 second recycle time. It also supports a High-Speed Sync of up to 1/8000s. 

Best Wireless Flash Trigger

Canon Speedlite Transmitter ST-E3-RT

The Canon ST-E3-RT Speedlite Transmitter remains to be the best first-party Canon flash trigger for the Canon 600EX-RT and other Canon flashes.

This transmitter has the ability to control up to fifteen Speedlites with the option to separate flashes into five groups.

You may control multiple speedlites plus it has E-TTL support and multiple functions. The transmission distance is up to 30 meters too.

It is priced at $285 and it is currently the best trigger for your Canon R3 and other Canon cameras.

Best off-camera TTL Flash Cord for the Canon R3

Canon OC-E3 Off-Camera Shoe Cord

If you are using a ProMediaGear flash bracket or a handle then the Canon OC-E3 Off-Camera Shoe Cord is a great way to power your flash.

It supports E-TTL and can trigger the majority of Canon flashes available in the market. Just connect it to your camera and you may use your flash off-camera at a limited distance.

For a flash cable, it is a little bit expensive at $70 considering there are third-party options out there. 

Best Microphone for the Canon EOS R3

Rode NTG Hybrid Mic

The Canon EOS R3 can take 6K, 4K, and full HD videos at different frame rates. For a flagship camera, this is enough to satisfy videographers out there.

Like other cameras, recording videos is better with a separate microphone and if you want a shotgun microphone, you may consider the Rode NTG Hybrid Mic.

Rode has been making excellent audio gear for several years now and this microphone is one of the best out there. It solves audio issues like wind noise and it can produce clear audio without the need for adapters.

It also has a 30-hour battery life with multiple control options.

Now, if you want a lavalier microphone for your Canon R3 then the Rode Lavalier Go should be your pick. There are instances where a shotgun microphone is less than ideal and the Lavalier Go would be the best option.

All you need is to clip the lavalier mic to your clothing and you are good to go. 

The Lavalier Go is priced at $280 and it's an investment considering its reliability especially if you are recording videos all the time.

Best Canon EOS R3 Bracket Plate

ProMediaGear PBCR3 Arca-swiss Plate

The Canon EOS R3 is a versatile cameras that works well with any photography genre. Hence, it needs a bracket plate that works really well with any tripod or camera accessories.

The ProMediaGear PBCR3 Canon R3 Arca Bracket Plate is possibly one of the best plates out there. It is Arca-swiss compatible and works with any Arca-clamps. 

This bracket plate is also made of lightweight aluminum so it is not worrisome to use considering the Canon R3's weight.

Lastly, the PBCR3 serves as multipurpose plate. It can be transformed to a handle grip, L-bracket, flash bracket, and even a tiny rig.

Best Canon EOS R3 L-Bracket

ProMediaGear PLCR3

The ProMediaGear PLCR3 is a custom L-bracket that works with the Canon R3. It hugs the camera's body tightly to prevent unwanted movement or shake. 

The vertical part is also adjusted to accommodate the Canon R3's fully articulated screen. The ports are also unobstructed making it a joy to use - no more fiddling with the L-bracket just to reach the left ports.

It is also made so that the battery compartment is accessible, unlike other L-brackets.

The PLCR3 is made of aircraft-grade aluminum so it does not add too much weight on a setup.

The ProMediaGear PLCR3 comes with a 5-year warranty and a money-back guarantee too if you are not satisfied with it.

Best Canon R3 video monitor

Atomos Ninja V

Speaking of video recording, you need an external video monitor if you want to set up your Canon R3 as a video rig. 

The Atomos Ninja V is the cream of the crop when it comes to external monitors. It is pricey, indeed, but there are a lot of features not found on other monitors.

The Ninja V has additional exposure tools like waveform and vectorscope while supporting different 3D LUTs.

Using an external monitor also prevents overheating as the recording is done off-camera. 

Best Video Rig for the Canon R3

ProMediaGear VRC1K Camera Rig

To complete your video setup, you will need the ProMediaGear VRC1K Adjustable Video Cage Rig Kit. It is universal so it fits the Canon R3 and the height is adjustable.

This rig has multiple ¼-20 threads for accessories and there are non-threaded adapters too. With this rig, you can mount the external monitor, LED lights, and external microphones.

You may also attach the ProMediaGear handle for a stable grip on your camera. Moreover, this handle has multiple cold shoes for more accessory mounts.

This video rig is customizable and modular so it depends on you on how you would set it up.

Best Video Slider for the Canon R3

ProMediaGear Duo Slider

The ProMediaGear PMG Double-Sided Slider is an excellent video slider as you get two types in one. You get a straight rail and a curved rail that you can use for varying shots.

This slider works with any tripod as it has a standard tripod mount so if you need to lift it up the ground, you would have no problem.

There are different sizes available. Depending on the kind of shoot, choose one that suits your genre the best. 

There is a motor available too. The PMG VSMDC1 controller makes it easier to take videos automatically. It also reduces camera shake as you no longer need to move the camera manually.

Like other ProMediaGear products, this slider is made of T6061 aluminum and is durable and easy to carry around.
