Built for speed, versatility, and reliability, the Canon EOS R3 combines technology from their mirrorless EOS R system with the robustness and performance you'd expect from a flagship DSLR. Revolving around a new full-frame stacked sensor, updated AF performance, and a refined body design, the EOS R3 is the first 3-Series camera since the film era and plants itself as a fast-shooting, flexible, and contemporary mirrorless camera.

Among the most significant technologies in the R3 is the 24.1MP stacked sensor which affords truly fast readout speeds to help reduce rolling shutter distortion and benefit fast continuous shooting and video recording applications. This full-frame BSI CMOS sensor has an updated DIGIC X processor, which helps boost the overall speed for up to 30 fps continuous shooting with an electronic shutter, 6K 60p raw and 4K 120p video recording, plus intelligent Dual Pixel CMOS II autofocus with Eye Control AF for intuitive focus point selection.

The R3 is also the first EOS R-series camera to feature a built-in vertical grip, making it an ergonomic choice for long shooting times and for seamlessly switching between horizontal and vertical shooting orientations. The rugged body design also incorporates a high-resolution 5.76m-dot OLED EVF and a 3.2" vari-angle touchscreen LCD, along with dual memory card slots, wireless and wired connectivity, and an updated Multi-Function Shoe design for expanded accessory compatibility.

Full-Frame Stacked Sensor and DIGIC X Processor
24.1MP BSI Stacked CMOS Sensor
A first for EOS cameras, the R3 features a stacked sensor design that promotes impressively fast read-out speeds to greatly reduce rolling shutter distortion and enable faster shooting performance. This 24.1MP full-frame CMOS chip also has a back-illuminated design that is more efficient at gathering light, which leads to reduced noise, higher clarity, and smoother color rendering, particularly when working in low-light conditions.
DIGIC X Processor
An updated DIGIC X complements the new sensor design with capable processing and the ability to perform simultaneous high-speed tasks, such as 30 fps high-speed shooting while performing AF and AE readings before each frame. The processor also helps to realize a broad sensitivity range from ISO 100-102400, which is expandable to ISO 50-204800, for working in a broad variety of lighting conditions.
Electronic Shutter
A main benefit of the stacked sensor design is a highly usable electronic shutter function that is able to shoot continuously at up to 30 fps, for up to 150 raw frames, with virtually no rolling shutter distortion. When working in manual or shutter-priority modes, the top shutter speed is 1/64,000 sec and flash sync is even possible with an electronic shutter, up to 1/180 sec. This versatile shutter function is inherently silent, but can be paired with a choice of audible shutter noises to go along with each shutter click to make it easier for subjects to recognize when a photo has been taken.

A manual shutter is also available, and offers a top continuous shooting speed of 12 fps, with a buffer of more than 1000 frames, along with a top flash sync speed of 1/250 sec.
6K Raw and DCI/UHD 4K Video Recording
Also contributing to notable video performance, the 24MP full-frame sensor offers high-res 6K raw 12-bit internal recording and uncropped 4K 120p 10-bit recording with Canon Log 3. Both 6K and 5.6K recording areas can also be used for oversampled DCI and UHD 4K shooting with improved sharpness, reduced moiré, and lower noise. HDR-PQ recording is possible, too, for in-camera HDR production and external recording, via the HDMI port supports a clean 4K output at up to 60 fps. All-I, IPB, and IPB Light compression options are available, along with the ability to use Dual Pixel CMOS AF II when shooting at up to 6K raw. Unlimited recording times are possible, too, and the R3 features both mic and headphone ports, as well as a micro-HDMI Type-D port for clean output to an external recorder.
Autofocus and Image Stabilization
Dual Pixel CMOS AF II
An improved Dual Pixel CMOS AF II system features 1053 automatic AF points, which cover the entire sensor area, for faster, more responsive, and more precise focusing performance. This upgraded phase-detection focusing system also has enhanced subject detection and tracking, with the ability to intelligently recognize eyes, faces, heads (including helmets), animals, and vehicles and tracking will automatically lock onto these subjects and maintain sharp focus throughout burst captures. Dual Pixel AF II's low-luminance limit has also been improved to focus down to an impressive -7.5 EV for accurate focusing even at night.
Eye Control AF
New to EOS digital cameras, Canon is re-introducing Eye Control AF with the R3. This popular feature from the film era has now been refined and tuned to work in conjunction with Dual Pixel CMOS AF's intelligent focusing capabilities. Eye Control AF essentially allows shooters to use their eye to initiate where the focus point is simply by looking through the electronic viewfinder, and then the camera will take control using subject tracking and detection to keep the sighted subject in sharp focus.
Sensor-Shift Image Stabilizer
An In-Body Image Stabilizer (IBIS) corrects unwanted camera shake when shooting handheld, helping to shoot handheld in low-light conditions and reduce shake when recording videos. This 5-axis system can be also used in conjunction with lenses featuring optical image stabilization to compensate for up to 8 stops of camera shake depending on the specific lens in use.
Body Design
5.76m-Dot EVF and Vari-Angle Touchscreen LCD
An impressive 5.76m-dot OLED electronic viewfinder is featured for clear, high-resolution eye-level viewing. This 0.76x-magnification finder is benefitted by the stacked sensor design, too, and affords blackout free viewing when working with an electronic shutter and supports a 120-fps refresh rate for realistic motion portrayal. The large area of the viewfinder also permits displaying extensive shooting information, if desired, and the information display rotates with the camera for more natural viewing.

In addition to the EVF, a 3.2" vari-angle LCD is also available and benefits working high, low, and front-facing angles. The flexible position is complemented by a touchscreen interface and the impressive 4.15m-dot resolution allows for vivid playback and live view monitoring.
Professional-Grade Body Construction
Taking after flagship DSLR designs, the R3 sports a robust and ergonomic body design fit with an integrated vertical grip for improved comfort when working in either horizontal or vertical shooting orientations. The R3 features both the smart controller and multi-controller from previous EOS cameras, making for an intuitive handling experience, and it has a similar rear layout to the 1D X Mark III and R5 bodies. This larger body design also makes room for the high-capacity LP-E19 battery for extended shooting sessions and is built to the same weather-sealed specifications as the flagship EOS-1D X Mark III.
Dual Memory Card Slots
The EOS R3 has dual card memory card slots—one CFexpress Type B slot and one UHS-II SD slot—for file-saving flexibility. The CFexpress Type B slot should be prioritized for 6K video recording and fast continuous shooting, and the SD slot is a convenient alternative for backups or less speed-critical shooting.
Extensive wired and wireless connectivity options are available, allowing for multiple methods of transferring photos, videos, and voice memo data. Physically, the camera features a 1000BASE-T Ethernet interface and RJ-45 port for a fast and secure hardwired connection. When transferring wirelessly, 5GHz Wi-Fi and Bluetooth is available for transferring and remote camera control. Users of select smartphones can also make use of their device's mobile data for sharing files directly from the camera over 5G networks when the device is connected to the R3 via USB.

There is also a built-in GPS module, which is compatible with GLONASS and QZSS, for in-camera location tagging to help streamline any geotagging and timestamp needs.
Next-Generation Multi-Function Shoe
An update to a conventional hot shoe, the Multi-Function Shoe adds a row of pins at the front of the design to permit greater accessory functionality as well as provide power to select accessory types that traditionally rely on separate batteries. This updated shoe is compatible with select accessories, including the ST-E10 Speedlite Transmitter, DM-E1D Stereo Microphone, and AD-P1 Smartphone Link Adapter, as well as the AD-E1 Multi-Function Shoe Adapter to provide compatibility with legacy shoe-mounted accessories.
Firmware Version 1.1.1, Released Feb 2022
Firmware Version 1.1.1 is for cameras with firmware up to Version 1.0.1 If the camera's firmware is already Version 1.1.1, it is not necessary to update the firmware.
  • Adds the ability to use Smart phone link adapter AD-P1.
  • Adds the ability, when using EOS Utility or Browser Remote for remote shooting with two cards inserted, to set the recording method and select the card to be recorded to.

Canon R3 Reviews

Simply…..AWESOME !

Such an amazing camera. I’ve been shooting Canon cameras since my first SLR in 1971 — an FTb-QL that I bought in a pawn shop. I’ve progressed through MANY Canon cameras since then, but the R3 is the first new camera that has impressed me as much as this one has. The sensor is amazingly crisp and sharp; the AF options are virtually infinite, the eye-tracking is surreal; and the fit/form/function of this camera is simply stunning. Thanks again Canon, for restoring my faith in your technology.

It’s trying to do too much and missing the mark in multiple areas

By Jerritt

Had it a year now. It’s fast and when it works right it’s the best camera out there but there’s so many dumb things and issues about it. I do event photography for a major wire service. I’ve been doing it for 17yrs and never had any of the issues I have with this camera. The iso wheel moves any time the camera is on your shoulder and so when I pick it back up to shoot my iso will be on 1600 or so when I set it to 400. I can put the camera in lock mode but I change fstop sometimes in the middle of shooting a photo to give myself multiple exposures and I can’t do that when it’s locked. The focus point constantly moves on you and you have to reset it back to the middle. It’s horrible in low light with a flash. I use the EL-1. There’s no assist beam from the flash bc this camera is mirrorless and so if you’re in a dark room with minimal light as I am for many events, the camera struggles to find a focus and I have to turn the bulb on some times. If you’re shooting a full length of someone and punch in quick for a half length or headshot the focus has to be completely reset and you have to give yourself a solid second to refocus. Otherwise the camera will be focused somewhere in the background. My 1Dx Mark II has none of these issues. There’s no way to shut off the back screen when you’re in between shots so it burns battery. My 1dx screen is only on for a 1-2 second preview of whatever I just shot which this does but then this screen stays on and thinks you’re shooting in live view mode. They’re trying to cater to too many demographics with this camera. It’s a pro/amateur camera whereas cameras like the 1Dx line were strictly professional. Professional photogs don’t use swivel screens. We don’t need the extra buttons or junk. We just want a pro-line camera that only does what we tell it to do. The one plus this has over other cameras is the Retna focus. I shoot dodgers games and boxing matches in addition to events and using the Retna focus in those environments has been helpful, especially boxing where your focus point is constantly changing as the boxers rotate and move. All you have to do is look at whichever one you want in focus. I hope the R1 or whatever comes next takes care of all these issues. I haven’t bought a second R3 because of its faults. I keep my 1Dx Mark II as my second camera. That thing is a work horse.

R3 will dominate for years to come. Legendary build it just feels oh so right in your hands like a pro camera should! All the other positive reviews are spot so I won't bore you with the highlights of this camera! So if you have the dough, shoot professionally and or want the best well then, this camera will not disappoint.

Until canon does not produce the R1. The R3 has it all. 24 megapixels, but excellent image quality: color, dynamic range and more features that only this model has. Very satisfied with all the tests. In fact I have 2 R3, and an R5C, which I use for larger formats. With the R3 I cover more than 90% of my work. EXCELLENT CAMERA

Camera's definitely good but not as good as other mirrorless cameras for portrait photography, image quality is good but resolution is poor and price is super exaggerated.

Good but has room for improvement

Although I’m still getting used to the steep learning curve associated with switching from a Canon 1DX, I feel the Canon EOS R3 is a good mirrorless camera but definitely not a great camera, particularly for wildlife photography. If (hopefully when) Canon introduces a top-of-the-line EOS R1, it will include the suggestions below. Good features of the R3: 1) The size and weight of the camera is really a nice improvement over the 1DX series, although I do find myself hitting the AF-ON button unintentionally at times (it naturally falls under my thumb while holding the camera). 2) The size of the buffer is a huge improvement over the buffer sizes of the 1D and 1DX series cameras I previously owned. 3) The shutter is extremely quiet. 4) Eye tracking is amazing. Now for the bad: 1) Eye control – not a fault of the camera but since I wear eyeglasses (progressive focus lenses), eye control doesn’t work for me and I have it turned off. 2) I’d prefer a 45-50 mega pixel sensor. 3) Since I normally do not take video with the camera and save each photo to both cards, I’d prefer having CF Express Type B cards for both card slots instead of an SD card as the second slot. 4) I haven’t been able to find a way to change the set frame per second rates (fps) for the various continuous shooting rates. on the 1DX you can set the continuous shooting speed for high continuous between 2-12 fps and low continuous between 1-11. I set the low to 5 fps which is about the fastest I can shoot at to where I normally can take just 1 image if desired but can also hold down the shutter release for a continuous burst if needed. As far as I can tell with the R3 the continuous low is set to 3 fps for all drive modes and can’t be changed (nor can the other higher rates be changed except in custom high-speed continuous - see note 6 below). 5) The cover to protect the multi-function shoe is a joke (I lost mine the second time I used the camera and had to buy a spare, once it became available, that I have to tape in place to reduce the chance of it accidentally being dislodged and lost). 6) Custom high-speed continuous shooting: I’d like to see this modified so that it would work more like the Pro Capture feature that the Olympus OM-1 four thirds camera has where the camera begins recording at a user-selected rate (e.g. 30 fps) once the shutter button is pressed half-way down and saves up to a user-selected number of recorded images (e.g. up to 60 or so) when the shutter is fully depressed but doesn’t save any of the images if the shutter release is not fully depressed. Currently Canon’s custom high-speed continuous shooting allows you to set a frame rate up to 195 fps for up to 50 images that are recorded beginning when the shutter release is fully depressed. I really don’t see much of a need to take 50 images in a little over a quarter of a second (i.e. 195 fps divided by 50 images = 0.256 sec). Since I do a lot of bird photography where a bird might fly to a perch before flying to a bird feeder or water feature, I’d love to be able to begin recording the bird on the perch in anticipation of it flying to the feeder or water, tract it all the way to the feeder, and then fully depress the shutter so that I save the flight shots (at a set rate of maybe 20-30 fps) without filling the cards with an unknown number of shots of the bird perched while I’m waiting for it to fly to the feeder or water. 7) Finally, the manual for the R3 is horrible. The Instruction Manual provided with the camera is totally worthless – it is basically a how to turn on the camera for dummies and not much more. The 1,074-page Advanced User’s Guide (that you have to download at Canon’s website) doesn’t even have an index to make it easier to locate a topic. It would be nice to have a more compact version of the Advanced User’s Guide (that includes an index) included with the camera. Hopefully if Canon makes an R1 mirrorless it will include most of these suggestions.

Take your photos to the next level with this full frame beauty.

After having a mix of APS-C sensor bodies and full frames, it was time to take the leap. The R3 doesn't disappoint. Bigger batteries, bigger sensor (than an APS-C), bigger photos. If you want to elevate your photography and have great low light photos, the R3 is the camera for you. Go from being ordinary to extra-ordinary!

I love the eye tracking to focus capability on this camera. Still on the learning curve with this guy, but so far it looks to be the best Canon has created so far. B&H was fast and efficient as always.

This camera does not have a dedicated timecode input. if you want to sync this camera with other cameras or other audio devices you will have to use a timecode device that embeds timecode on the audio channel such as a Tentacle Sync Sync E Timecode Generator with Bluetooth (Dual Set) (B&H # TETE2 MFR # TE2) Canon has not announced any Anamorphic shooting modes at this time however it is possible for them to add anamorphic shooting modes with future firmware updates.

Does the R3 have any cross type AF points and dual cross type AF points? If so, how many?
Asked by: Samuel L.
Cross-type and Dual Cross-type AF points are a technology of DSLRs that use a separate auto-focus sensor. Because the Canon EOS R3 is a mirrorless camera that relies on its imaging sensor for AF, this likely means that like the rest of Canon's mirrorless line up, all of its 1053 AF points are single-line horizontal-oriented AF points. Canon has not released information contrary to this, but we will update this answer if new information proves this to be false.
