Canon EOS R3 Review

January 18, 2022 | Mark Goldstein | Rating star Rating star Rating star Rating star Half rating star


Canon recently declared that the EOS-1DX Mark III would be the last flagship DSLR camera that they ever make, as they concentrate even more fully than before on switching their camera and lens ranges over to mirrorless.

Enter stage left the new EOS R3, which despite not inheriting the "1" series denomination is still very clearly the mirrorless equivalent of last years EOS-1DX Mark III, with both very much designed to be the ultimate sports and wildlife, full-frame professional-level camera.

With the 45-megapixel EOS R5 positioned as the company's high-resolution option, the new Canon R3 instead focuses almost entirely on out-and-out speed.

It features a brand new 24.1 megapixel full-frame stacked back-illuminated CMOS sensor, up from 20 megapixels on the EOS-1DX Mark III, and the very latest DIGIC X image processor.

Burst shooting speeds are rated at 30fps continuous shooting in live view or 12fps with the mechanical shutter and the buffer allows Raw and JPEG bursts of up to 1000 frames.

The native ISO range runs from 100-102400, which can be expanded to ISO 50-204800, and the top shutter speed is 1/64,000sec when using the electronic shutter.

There is up to 8-stops of image stabilisation available via a combination of the camera's in-body Image Stabiliser which works in tandem with the attached lens’s own stabilisation system.

The brand new Eye control AF feature lets you select focus points or subjects to track simply by looking at them in the electronic viewfinder, whilst subject tracking can recognise people, animals and also now motorsport vehicles when shooting both photo and videos.

The Dual Pixel CMOS AF II system that's used when shooting video or in Live View features 4779 autofocus points with 1053 automatic positions.

The Canon R3 has a blackout-free 5,760,000-dot electronic viewfinder with 120fps refresh rate and 100 per cent coverage and a vari-angle 8.2cm, 4,200,000-dot touch-screen LCD.

It can record 6K RAW video at 60fps and up to DCI 4K/120p slow-motion video internally to a CFexpress card.

There's also dual memory card slots (CFexpress and UHS-II SD), built-in Wi-Fi, Bluetooth and GPS, and integrated USB Type-C, mini HDMI, headphone, microphone, N3 remote, and Ethernet ports.

The Canon R3's magnesium alloy body is both dust- and weather-resistant, just like the EOS-1DX Mark III, with both cameras offering the same level of weather-proofing as each other.

The new Multi-Function Shoe provides data communication and power for new accessories such as the ST-E10 Speedlite Transmitter, DM-E1D Stereo Microphone, and AD-P1 Smartphone Link Adapter, as well as acting as a traditional hotshoe for existing Speedlites and triggers via the AD-E1 Multi-Function Shoe Adapter.

The Canon EOS R3 is priced at £5879 / $5999 body only.

In terms of the R3's main rivals, they include the Sony A1, Sony A9 II and the Nikon Z9.

We've been testing a full-production EOS R3 camera for the last few weeks, paired with the 24-70mm and 70-200mm F2.8 L-series zoom lenses.

So read on for our full Canon R3 review, complete with full-size sample photos and videos for you to download and evaluate.

Ease of Use

Canon EOS R3

Against the continued backdrop of the global Coronavirus pandemic and its knock-on effects on the sporting world, Canon have released not one flagship action camera in the form of 2020's EOS-1DX Mark III DSLR, but two with the late-2021 unveiling of the EOS R3 mirrorless model.

Both of these models are specifically targeted at sports and wildlife photographers and videographers who prioritise speed of shooting and operation above all else, making the R3 a more niche proposition than, say, the EOS R5.

Viewed side-by-side, it's immediately clear that the latter owes an awful lot to the former in terms of its overall design, albeit in a significantly smaller and lighter package.

Subsequently the R3 is a lot lighter than the EOS-1DX Mark III, weighing in at 822g body-only or 1015g with both a battery and memory card fitted versus 1250/1440g respectively on the DSLR.

It's smaller too, measuring 150x 142.6 x 87.2mm versus the 158 x 168 x 83mm dimensions of the EOS-1DX Mark III.

So although both cameras share the same integrated-grip design that's long been followed by the EOS 1-DX series, the new Canon R3 is smaller, lighter and therefore more usable for longer periods as a result.

Indeed, the fact that it's virtually the same size and weight as the EOS R5 with a battery grip attached means that you should only discount the R3 if you really want the option of removing some of its bulk.

Canon EOS R3

In practice, I found it just as easy to handle for longer periods of time as any semi- or pro- camera with a battery grip attached, and being completely integrated into the overall design, there's no unwanted flex or movement that's inherent to cameras with optional battery grips attached.

Another direct benefit is that the Canon R3 benefits from having a very deep handgrip that comfortably accommodates four fingers, something that can't be said of some of its main rivals.

At the heart of the EOS R3 is a brand new 24.1 megapixel sensor with, for the first time ever on a Canon camera, a stacked design that has been developed exclusively by Canon.

This allows you to use the R3's electronic shutter to freeze fast movement without worrying about rolling shutter distortion whilst enjoying a black-out free , 5.76m-dot OLED, 0.76x-magnification electronic viewfinder that refreshes at 120fps, perfect for tracking your subject whilst shooting at up to 30fps.

Sony users have of course enjoyed the benefits of a stacked design for several years now, since the launch of the original Alpha 9 in 2017, so it's great to see Canon catching up with one of their main rivals.

The magnesium alloy bodied 24.1MP Canon EOS R3 has an overhauled AF system and sensor that offer even better AF tracking performance, image quality and communication capabilities than the 1-DX series.

Starting with the headline-grabbing continuous shooting speeds, that's certainly true when taking advantage of the silent electronic shutter, which ups the ante from 20fps on the EOS-1DX III to a blistering 30fps on the new EOS R3, complete with full AF and AE tracking.

Canon EOS R3

The buffer "only" allows Raw and JPEG bursts of up to 540 JPEG or 150 RAW frames when using the electronic shutter, though, which is significantly less than the 1000+ JPEG or 1000 RAW images that is achievable when using the mechanical shutter.

That's not quite the full story, however, as the EOS R3 can only shoot at 12fps with the mechanical shutter, a much slower rate than both the 30fps electronic mode and the EOS-1DX III's equivalent 16fps rate.

Still, being able to continuously shoot 5 seconds of 24 megapixel RAW files at 30fps or 18 seconds of full-sized JPEG files at the same rate using a completely silent shutter should certainly please all but the pickiest of customers.

To cope with modern data hungry demands, the camera uses the latest generation CFexpress memory card format, which boasts a write speed over 3x that of the previous swiftest CFast cards.

Unlike the EOS-1DX Mark III, though, the EOS R3 doesn't just use that media format alone, with the second card slot reserved instead for UHS-II SD cards.

While that greatly expands the choice of memory cards that can be used with this camera, we suspect that the majority of owners would have preferred dual CFexpress slots instead of the mixed approach, as burst shooting speeds are much slower when recording to SD cards.

It's no use having all of that raw speed at our fingertips however if the camera falls down in other respects. Battery life is, however, fortunately as robust as the camera's outer shell.

Canon EOS R3

With the same rechargeable LP-E19 cell as used by the EOS-1DX Mark III inserted, it's claimed that 860 shots maximum are achievable from a full charge when using the LCD screen and 620 when using the electronic viewfinder.

Both of these don't compare all that well with the whopping 2850 battery life offered by the EOS-1DX Mark III, but that is only applicable when using the optical viewfinder.

Even if users are shooting mainly in the EOS R3's 30fps burst mode, it will still take some time rattle through its battery life, as the quoted CIPA figures are very conservative. Plus you can always pack a spare battery or three if heading out for the day or as back-up when covering a major event.

So the Canon R3 is very quick and robustly manufactured - but what about video? That particular box is ticked via the offering of up to DCI 4K-resolution clips at up to 120fps, with 6K Raw recording also on hand.

Unlike the EOS-1DX Mark III, which was somewhat hampered by the need to focus manually rather than relying on AF when shooting at a faster frame rate than 30fps, the new mirrorless R3 supports full-time AF and AE metering at all available frame rates.

Additionally, whereas the EOS-1DX Mark III only offered digital image stabilisation for both stills and movies, the R3's incredible in-body five-axis image stabilisation system offers up to 8 stops of compensation when paired with certain RF lenses that also have their own built-in IS.

In-body stabilisation is one of the key benefits of mirrorless versus DSLRs in general and also one of the key reasons to choose the R3 over the EOS-1DX Mark III.

Canon EOS R3

It has been designed to work collaboratively with the IS system that's built into many RF-mount lenses, with the lens and the sensor working together to correct pitch and yaw and the sensor correcting the X-Y and roll movements.

This intelligent stabilisation system provides a frankly incredible 8-stops of stabilisation with some lenses, allowing you to hand-hold the camera for up to 4 seconds and still get critically sharp results.

Even some non-stabilised lenses such as the RF 85mm F1.2L USM or RF 28-70mm F2L USM offer 8 stops of stabilisation when they're mounted on the EOS R3, thanks to the large 54mm diameter of the of the RF Mount.

The EOS R3 can also stabilise older, non-IS lenses including any EF lens that is mounted on it via the Canon EF-EOS R mount adapter.

The stabilisation system will also work with lenses from other manufacturers – you just need to input the focal length into the camera's menu system.

In practice, the EOS R3 stabilisation system is excellent, making it possible to hand-hold the camera at previously impossibly slow shutter speeds and still maintain critical sharpness.

The Canon R3 features the next generation Dual Pixel CMOS AF II focusing system. Billed as the world’s fastest AF, the camera is capable of focusing in as little as 0.03 seconds.

Canon EOS R3

It has 4,779 selectable AF points, which is slightly less than the EOS R6 and R5, with the same 100% frame coverage in Auto selection mode and 90% vertical in manual selection.

Impressively the EOS R3 can also focus in light levels as low as -7.5EV (when used with an F1.2 lens), the best of any current Canon mirrorless camera.

Thanks to its Digic X processor, the EOS R3 offers the same deep-learning artificial intelligence based automatic face, eye and animal AF tracking modes as the R5 and R6 models.

The Canon R3 can recognise and track eyes from much further away than previous models, and it works even if the person is wearing a mask, helmet or sunglasses. Subject tracking works for humans and also dogs, cats and birds, the latter even in flight.

Brand new to just the EOS R3 is the ability to track vehicles, including cars and motorbikes. What's more, if the driver is wearing a helmet, the AF system will lock on to that, ensuring that the most important subject is in focus.

Although we didn't get the opportunity to attend an actual motorsports race, we did shoot several 30fps sequences of a fast-moving motorbike driver and the EOS R3 instantly and consistently locked onto his helmet and tracked him across the frame, with every single shot in focus. Impressive stuff.

As well as the expansion of recognised subjects, Canon have also further improved their AF system with the introduction of Eye Control autofocus technology.

Canon EOS R3

You can now select an AF point, or a specific subject to track, simply by looking at it! Half-pressing the shutter button then either focuses at the selected AF point or starts continuously tracking the chosen subject.

The camera can be calibrated for different photographers or for the same photographer wearing either spectacles or contact lenses and claibration settings can be saved and even swapped between cameras via a memory card.

Eye Control AF sounds a little gimmicky at first, but in practice it's both easy to calibrate and easy to use, quickly and seamlessly focusing wherever to look in the frame, with the Set button by default used to toggle it on and off.

The only thing that slows things down a little is the requirement to half-press the shuter release button to effectively confirm the AF point or subject - with some high-speed cases having to do this could make the difference between capturing a very precise moment or missing it.

It would be great if Canon could provide the option to immediately start Servo AF when usinmg Eye Control AF without the half-shutter press being required.

Still, for most use cases Eye Control AF is a genuinely eye-opening addition (excuse the pun) to what is already a superb auto-focus system, and one which we hope and expect Canon will implement in future EOS mirrorless cameras.

For shooting at night or in low light, users get incrementally selectable sensitivity settings running from an expanded ISO 50 to ISO 204,800, selected via the rear command dial, with a familiar LCD window on the top plate detailing the selection made.

Canon EOS R3

That's an impressively broad selection, especially as images at the boosted settings are still usable, something that couldn't be said about the EOS-1DX Mark III even faster ISO 409,600 and 819,200 settings, unless you were happy with something that more closely resembled a brass rubbing than a photo as such.

File format wise, the Mark III is also Canon's latest EOS camera to support the ‘next generation' HEIF (High Efficiency Image File) file format, enabling images with 10-bits of data to be saved in a file the equivalent size of a JPEG, while suffering less compression.

Of course Raw files can be shot in tandem with JPEGs (or indeed HEIF files) as per usual - here with Canon's own .CR3 (Canon Raw) file extension, which requires the likes of Photoshop or Lightroom to access and open.

It's also the latest model to have built-in Wi-Fi (5 GHz and 2.4 GHz)) and Bluetooth 5.0, there is a built-in GPS module which is compatible with GLONASS and QZSS and it also features a 1000BASE-T Ethernet interface and RJ-45 port for a fast and secure hardwired connection.

For video specialists it boasts 6K/60p 12-bit Raw video internal recording to a CFexpress card, making it the first non-cinema Canon EOS camera to offer that feature.

There's also uncropped 4K DCI and UHD 10-bit recording at frame rates between 24 and 120fps in the MP4 format,, with Canon Log 3 available, both produced by oversampling the sensor’s 6K native output. Slow-motion movies (without sound) can be captured at 120p/100p at 4K and HD resolutions.

All-I, IPB, and IPB Light compression options are available and HDR-PQ recording is supported for even greater highlight and shadow detail.

Canon EOS R3

The R3 supports unlimited recording times with no overheating, allowing up to six hours of normal video or 90 minutes of full HD high frame-rate footage to be captured, and it features mic and headphone ports and a micro-HDMI Type-D port for output to an external recorder.

The EOS-1D X Mark III had several buttons which could be illuminated if its display light button was pressed, allowing for users to better identify functions if working in near dark conditions. Sadly the new EOS R3 doesn't inherit this useful feature.

Taking the camera out of its box and affixing one of the two lenses that came with our review sample - an RF 24-70mm f/2.8L IS USM and RF 70-200mm f/2.8L IS USM - it's immediately apparent that this is a large and not particularly discrete camera setup.

The minimalist front plate houses two controls that are additionally mirrored for portrait use. The top one instantly engages the camera's AF tracking system, and the bottom one is an unmarked Function button that can be customised. By default it activates the classic Depth of Field preview function, which helps you determine what your photos will look like before the image is taken.

There's also a rubber flap that covers the N3-type socket for a remote switch at the bottom-right corner of the front of the camera, along with a porthole for the AF assist light and a lozenge shaped button for releasing the lens.

What we personally and also immediately missed here, compared to most pro and semi pro cameras, was a large, chunky tactile shooting mode wheel or dial to the left or right of the viewfinder.

Even if the shooting mode can be rapidly - and as it turns out, fairly conveniently - accessed via a press of the Mode button on top of the camera, just like on the EOS R5, we'd still prefer a more traditional dial.

Canon EOS R3

The lack of a familiar shooting mode dial is equally true of all the generations of the EOS-1D X, including the latest Mark III, but to somebody used to handling a wide variety of cameras, its omission initially feels a little odd until you get used to the camera's operability.

The main advantage of the EOS R3's approach is being able to quickly see the current camera settings by simply glancing down at the top-plate LCD.

It provides quick and easy viewing access to most of the camera's key settings, with the dedicated button alongside it toggling between two different screens of information and also allowing it to be lit up in the dark via a longer press - very neat.

The EOS R3 does depart from the blueprint of its DSLR-equivalent by offering a fully articulating, vari-angle LCD screen, whereas the LCD screen on the EOS-1D X III is of the fixed, non-tilting variety.

An angle adjustable LCD is much more useful if you're going to be shooting video in the main, as it's tricky to be 100% certain you've got focus spot on when using a fixed screen outdoors; inevitably glare and natural reflections sometimes get in the way.

On the other hand, given that this is the sort of professional tool that will be used in spaces where it could get knocked and elbowed by competing photographers, a fixed screen is undoubtedly a wise decision, even if it makes video shooting without some sort of external monitor trickier than it could be.

We did however appreciate the fact that key shooting settings on both cameras can be implemented and accessed with a finger tap on-the-fly on the touchscreen LCD.

Canon EOS R3

The EOS R3 has a very well-specced 3.2-inch, 4.15 million dot, vari-angle LCD screen which tilts out to the side and faces forwards for more convenient vlogging and video recording.

It can also be usefully folded flat against the back of the camera to protect it when in transit in a camera bag.

A proximity sensor is located directly beneath the viewfinder, which automatically switches between the EVF and LCD screen. When the LCD screen is swung outwards, the EVF is cleverly turned off automatically.

A tilting LCD screen always helps to encourage shooting from creative angles and it also helps make the EOS R3 ideally suited to movie-shooting.

As mentioned above, the LCD screen is touch-sensitive, allowing you to control everything from setting the AF point and firing the shutter, navigating the menu systems and browsing your images during playback. It's a very precise, responsive system that's a veritable joy to use.

Although like any pro-level camera there are plentiful buttons and controls, ultimately the EOS R3 is only as complicated as you yourself want to make it.

Once you've set the basics of image quality, file format/s and whether you want to shoot in single shot or continuous mode - away you go - though the positioning of the power lever at the bottom right of the camera back, where it falls under your thumb rather than encircling the shutter release button - of which there are two, dependent on whether you want to shoot in landscape or portrait fashion - initially throws up something of a curve-ball.

Canon EOS R3

The EOS R3 doesn't inherit the EOS-1D X III's second smaller LCD immediately beneath the main LCD screen, on which the file format/s you're shooting in are displayed. This is shame, but eminently understandable given the smaller dimensions of the R3 compared to its even bigger brother.

Conveniently placed below the LCD screen are a row of three buttons, clearly marked for accessing playback, enlarging an image so focus can be checked, and deleting images.

The Menu and Rate buttons meanwhile are placed immediately left of the viewfinder window where they can be accessed via the thumb of the left hand when gripping the camera, so the user doesn't have to take their away from the viewfinder for long and possibly miss the subject matter.

Operationally we flitted between using the joystick-like multi controllers and main and quick control dials for either tabbing gingerly or racing through prospective settings, respectively. If turning the camera on its side to shoot portrait fashion, we also handily get a third dial on the vertical grip.

We're practically falling over buttons and dials on this camera, but with the added convenience of alternatively tapping the LCD screen for key settings when it makes sense to do so. The overall effect is that operation is sped up, which is exactly what we'd want from a camera of this ilk.

So what about image quality? Do the pictures live up to what we'd hope for and indeed expect from a near £6K camera body? Carry on reading our Image Quality section to find out.

Image Quality

All of the sample images in this review were taken using the 24 megapixel JPEG setting, which produces an average image size of around 12Mb.

The Canon EOS R3 produced still images of outstanding quality during the review period.

This camera produces noise-free JPEG images from ISO 50 all the way up to ISO 6400, with noise first appearing at ISO 12800. The faster settings of 51200 and 102400 display quite a lot of noise, but they're still fine to use for making smaller prints and web images. Even the fastest expanded setting of ISO 204800 can be used at a push.

The EOS R3 proved to very capable in low-light, with the maximum shutter speed of 30 seconds and the Bulb mode allowing you to capture enough light in all situations and the camera's incredible -7.5EV rating successfully auto-focusing even in virtually dark conditions.

The different Picture Styles and the ability to create your own are a real benefit, as are the HDR settings and multiple exposure mode, all of which can be previewed before you take the shot. Support for the new HEIF 10-bit file format is a little thin on the ground, but should offer a degree of future-proofing.


ISO sensitivity can be set between ISO 50 and ISO 204800 in full-stop increments. Here are some 100% crops which show the noise levels for each ISO setting, with JPEG on the left and RAW on the right.

The Canon EOS R3's maximum shutter speed is 30 seconds and there's a Bulb mode for even longer exposures, which is excellent news if you're seriously interested in low light photography.



The Canon EOS R3's HDR Mode captures three different exposures and combines them into one, retaining more shadow and highlight detail, with an Auto mode, and three different strengths. There's also a special HDR PQ mode which automatically records in the HEIF file format.








HDR PQ (HEIF Format)

Multiple Exposure

The EOS R3's multiple exposure mode allows you to take between two and nine images and merge them into a single photo in-camera.


Picture Styles

Canon's Picture Controls are preset combinations of different sharpness, contrast, saturation and colour tone settings. The EOS R3's seven available Picture Controls are shown below in the following series, which demonstrates the differences. There are also three User Defined styes so that you can create your own particular look.

The new Canon EOS R3 combines the familiar blueprint of the 1D-X series with all the benefits of mirrorless to create a truly remarkable camera for professional sports and wildlife photographers and videographers alike.

Long revered as the pinnacle of Canon's technological prowess, the EOS-1DX Mark III DSLR has now been surpassed by the EOS R3 as the company's go-to camera for almost anything that moves quickly - people, animals, birds, vehicles - you name it and this camera can intuitively and almost instantly capture it with the absolute minimum of fuss.

Not only has the range of recognised subjects been expanded, but the way in which you can focus on them has been further improved with the addition of Eye Control AF, a feature that at first sounds like a gimmick but in practice soon becomes a seamless part of how you use the camera.

Other key advantages that the EOS R3 has over its DSLR sibling are the incredible hybrid image stabilisation worth up to 8-stops, superlative low-light AF sensitivity that stretches all the way down to -7.5EV, and the even faster headline-grabbing 30fps burst shooting, coupled with a completely silent electronic shutter.

This is all housed in a smaller, lighter yet still equally weather-proof and durable body that's easier to use for extended periods of time.

There's an awful lot to like about the EOS 3 and very little to grumble about. Sure, the integrated grip design certainly isn't for everyone - at just over 1kg in weight it remains a camera for the professional rather than enthusiast, although we bet that many of the latter would enjoy using the R3, particularly if they routinely fit a battery grip to their current camera.

Some users will prefer a camera with more megapixels than the 24 offered by this camera, but Canon already have the 45 megapixel R5 model that's already proved incredibly popular, especially as it also ups the ante on the video side of things with 8K recording.

The decision to specify mixed media memory card slots is a little mystifying on such an expensive, all action device - we'd have preferred the R3 to follow the EOS-1DX Mark III's lead by using 2x CFexpress cards instead of the secondary UHS-II SD card slot.

Battery life is also greatly reduced when comparing these two flagship models, but that's more a limitation of mirrorless versus DSLR rather than a direct criticism of the R3 itself.

The Sony A1 and the Nikon Z9 are the only other full-frame cameras that can shoot at 30fps, but the former is limited to shooting lossless compressed and the latter can only shoot JPEGs, leaving the R3 as the only model able to achieve 30fps with no limitations on the file format. On the other hand, the Alpha A1 and Z9 both offer a lot more resolution (50 and 45 megapixels respectively) than the EOS R3, and both can record 8K video too.

Eagle-eyed readers will surely have noticed by this point of our review that Canon's new sports camera doesn't actually inherit the 1-series moniker - that has seemingly been reserved by the upcoming EOS R1, which will presumably be a higher-resolution rival to the Z9 and Alpha 1.

Still, at the end of the day, it's not all about specs, despite the often forensic internet focus on them. The new Canon EOS R3 is a compelling camera for action shooters, stills and video alike, which inherits the prestigious mantle of the 1D-X series and improves on it in many, often surprising ways...

Canon UK Press Release 14/09/2021

The wait is over – Canon’s new sports hero is here to outpace and outperform

London, United Kingdom, 14th September 2021 – Canon Europe today announces the highly anticipated EOS R3 – a powerhouse for sports photography and reportage. Blending tradition with cutting edge technology, the EOS R3 offers all the familiarity and speed of Canon’s renowned EOS-1 series, with the innovation and versatility of the pioneering EOS R System.

Designed using feedback from the most demanding professional press and sports photographers, the EOS R3 features over 100 improvements upon Canon’s mirrorless and DSLR models. The result is a camera which dramatically streamlines workflows and takes the connection between camera and photographer to new levels, for unbeatable speed and responsiveness. With a brand new, innovative 24.1 megapixel sensor, the EOS R3 gives the optimal balance of performance, resolution and speed to offer news and sports photographers a camera to outperform and outpace the competition.

The future is fast

Leveraging the ground-breaking new 24.1 megapixel backside illuminated stacked CMOS sensor, the EOS R3 offers lightning fast image capture and enhanced responsiveness. The powerful sensor almost entirely eliminates rolling shutter distortion and with a rapid shutter speed, offering a range of 30 seconds to 1/64000th of a second, it helps sports photographers freeze the fastest of subjects. When using the electronic shutter, photographers can shoot up to 30fps with AE and AF tracking even when shooting RAW files, as well as options for shooting at 15fps and 3fps. The electronic shutter can also be used with both Canon and third-party flashes for the first time. Removing the traditional weaknesses of electronic shutters, Canon has introduced Flicker detection and a High Frequency anti-flicker shooting mode to detect and correct flickering light sources and prevent banding or colour and exposure issues.

The EOS R3’s high speed performance does not stop at the frames per second, it extends to the focusing as well. Capable of focusing in 0.03 seconds, the EOS R3 is the fastest EOS R series camera yet – perfect for capturing the unpredictable action of sport and reportage. Powered by Dual Pixel CMOS AF II, the EOS R3 features an improved Deep Learning algorithm, offering AF tracking including human and animal eye, body, and face detection as well as head detection for humans in both stills and videos. Designed with motorsports photographers in mind, Canon has also introduced a vehicle tracking function, to expertly track motorbikes, open cockpit Formula cars as well as GT and rally cars – with the ability to prioritise the vehicle or the driver’s helmet. Eye, face, head and body detection are now available in all AF modes, as well as a new Flexible Zone allowing users to select the size and shape of the Zone AF area. The EOS R3 sets a new standard for its ability to focus in lighting conditions as low as -7.5 EV - making this one of the most capable low light cameras available.

To maximise control over all these AF options the EOS R3 offers three different ways to select the AF points: the quick smart controller, the precise multi controller and the instinctive Eye Control AF. Eye control AF provides a more natural connection between the camera and the photographer. This intuitive and pioneering AF point selection method moves the focus point to where the photographer looks. In situations where the story can quickly unfold, this allows photographers to instinctively focus on the action with just a look.

Enhancing the ability for handheld shooting and steady movie production on the move, the 5-axis In-Body Image Stabilizer can combine with optical Image Stabilizer in selected RF lenses and offers industry-leading performance with up to 8-stops.

Outpace your peers

For professional photographers shooting in the field, it’s not just about the speed of capturing a moment but also the speed of getting it to the news desks and editors that matters. With a number of professional connectivity options including built in version 5.0 Bluetooth and 5 GHz Wi-Fi, the EOS R3 streamlines workflows and simplifies the connection to a smartphone or Wi-Fi network. Ideal for sport arenas, the built in Gigabit Ethernet port enables a high speed wired connection. And, for when speed really matters, photographers can transmit images to clients via FTP. For existing EOS R5 and EOS-1D X Mark III users, network settings can be shared between the three cameras.

Users can remotely control the camera from a mobile device using the Canon’s Camera Connect App or using the Browser Remote function via an ethernet connection. A popular feature from the EOS-1D X Mark III, the Browser Remote function also enables users and head offices to remotely change metadata, browse and download images. Users will also be able to use Canon’s Mobile File Transfer (MFT) app - a mobile application for professional photographers that transfers images over a mobile device to an FTP/FTPS/SFTP server. Future enhancements of the app will include text conversion of voice memo, enhancing ease of use for professionals. A new smartphone holder accessory for the EOS R3, the Smartphone Link AD-P1, allows users to mount their iOS or Android device on top of the Multi-Function Shoe Adapter and easily transmit images via the new MFT app . The Canon Camera Connect app now enables the EOS R3 firmware to be updated via your phone - a first for an EOS camera.

Incredible video capabilities

As with the EOS R5, the EOS R3 takes Canon’s hybrid offering to the next level – meeting the demand for photographers to capture the action in both high-quality stills, and impressive high-resolution video. It offers powerful video capability, capturing 6K 60p RAW resolution footage, which offers 50 per cent more detail than 4K. With 6K CRM RAW files, exposure and white balance can be corrected post capture to ensure stunning image reproduction. 4K footage up to 60p is oversampled from 6K guaranteeing the highest possible 4K movie quality. Great for high speed and dynamic sports, the EOS R3 captures 4K 120p footage for stunning 4K resolution slow motion. It’s now possible to record up to six hours of regular video or 1.5 hours at high 119.88/100p frame rates.

At its core, the EOS R3 is designed to help photographers outpace their competitors – and the same is true for video. To reduce the file size and speed up video workflows, CRM light or MP4 footage can be recorded in All-I, IPB or the smaller IPB light option, allowing users to select from a range of bit rates to meet their needs and storage requirements. Dual card slots, including a UHS-II SD card slot and the ultra-high speed CFexpress make shooting 6K RAW video possible and support simultaneous recording to both cards in MP4 , providing a fail-safe back up of vital footage. Canon’s renowned Canon LOG 3 enables 10-bit internal recording, to achieve a greater dynamic range or 10bit HDR PQ which minimises the need for editing or grading footage in post-production. Excellent for roving reporters, the EOS R3 features Canon’s new Multi-Function Shoe and is compatible with the newly launched Directional Stereo Microphone DM-E1D - a camera-powered directional stereo microphone using digital processing - and the TEAC Tascam CA-XLR2d-C XLR adapter which enables two channel recording with professional XLR microphones.

Instinctive shooting experience

Offering all the speed and familiarity of the EOS-1 series, Canon’s latest mirrorless employs a new Canon developed blackout-free, high-quality 5.76 million dot electronic viewfinder with low lag and refresh rate of up to 120 fps at full resolution for a viewing experience that rivals an optical viewfinder. Along with the newly introduced OVF simulation View Assist, the viewfinder offers richer tones and greater dynamic range. The shutter lag can be reduced to an astonishing 20ms - less than half that of a conventional camera, for near instant capture when the shutter release is pressed. The new high resolution Vari-Angle 4.1-million dot touch screen provides more detail than ever before and offers greater flexibility of shooting angles thanks to its ability to tilt and rotate into a range of positions. Combining existing EOS ergonomics with new controls and a number of new customisation options for users, including shutter sounds with volume control, the EOS R3 provides familiar, yet advanced control. To save time when moving between camera bodies, photographers can easily copy and save personalised settings to memory cards. Using the same LP-E19 battery as the EOS-1D X Mark II and EOS-1D X Mark III, the EOS R3 enables extended shooting and greater compatibility with existing DSLRs.

The EOS R3 employs a new lightweight, dust and water-resistant magnesium body for use in harsh conditions. Weather resistance can be also maintained when using existing Speedlites, by connecting them to the newly announced Multi-Function Shoe Adapter AD-E1. The EOS R3 also powers the new, compact Speedlite Transmitter ST-E10 through the Multi-Function Shoe, which gives photographers the ability to remotely control multiple radio Speedlites.

The EOS R3 is an ultra-fast, highly responsive camera that gives sports and news photographers the competitive advantage they need to get the winning shot.

Hands On

Are you excited about the upcoming Canon EOS R3 full frame mirrorless camera? Do you want to see some actual up close and personal shots of a real life model, rather than just Canon's official rendered product images?

Then you've come to the right place, as last week I was given an exclusive one-to-one briefing by Canon and had the chance to shoot an extensive gallery of hands-on photos of the R3.

As this is still an early tech announcement, though, to be more precise they were strictly hands-off photos, as I wasn't allowed to actually touch the camera, turn it on, open any of the ports or compartments, or see the bottom of it.

Canon's Product Intelligence Consultant, David Parry, was also under strict orders not to divulge any additional information about the EOS R3 other than what has already been revealed in the previous two press releases that Canon have issued. So I'm afraid I don't have any more information for you about the megapixel count of the sensor, for example, or whether it will be able to record 8K or just 4K video.

Canon did a similar thing for the EOS R5 camera in 2020, where they showed me an early pre-production model well ahead of the official launch that turned out to be virtually identical to the finished article. So if they follow the same plan for the R3, the photos that you see here will be almost 100% the same as the actual camera that will be available to buy later in 2021.

So without further ado, here is our extensive gallery of hands-on photos of the exciting new Canon EOS R3 full-frame mirrorless camera.

Please note that if you would like to re-publish any of the images included in this Canon EOS R3 Hands-on Photos article, you may only use up to 5 images without prior permission. Please also include a link back to the original article. Thank you.
