Canon EOS R3 Review – Mirrorless monster for sports and wildlife photographers

The Canon EOS R3 is the company’s first high-end mirrorless camera, and it was developed specifically for photojournalism, sports photography, and wildlife photography. It is a full-frame 24MP camera constructed around the ‘RF lens mount, and in many aspects, it looks to be a flagship camera other than the absence of the number ‘1’ in its designation. Other than that, it has all the characteristics of a flagship camera.

The Canon EOS R3 is built around a Stacked CMOS sensor, which not only provides a fast readout for rapid shooting, responsive autofocus, and low rolling-shutter video but also includes a host of other innovative features, such as the return of Canon’s Eye Control autofocus system, which was last seen in film SLRs during the late 1990s and early 2000s.

What’s new 

The Canon EOS R3 is a superb pro-level body that combines all of the features that Canon has iterated on with the EOS-1D X Mark III as well as the EOS R5 and R6 cameras. There is at least one minor modification that has the potential to dramatically streamline the processes of some photographers. The majority of its new capabilities are derived from its newly built sensor, but there is at least one smaller refinement that potentially does this.

Key takeaways

  • The new sensor has a high scanning speed, produces highly clear images, and can flash-synchronize with an electronic shutter at 1/180 of a second.
  • The AF system is becoming increasingly focused on subject tracking, and it is trained to detect animals, humans, and sports-specific machinery through the application of machine learning (race cars, motorcycles)
  • Eye Control AF is back, and it’s better than ever, with a solid implementation and consistent performance (based on our experiences so far)
  • Even while the viewfinder has 5.76 million dots, it does not win the award for highest resolution, but the OLED panel can display an image that is stunningly faithful to the scene in front of the camera.
  • Measurements of direct white balance may now be performed with more ease than ever before.
  • New alternatives for connectivity are available to both experienced professionals and skilled amateurs alike

Stacked CMOS sensor

A newly built Stacked CMOS sensor, which is entirely designed and manufactured in-house, serves as the R3’s central processing unit (CPU).

Silicon is produced into layers, which are then meticulously aligned and linked to one another using a method called stacked CMOS, which is the next phase of technology after BSI.

Because of this, they are able to build with a greater degree of freedom because the intricacy of one layer of the chip does not constrain what may be done with the layers above or below it.

The new chip implements Canon’s Dual Pixel AF architecture, which allows for the capturing of each output pixel by employing a left-looking and a right-looking half-pixel respectively.

This gives the camera a stereoscopic image of the scene, which it can analyze to determine the distance between subjects (much as humans do, using the offset between left and right eyes).

This has the benefit of turning the entire sensor into an AF sensor, and it does so without significantly affecting the image quality in any way.

We have not had the opportunity to check the dynamic range of the R3 (which is effectively a measure of how much or how little electronic noise is being added by the camera), but we have estimated the readout rate to be a fraction under 1/200 sec. This is consistent with the promise of flash sync in electronic shutter mode at shutter speeds of up to 1/180 sec.

This fast readout is the foundation for all of the camera’s high-speed capabilities, including its continuous shooting rate of 30 frames per second, its autofocus system that is capable of performing 60 AF and AE calculations per second, and its electronic viewfinder (EVF) that can refresh at 60 or 120 Hz and does not need to blackout when taking pictures using the electronic shutter mode.

Updated AF system

An expanded version of the autofocus system that Canon has been working on for its mirrorless cameras is what you’ll find in the R3. That system, in turn, shares a lot of similarities with the logic that underpins Canon’s AF systems for its DSLR cameras.

You are provided with a number of different AF points and zones of varying sizes, but now you have the option to choose any one of them as the beginning point for subject tracking (rather than Tracking being a completely separate mode).

This AF system has a highly capable subject recognition system that can focus on eyes, faces, or bodies, depending on which the camera can discern. This technology is built right into the AF system.

It will automatically transition between each of these functions so that it does not lose track of your target even if they look away from the camera or turn their back entirely on the device.

Faces may now be recognized in a wider range of demanding environments thanks to improvements made to the system in the R3.

The camera may be programmed to prioritize other sorts of subjects that it has been taught to identify in addition to humans. The other two options are “Animals” and “Motorsport,” while the default setting is for the camera to prioritize people.

By selecting the ‘No Priority’ option, the subject recognition function of the AF system may be disabled, leaving the system to instead just track subjects based on color and distance.

But arguably the most significant modification is that, in most modes, the camera will no longer focus only on the subject that is located below the AF point that you have selected. Instead, it will look in the area around the AF point for possible subjects to investigate.

Although it may not seem like much of a change at first, it has a significant bearing on how well Eye Control operates and how well the camera performs overall.

In addition to this, the R3 has a new AF zone mode that allows the user to design their own rectangle AF area. This area should be tailored to the region of the scene in which the subject of the photograph is anticipated to appear.

As an illustration, Canon provides the idea that using a broad horizontal box would enable a tennis player to be captured above the net without the possibility of the net diverting the attention of the camera.

Motorsport recognition

The EOS R3 has been taught to detect motorsport themes in addition to being able to distinguish humans and animals using its built-in recognition capabilities.

In particular, it has been taught to distinguish racing automobiles and motorcycles, and Canon has stated that if it is directed at domestic vehicles, it may not operate to the best of its capacity.

A “spot detection” option is included in the motorsport recognition tool. This option allows the user to concentrate on a particular aspect of the topic when it is accessible.

Therefore, when it comes to motorcycles and open-wheel racing cars, the camera will aim to concentrate more on the rider’s or driver’s helmet than it will on the vehicle as a whole.

Eye Control AF

The rebirth of Canon’s Eye Control AF system, which monitors the user’s eye position so that the AF point can be positioned over the part of the scene they’re looking at, is perhaps the feature of the R3’s autofocus (AF) system that will garner the most attention. The R3 also features a new autofocus (AF) system called Dual Pixel CMOS AF.

It works in the same way as the version that Canon developed in the 1990s, with a sequence of infrared beams that are directed at the user’s eye in order to determine where the eye is located as it moves around the picture. Calibration of the system is straightforward, and according to Canon, it improves in precision the more times it is subjected to the procedure.

When you start focusing after giving the shutter button a half-push, the autofocus point will move to the place that you are looking at by default. However, there is an option that allows you to restrict the movement of the AF point to just when you press a certain button.

We found that the Eye Control system can be made to work fairly reliably with just a few calibrations and that it appears to work well because the camera will select a subject near to the AF point or zone, rather than just one directly under it. This indicates that the system is functioning correctly.

This indicates that the location of your autofocus (AF) point does not need to be pixel-perfect for the camera to successfully focus on the desired subject.

The system demands a little bit of confidence at the beginning, and Canon warns that it won’t function as well for everyone’s eyes (pale blue eyes causing the most problems, we’re informed), or for photographers who use glasses. However, it does work quite well for those who don’t wear glasses.

It can also have trouble calibrating itself if there is a lot of intense ambient light that is present surrounding the viewfinder, but our first impressions of the camera were extremely favorable.

And, as you might think, the R3 does not require that you use Eye Control. The camera features the same joystick and IR-driven Smart Controller that is included on the EOS-1D X Mark III, so there is nothing stopping you from using it that way if that is how you would rather use the camera.

Canon claims that the viewfinder of the EOS R3 is an entirely new design, despite the fact that it had previously employed an electronic viewfinder display with 5.76 million dots.

Not only does it have redesigned optics that direct infrared light to the Eye Control AF sensor, but it also has the capacity to refresh at up to 120 frames per second with a decreased amount of latency, making it more suitable for use when photographing sports.

During our shooting, it seemed as though this option had the same level of detail as the regular mode.

Additionally, Canon has included a setting called “Optical Viewfinder Simulation” in its cameras. This builds on Fujifilm’s similarly named mode, which provides a preview of the scene without the currently selected color mode being applied to it and which does not adjust in response to changes in exposure settings. It also provides a preview of the scene without adjusting for changes in the exposure settings.

Canon takes things one step further, however, by exploiting the wide dynamic range that its OLED display is capable of producing. This means that bright highlights appear brighter, relative to the mid-tones, and shadows don’t clip to black so aggressively: giving a more lifelike interpretation of the scene than existing EVFs, which will help DSLR users feel more at home with their cameras.

If you want a preview that accurately reflects the changes you make to the exposure, you have the option of having the viewfinder simulate exposure, simulate exposure and depth-of-field (DoF), or only simulate exposure when you press the DoF preview button. All of these options give you a preview that accurately reflects the changes you make to the exposure.

Anti-flicker modes

The electronic shutter on the R3 is speedy, but it is still not nearly as quick as a mechanical shutter may be, which means that there is a little higher chance of banding when the camera is pointed toward flashing screens and signs (something increasingly common at sporting events).

The R3 comes equipped with a clever anti-flicker setting to assist with this issue. The first component of it is simply a continuation of the technology that was previously presented with the EOS 7D II in the year 2014.

This synchronizes the shutter to the flicker of the lights, which causes the exposures to be made at the brightest point throughout the cycle of the flickering lights. It can monitor the flicker of lights running at up to 120 Hz.

This option may slow down the continuous shooting rate, depending on the type of shutter the camera is trying to sync with and the flicker frequency. Utilizing its entirely electronic shutter, the camera is capable of maintaining a shooting speed of 24 frames per second even when subjected to a lighting frequency of 120 Hz.

The second component, which is referred to as HF Anti-Flicker, is made to be compatible with the significantly quicker flicker that is produced by LED lights and display panels. This gives you the ability to manually adjust the shutter speed in extremely minute increments, allowing you to zero in on a speed that minimizes the appearance of banding in the image.

There is also an automated mode that can identify the flicker rate in the image (between 50 and 2011.2 Hz) and then fine-tune the shutter speed to reduce the likelihood of a collision between the two rates.

Direct WB capture

The capability to immediately capture a custom white balance reading demonstrates how fundamentally Canon has rethought this camera. Although this is a relatively minor function, it demonstrates how fundamentally Canon has rethought this camera.

The process of shooting a neutral frame, using the menus to select it, and then deriving a custom white balance from that frame (while also remembering to select custom as the WB mode) has been required of Canon owners for a significant amount of time. This process was particularly aggravating when shooting video.

Because of this modification, Canon has at long last brought its cameras into conformity with the behavior of all other cameras now available on the market.

In addition, Canon claims that the R3’s auto white balance has been improved through the use of machine learning. This allows the camera to better comprehend scenarios and avoid being confused by things like landscape photographs that are predominately composed of vegetation.

Quality of the Image

When compared to other recent “competing” mirrorless cameras, such as the Nikon Z9 and Sony A1, the Canon EOS R3 is a bit of an anomaly in terms of its overall imaging resolution. This is despite the fact that the R3 is priced similarly to a flagship camera.

In contrast to the Z9 and A1, both of which use sensors with a high resolution, the EOS R3 is more analogous to its EOS 1D X-series relatives, which include a sensor with a megapixel count that is on the lower end of the scale. When compared to other recent full-frame cameras, the Canon 1D X Mark III’s sensor only has 20 megapixels, which is a resolution that is considered to be somewhat poor.

The Canon EOS R3, on the other hand, features a full-frame sensor with a resolution that has been increased to 24 megapixels. When compared to the resolution of more costly current full-frame cameras, its resolution is still very modest.

What you get in exchange for giving up some of the R3’s ability to capture extremely fine details is exceptional performance in low light, extraordinary speed, and performance, as well as lightweight and manageable file sizes (for stills, that is). Because of this, the EOS R3, much like the 1D X III, is laser-focused on its ideal user. Primarily, the camera is designed with photojournalists and sports photographers in mind.

A camera’s speed and dependability, as well as its capacity to edit and/or send a large number of photographs as soon as possible, are all more important in these kinds of circumstances than the camera’s ability to produce images with an extremely high resolution.

But does the fact that the Canon R3 utilizes “just” a 24-megapixel sensor indicates that the photographs it takes are of poor quality because of this limitation? In point of fact, the reverse is true. The R3 produces great photographs, whether the ISO setting is set to a low value or one of the higher settings.

However, the relatively low resolution places you at a disadvantage in comparison to other cameras with better resolutions, particularly if the sorts of objects you wish to capture, such as birds and other forms of wildlife, require a higher level of detail.

As I’ve said in some of my earlier reviews, one of my preferred types of photography is wildlife photography, and in particular, bird photography. I was prepared with the EOS R3, which has an advanced focusing system with eye-tracking and bird-detecting capabilities. My goal was to test how well this brand-new high-end camera handled the challenge.

When it comes to photographing birds and other forms of wildlife, I knew going in that the R3 would put me at a bit of a disadvantage in terms of image quality. I will analyze the performance of the autofocus system in a later section. Because the sensor only has 24 megapixels, there is not a great deal of leeway for cropping photographs after the fact, especially when compared to megapixel behemoths such as the Sony A1, the A7R IV, the Nikon Z9, or the Canon R5.

Because each of these cameras also features animal-detecting eye-AF in some form or another, they are, in many respects, superior to the R3 when it comes to being able to take photographs of birds. The most important factor is that birds, particularly the little songbirds that I saw, are typically rather far away, shy and difficult to approach, and, well, tiny. This was especially true for the small songbirds that I saw.

Even though I was using an RF 100-500mm lens, I still ended up with a number of images in which the subjects were relatively unnoticeable in the frame and required a significant amount of trimming in post-production. In circumstances such as these, a sensor with a better resolution can be of great assistance.

After all of that has been said, is the Canon EOS R3 capable of taking photographs of birds to a high standard? Absolutely! To get closer to your subjects, you might need to be more careful (or have a little bit more luck), or you might need to be willing to settle for compositions that are less cropped.

Amazing images of birds and other animals may be taken with the R3; these pictures have a surprising level of fine detail, rich colors that nevertheless seem natural, and excellent tonality.


The EOS R3’s ability to take still photographs is just as impressive as its video recording capabilities. To offer oversampled DCI 4K video at up to 60p, it can employ the full 6K width of its sensor. Alternatively, it can sub-sample the complete width to deliver 4K at 100p or 120p with the same angle of view.

In comparison to DCI capture, there is also the possibility of shooting in the more squared-off 16:9 aspect ratio of UHD, which effectively crops the sides in.

Video restrictions

Raw capture and 4K/120 recording both require a CFexpress card with a transfer speed of more than 400 megabytes per second.

The need falls to 200MB/s when raw lite recording is used or when all-in-one 4K/60 capture is performed. The vast majority of other modes are able to be recorded onto a quick SD card or a CFexpress card, with the requirements becoming progressively less stringent as the framerate and quality are decreased.

Canon claims that All-I 4K/30 recorded from 6K should not be temperature restricted; however, recording of 60p 4K or 6K Raw is likely to end after around one hour (at 23°C/73°F), even with the Auto Temperature Power Off setting set to ‘High.’

The All-I 4K/120 set is the most difficult for the camera to achieve, with a time estimate of 12 minutes. All of these values are based on the assumption that the camera has not been utilized, thus any stills photography that was done in advance would reduce them.

Communication via wired and wireless networks

The Canon EOS R3 features built-in Wi-Fi capabilities, as one might anticipate from a modern camera, and it also has an Ethernet port, as one might anticipate from a camera geared toward professionals, so that users may make connected connections.

On the R3, you receive access to the whole set of capabilities provided by an EOS-1D X Mark III with a WFT wireless transmitter installed. This allows you to do things like transfer files directly from the camera via FTP, for example.

There is also an optional adapter that allows a smartphone to be attached to the camera’s USB connection, allowing its network capabilities to be utilized, offering up to 5G data speeds when using the Mobile File Transfer app. This accessory may be purchased separately.

Connectivity is one of the elements that are of considerable relevance to a large number of professionals; however, it is also the one that we’ve had the least amount of opportunity to test out of all of the features. When we have more time with a camera capable of full production, we will look at this aspect in a much more critical manner.

Body and handling

The EOS R3 sports a design that immediately evokes Canon’s previous 1D-series cameras. It has a curving dual grip design and a button arrangement that is nearly identical to that of the previous EOS-1D X Mark III. The R3 is noticeably more compact than the DSLR, which is obviously the most significant difference between the two. Because the R3 does not require a huge optical prism, the protrusion that can be found at the top of the camera is far less considerable.

Key takeaways

  • The Canon EOS R3 is the company’s second camera to include an autofocus ‘Smart Controller’ within the camera’s AF-ON buttons.
  • Experienced Canon photographers will find the three-dial design to be very familiar and comfortable.
  • Our preliminary testing revealed that a screen that can completely articulate is both convenient and robust.
  • The multi-function “hot shoe” of the camera may be used for more than simply flashes.
  • It takes the LP-E19 battery from the 1D X III, and you can get by just well with some of the earlier batteries from the 1D series (though not all of them will support USB charging)
  • Mixed storage allows for greater flexibility but results in varying write rates.

The first thing that should be brought to your attention is that the arrangement of the joystick and infrared Smart Controller on the R3 is identical to that of the EOS-1D X III. An infrared beam of light is used to monitor the movement of your thumb as it swipes across the surface of the smart controller, which also functions as the button for turning the autofocus on and off. This gives the smart controller the functionality of an inverted optical mouse.

If you do not want to rely on the Eye Control system, the combination of the two gives you two alternatives for quickly moving the autofocus point on your camera. In general, we’ve found that the joystick is fantastic for making little, precise adjustments, such as pushing a point or two from the current location, but the Smart Controller is typically more suited to fast making massive hops across the AF array.

Arrangement of three dials

The ‘Rate’ button has been relocated to the top left corner of the camera, and the ‘Info’ button has been moved to the right side of the main LCD. Other buttons have also been rearranged. The most notable modification that has been made to the R3’s physical controls is the addition of a third command dial, which can be found on the right side of its rear right shoulder.

Instead of striving for complete uniformity with the 1D models, Canon is bringing some of the ergonomic advancements that it has made with its R-series cameras to its professional line of cameras. This is seen by the fact that the “Mode” button is located in the middle of the dial.

In Manual mode, the three dials that control aperture (front), shutter speed (shoulder), and exposure compensation (rear) can be easily customized to provide access to aperture, shutter speed, exposure compensation, or ISO in whatever order you prefer.

By default, the three dials control aperture (front), shutter speed (shoulder), and exposure compensation (rear). Sadly, there is no dial option available for accessing the minimum shutter speed while using Auto ISO.

The screen moves in every direction

Another significant improvement that Canon has made to one of its dual-grip cameras is the addition of a back display that can be moved. It is a side-hinged, fully articulated touchscreen, which instantly makes the R3 a more practical video camera than any 1D-series camera. This is accomplished simply by providing the option to cradle the camera at waist height, as opposed to having to try to steadily hold a large camera at arm’s length.

Also, the panel looks quite great. The resolution of 4.15 million dots (1440 x 960 pixels) on a camera is the greatest that we have seen so far.

A hot-shoe equipped with an interface.

The EOS R3 receives a number of communication pins along the leading edge of its hot shoe. This ensures that the camera is still compatible with previously released Speedlites, but in addition, it now has the capacity to accept a number of different accessories. TEAC has already made an announcement on the first of them, which is the launch of their Tascam XLR microphone input module.

Even when a flash that isn’t sealed is mounted to the camera, the hot shoe mount is engineered to ensure that the body remains hermetically sealed. It is rather amusing that if you wish to attach a splash- and drip-proof Speedlite to the R3, you will need to utilize an AD-E1 adapter. This is because the locking mechanism might potentially damage the hot shoe if it comes into contact with it.

Storage and batteries

The Canon EOS-1D R3 utilizes the same LP-E19 battery that is found in the Canon EOS-1D X Mark III, continuing the imitation of an EOS-1D camera down to the component level of the battery. It is also compatible with the older LP-E4N batteries, although it is not suggested to charge E4N batteries with the charger that comes with the R3. However, it is compatible with the earlier LP-EP4 batteries.

When using the viewfinder, the LP-E19 is rated to give 440 shots on each charge, whilst the back screen is rated to deliver 760 shots per charge in the quicker refresh’smooth’ mode. The LP-E19 is a hefty device that has a capacity of 30Wh. When you switch to power-saving mode, these statistics increase to a maximum of 860 and 620 photos per charge, respectively.

The statistics that are produced from the CIPA Standard test always have a little chance of underestimating the performance in the actual world. In normal day-to-day use, it is not at all unusual to acquire more than double the number of shots that are rated for the firearm.

In spite of this, the fact that the more responsive viewfinder mode only allows for 440 photos per charge is perhaps something that professional sports photographers are concerned about. Even if taking photos one at a time is often more time-efficient than taking photos in bursts, a rating of 440 shots is shockingly low for a professional-grade camera with such a sizable battery.


The EOS R3 is identical to the EOS R5 in that it has both a slot for a CFexpress Type B card and a slot for an SD card of the UHS-II type. This affords you the benefit of flexibility and increases the likelihood that you will have a card that is compatible on hand. However, it’s also possible that it means the write rates aren’t compatible, which might limit what you can do while taking video and cause the camera to operate more slowly if you shoot to both slots at the same time.

Final Verdict

The Canon EOS R3 is the best camera option available from Canon for capturing a wide variety of themes, including sports, action, photojournalism, wildlife, and a lot more. This camera excels when directed at things that are moving quickly and is an excellent choice for high-end photographers as well as those who are interested in becoming high-end photographers.

It is becoming increasingly impossible to be content with the newly discovered annoyances (extra steps or efforts necessary to get the same work done) of the older versions of high-end cameras, and the R3 highlights those shortcomings of the previous models.

The R3 boasts a build quality that is suitable for professionals, and it also includes what is likely the greatest autofocus technology that has ever been included in an interchangeable lens camera. This camera has a distinct edge over all other models in terms of review time because of its Eye Control AF, subject identification and tracking performance, Smart Controllers, and a multitude of other features.

The performance of the Canon EOS R3 is indicative of membership in the premier 1-series, and it is a simple decision to make to go with the R3 rather than the 1D X Mark III. The fact that the R3 is a model from Canon’s 3-series indicates that the company will likely release a model that is even more amazing (and more expensive) in the near future.

Pros & Cons

Good For
  • Clairvoyant mind-controlled autofocus.
  • The best in-camera stabilization I’ve ever measured using standard EF lenses without image stabilization.
  • 30 frames per second with fully automated exposure and ISO, complete lens adjustments, and autofocus that follows the subject!!!
  • I don’t detect any evidence of a rolling shutter, which is wonderful.
  • USB-C power delivery is used for charging and operation (you need a battery installed in both cases).
  • One-button voice recorder.
  • A bulb timer that allows for exposures of any length to be timed.
Need Improvement
  • The ON/OFF button is situated in an awkward location.
  • People who have tiny hands may have difficulty accessing the customized buttons on the front.
  • My R3 is having issues focusing properly with two of the three third-party lenses I have.
  • The size and cost of an item determine its place in a niche market.
