Canon full-frame mirrorless cameras

After reviewing Nikon’s full-frame mirrorless range, I will now take a detailed look at Canon full-frame mirrorless cameras. The EOS R system is built around Canon’s RF mount, which combines a wide lens throat, a short flange distance, and advanced electronic communication between the body and lens. Canon’s RF lenses are one of the system’s main strengths, and I have covered the entire lineup in a separate guide to Canon RF lenses. That page includes both Canon and third-party lenses compatible with the cameras featured here.

Canon entered the full-frame mirrorless market in 2018 with the EOS R, followed by the more affordable EOS RP in early 2019. The EOS RP targeted beginners and enthusiasts, while the EOS R sat higher in the range. At the end of 2019, Canon also introduced the highly specialized EOS Ra for astrophotography.

Canon moved into a more advanced segment in 2020 with the EOS R6 and EOS R5, two models aimed at serious enthusiasts and professionals. The R6 broadly continued the spirit of the EOS 6D line, while the R5 became the mirrorless successor to Canon’s celebrated 5D series. The professional EOS R3 followed in 2021, before Canon updated the R6 line with the EOS R6 Mark II in 2022. In 2024, the range expanded again with the EOS R5 Mark II and flagship EOS R1, followed by the EOS R6 Mark III in 2025.

Canon EF and EF-S DSLR lenses can be used on EOS R cameras with an EF-EOS R adapter. This gives existing Canon users access to a very broad lens catalog, although RF lenses remain the most natural choice if you are building a new full-frame mirrorless system.

Let’s now look at the main technical features of each camera. At the end of the article, I will also help you identify the model that best matches your photography, video, and budget requirements. If you are working with a smaller budget or want a lighter camera, you can also explore Canon’s older APS-C mirrorless cameras.

In June 2022, Canon introduced its first APS-C cameras using the RF mount. These newer models share the same mount as Canon’s full-frame mirrorless cameras and effectively replaced the older EF-M system.

You can also compare Canon’s range with Sony mirrorless cameras in our dedicated guide.

If you are still hesitating about which camera to choose, I invite you to read our guide detailing all the elements to consider when buying a camera.

We have also published a complete guide to the best current Canon RF lenses for full-frame mirrorless cameras.

The Canon EOS R6 Mark III succeeds the R6 Mark II as Canon’s all-round full-frame mirrorless camera for advanced enthusiasts and professionals. It introduces a new 32.5 MP full-frame CMOS sensor, providing a clear increase in resolution while retaining the speed that defines the R6 series. Electronic burst shooting reaches 40 fps with autofocus and exposure tracking, while the deeper buffer can record up to 150 RAW files in a continuous sequence. Pre-continuous shooting also captures up to 20 frames before the shutter button is fully pressed.

Autofocus is based on an enhanced version of Dual Pixel CMOS AF II, with improved subject recognition and tracking across the frame. The camera also includes Register People Priority, which allows selected faces to remain prioritized in crowded scenes. In-body stabilization is rated at up to 8.5 stops, depending on the lens used.

Video is one of the main areas of improvement. The EOS R6 Mark III records approximately 7K RAW internally, including RAW Light at up to 60p, as well as oversampled 4K, 4K 120p, and Full HD 180p. Open Gate RAW recording provides additional flexibility for reframing content into horizontal, vertical, or cinematic formats during editing.

The camera uses one CFexpress Type B card slot and one UHS-II SD card slot. Its weather-resistant magnesium-alloy body measures approximately 138.4 × 98.4 × 88.4 mm and weighs around 699 g with battery and memory card. Overall, the EOS R6 Mark III offers a stronger balance of resolution, speed, autofocus, and video than the R6 Mark II, making it one of the most versatile cameras in Canon’s current full-frame range.

Released in August 2024, the Canon EOS R5 Mark II is a major evolution of the original R5. It combines the DIGIC Accelerator with the DIGIC X processor to improve autofocus, image processing, and overall responsiveness. The camera also uses the newer LP-E6P battery. Electronic burst shooting reaches 30 fps, while the electronic shutter can operate at up to 1/32,000 sec.

The camera retains a 45 MP full-frame sensor, offering high resolution, strong dynamic range, in-body image stabilization, and weather sealing. For video, it records 8K DCI at up to 60 fps, including RAW Light options. Storage is handled by one UHS-II SD slot and one CFexpress Type B slot, a combination suited to both high-resolution stills and demanding video formats.

The EOS R5 Mark II is slightly larger than its predecessor but remains relatively compact, measuring 138.5 × 101.2 × 93.5 mm and weighing 746 g. Its weather-sealed body is designed for demanding field use. The camera includes a 5.76-million-dot OLED viewfinder, a fully articulated 2.1-million-dot rear screen, and in-body stabilization rated at up to 8.5 stops.

Overall, the EOS R5 Mark II combines high resolution, speed, and advanced video capabilities in a relatively manageable body. Its Dual Pixel Intelligent AF and Action Priority mode make it particularly well suited to demanding photographers and hybrid creators.

The Canon EOS R1 represents the flagship of the EOS R system and is designed primarily for professional sports, news, and action photography. It uses a 24.2 MP full-frame sensor, dual CFexpress Type B card slots, in-body stabilization, and a rugged weather-sealed body. Like the EOS R5 Mark II, it combines the DIGIC Accelerator with the DIGIC X processor for extremely fast image processing.

The EOS R1 reaches 40 fps with its electronic shutter while maintaining autofocus and exposure tracking. Its electronic shutter speed extends to 1/64,000 sec, and the LP-E19 battery is designed for long professional shooting sessions.

The 9.44-million-dot OLED electronic viewfinder offers excellent clarity, while the 4.2-million-dot rear touchscreen provides detailed monitoring and control. Together, they make it easier to frame and follow subjects during fast action.

The EOS R1 also records 6K RAW at 60 fps and 4K at up to 120 fps. Its speed, handling, durability, and autofocus performance make it the natural mirrorless successor to Canon’s EOS-1 DSLR series, aimed primarily at working professionals.

Introduced in April 2023, the Canon EOS R8 is a compact and affordable full-frame mirrorless camera. At 461 g including battery and memory card, it is one of the lightest models in Canon’s full-frame range and sits below the EOS R6 Mark II.

In terms of features, it shares many with the Canon R6 Mk II, including its 24.2 MP sensor, a 3.0″ screen, a 1.62 megapixels screen resolution, and the same autofocus subject detection and tracking algorithms. When it comes to video capabilities, it surpasses the previous RP/R models, offering impressive features like 4K UHD recording at 60p without cropping or, for more advanced users, the option to use Canon’s Log 3 mode. Additionally, it provides the flexibility to shoot full HD slow-motion videos at 180fps. One notable difference is that the Canon R8 lacks 5-axis image stabilization (same as in the Canon R and RP cameras). In terms of ISO, the Canon R6 Mark II maintains the same range, from ISO 100 to 102400.

In terms of handling, the camera is more compact, lacks a joystick, but remains resistant to dust and moisture. The viewfinder has a slightly lower resolution than the R6 Mark II (2.69 megapixels) and lower magnification (0.7x compared to 0.76x on the R6 Mark II). This camera, at its price, doesn’t feature a stacked sensor. Regarding autofocus, it’s identical to the Canon R6 Mark II, offering advanced subject detection modes and Deep Learning technology. In terms of burst, it can achieve 40 fps with the electronic shutter, but only 6 fps with the mechanical shutter, which is half the speed of the R6 Mark II. It’s important to note that Canon has excluded a 100% mechanical shutter option; instead, it offers the 1st shutter curtain mode or the 100% electronic mode. Although the mechanical shutter is only utilized in the 2nd curtain in the 1st mode, it produces a distinct click. The buffer capacity remains limited, allowing only 56 RAWs at 40 fps or 100 compressed RAWs.

Regarding battery life, we fall a bit short of the mark. There’s only one SD card slot (compatible with UHS I and II) and the ‘older’ LP-E17 battery from the EOS M50 II, which significantly limits battery longevity compared to the traditional LP-E6NH found in other Canon full-frame cameras. Canon claims you’ll get about 220 shots using the viewfinder and 370 with the LCD screen. As for connectivity, the camera supports WiFi at 2.4GHz and Bluetooth 4.2.

In short, the EOS R8 delivers much of the EOS R6 Mark II’s image quality and autofocus performance in a smaller, lighter, and non-stabilized body. It is a strong option for enthusiasts moving from an APS-C camera or older DSLR, as well as professionals looking for a compact backup body.

In November 2022, Canon updated the successful EOS R6 with the EOS R6 Mark II. The original R6 had already represented a major step forward from the EOS R and EOS RP, so this second generation focuses more on refinement than reinvention.

The first difference is the sensor, which is now at 24MP resolution, matching the resolution of most competing cameras such as the Nikon Z6 II, the Panasonic S5 II and the A7 III. Nevertheless, it does not benefit from the latest technologies such as backlighting that can be found in the competition or memory stacking found on the most high-end cameras. However, this sensor allows the R6 Mark II to offer a 6K60p video recording without crop although you have to use an external recorder. The sensitivity of the sensor has not changed compared to the R6, despite the additional pixels, since it offers a native range of 100 to 102400 ISO.

Image stabilization remains as good and the mechanical burst rate is still 12 fps. However, in electronic shutter, the burst rate is increased from 20 to 40fps. But without a stacked sensor, this one remains easily subject to problems caused by the sensor’s reading speed such as distortions when following moving subjects sideways, banding in artificial lighting conditions and rolling shutter in video. The AF also remains effective and receives new subject detection, mainly trains and planes. The rear screen and EVF are the same as those of the R6, which were already what you would expect from a camera at this price.

Regarding battery life and connectivity, the Wi-Fi gains the 5GHz band for increased speed and the camera can shoot 50% more photos with the LCD and 15-20% more with the EVF. A good improvement on this point, hybrid cameras being quite criticized on the battery life, but it is still below what Sony is able to offer. Memory cards used are still a dual-slot from SD to UHS-II, rather limited for 6K (hence the interest to use an external recorder via HDMI port).

Overall, the EOS R6 Mark II is a worthwhile update rather than a complete redesign. It improves speed, autofocus, battery life, and video capabilities while retaining the strengths of the original R6.

Canon introduced the EOS R5 C as a Cinema-focused version of the R5, partly in response to concerns about overheating during long recording sessions. The body is thicker and incorporates an active cooling fan. Its stills capabilities remain close to those of the R5, although in-body image stabilization is removed, while the video side offers a much broader range of professional formats, codecs, and recording options.

Video autofocus is less capable than the stills system, and battery life is limited during demanding recording modes. The active cooling system removes recording-time restrictions, but power consumption remains a practical limitation.

The EOS R5 C is one of the most complete hybrid cinema cameras in its class, particularly because of its 8K capabilities, but it is also expensive. Unless you need its advanced video tools, more affordable and practical alternatives are available.

Three years after the first EOS R, Canon introduced the EOS R3, a high-end mirrorless camera designed for sports, wildlife, and photojournalism. It combines ideas from the professional EOS-1D X Mark III with technology from the EOS R5 and R6, all housed in a rugged, weather-sealed body.

It’s a full-frame 24MP camera built around the RF lens mount. This choice allows Canon to compromise between resolution, acquisition speed and file weight, all while maintaining very good performance in high ISO. The sensitivity range extends from ISO 100 to 102,400, expandable to ISO 204,800. There is a sensor stabilized on 5 axes. Its new CMOS sensor allows a maximum shooting speed of 30 fps with AF and AE tracking. The camera is based on a total of 4779 AF points – it is quite a lot, but still less than the EOS R5 (5940 points) and the EOS R6 (6072).

The biggest new feature of the EOS R3 is the Eye Control, an eye-controllable autofocus. All you have to do is look at the subject in the electronic viewfinder, press the AF-On button (or press the shutter release halfway), and the camera will focus and track the subject. Compared to the EOS R5/R6, it also gains a new car and motorcycle detection and tracking mode. Not only that, the AF is also able to detect the rider’s head for an even better focus.

Regarding video, no 8K, but this EOS R3 offers 6K at 60 fps in RAW.

In terms of connectivity, the EOS R3 is quite complete: USB Type C 3.2 port, micro-HDMI port, and 2 jack 3.5 mm (microphone and headphones). It also includes an RJ45 port, intended for photojournalists. For storage, the camera has a slot for SDXC cards (UHS-II compatible) and another one for CF Express cards. The EOS R3 is compatible with 2.4 and 5 GHz Wi-Fi and Bluetooth 5.0.

The EOS R3 was Canon’s most advanced mirrorless camera at launch and remains a highly capable professional body.

At the end of 2019, Canon introduced a version of the EOS R optimized for astrophotography. It has exactly the same technical characteristics as the EOS R, but with two notable differences: a factory-modified full-frame IR filter/sensor (improved sensitivity) and a 30x magnification, instead of the 10x magnification, which places it in the very closed circle of astrophotography cameras.

The difficulty in astrophotography is the lack of light, but also the fact of matching the spectral sensitivity of the cameras with the radiation of celestial objects. It is precisely in this area of the near infrared that nebulae emit. A spectral range in which conventional cameras are not very sensitive, thus requiring an adapted system.

The EOS Ra is unique within this context, as the infrared (IR) filter layer on the sensor of the regular EOS R has been removed, which highlights the red tones that are often difficult to capture with ordinary cameras. Coupled with a reasonably large pixel size of 5.36 microns, this camera promises to capture a lot of light and to produce low noise at higher ISO sensitivities, on account of the sensor size combined with the 30MP sensor’s megapixel.

The EOS R6 and EOS R5 represented a major step forward from Canon’s first RF-mount cameras. They became the natural mirrorless successors to the popular EOS 6D and EOS 5D DSLR lines.

The most obvious difference between the two cameras is resolution. The R5 is based on a new 45-megapixel sensor, which means it offers more than enough resolution for any task. As for the R6, the 20MP is not the most defined on the market, but it is sufficient in most cases and allows for lighter files. The Canon EOS R6 can reach a sensitivity of ISO 102,400 (expandable to ISO 204,800), where the EOS R5 caps at ISO 51,200.

These two bodies also have common technical features, such as the 5-axis stabilization of the sensor. There is also a burst at 12 fps (with mechanical shutter) or 20 fps (with electronic shutter), with real-time subject tracking. And both have 1053 AF points.

Canon R5

One of the major innovations was the introduction of in-body image stabilization. Its arrival was long awaited, especially since the current cameras have increasingly impressive potential in the field of videos. This area is the other main difference between the two cameras: the R5 has the ability to shoot in 8K at 30p and 4K at 120p across the entire width of the sensor, while the R6 captures in 4K at 60p with a slight crop. Both cameras are equipped with headphone and microphone jacks.

As to battery life, the R5 is rated at 320 shots through the viewfinder and 490 on the LCD. The R6 shows slightly better results: 380 photos using the viewfinder in standard mode, and 510 via the LCD screen. Both cameras can be charged if you have a USB-C charger or power bank. They both have two memory card slots, with a difference for the R5 which has a specific slot for CF express.

The Canon EOS R was the first full-frame mirrorless camera to use the RF mount. It is built around the same 30-megapixel Dual Pixel CMOS sensor as the 2016 EOS 5D Mark IV but designed for the new RF lens series. Among the main features: an ISO sensitivity that extends from 100 to 40,000iso (102,400 in extended), 5655 focusing points, bursts in raw up to 8fps, and 4K video at 25fps and Full HD at 60fps. Regarding connections, we find a USB-C input, an HDMI Mini Type C output, a mini-jack microphone input, a headphone jack and a remote control jack. However, there is only one memory card slot in SDXC format, UHS-II compatible, which is a format a little more popular than the XQD of Nikon Z6/Z7.

The 30MP sensor offers good dynamic range and low-light performance, coupled with the latest Digic 8 processor. Overall, autofocus performance is said to be impressive, even at the highest burst speeds. The single AF is fast, accurate and currently leads the market in low-light performance. The camera uses the C-RAW compressed format, which is in my opinion very useful (allowing to have raw files half as heavy!).

The 8 fps burst rate is modest, and tracking moving subjects during continuous shooting can be difficult. This makes the EOS R less suitable for sports and fast action.

When it comes to video, we may also be a little disappointed… Although the EOS R is capable of capturing 4K video with excellent color rendering, it carries an unfortunate 1.83x crop, making it difficult to shoot wide-angle footage. The lack of body stabilization further limits the camera’s utility as a video camera.

The EOS R does not have the most impressive specification sheet, but it remains an important camera as the first model in Canon’s RF system. It offers good image quality, reliable autofocus, and pleasant handling, although its limitations in burst shooting, stabilization, and video make it better suited to enthusiasts than professionals.

The Canon EOS RP is one of the smallest and lightest full-frame cameras in Canon’s range. Its specifications are modest, but it still offers several appealing features: a 26.2-megapixel CMOS sensor, a Dual Pixel autofocus, an ISO sensitivity from 100 to 40,000 iso (extendable to 102,000 iso like the EOS R) thanks to the DIGIC 8 processor, a large touch screen mounted on a spherical head… Relying on 4,779 AF points, the autofocus of the EOS RP proves to be precise and fast. The EOS RP is also able to detect the subject’s eyes and to track this last one, what will bring happiness to all portraitists.

However, the EOS RP is only able to capture 5 frames/second in single AF mode. This is far from some competing cameras, but the EOS R performance is also somewhat limited with these 8 fps. The two Canon mirrorless full-frame cameras (RP and R) are therefore not suitable for uses requiring a very high burst.

About video, the RP is comparable to its big brother, the R. Despite a 4K capture, quality is disappointing, with significant cropping and an autofocus considered quite poor.

The EOS RP offers a useful selection of connections: two 3.5mm jacks (one for an external microphone, the other for headphones), a mini-HDMI jack and a USB type C port. The camera has a single slot for SDXC format memory card and UHS-II compatible.

The EOS RP is a compact and approachable camera with good JPEG quality and responsive operation, from startup to autofocus and shooting. Only its low burst rate and mediocre video quality prevent it from reaching the level of the best full-frame mirrorless… but which are also sold (much) more expensive.

If you want to own a modified full-frame mirrorless camera and prefer to have your warranty intact, this is the one you’re looking for.

The table below summarizes the main specifications of Canon’s full-frame mirrorless cameras. The highly specialized EOS R5 C is not included.

I will begin with the highly specialized EOS Ra. With its 30.3MP 24×36 sensor capable of delivering beautiful high-sensitivity image quality, this makes it significantly more interesting than the APS-C sensor models Canon has offered so far. This model is a sweet luxury for people wanting to explore the universe even further.

For the rest of the range, the right choice depends on your needs and budget.

Although its specifications are not extraordinary, the “small” EOS RP camera turns out to be particularly interesting to study. It is indeed the least expensive of all the full-frame cameras recently released. The main target is therefore photographers who have already used an expert compact, a mirrorless or a DSLR, but who want to switch to a full-frame mirrorless without breaking the bank. Thanks to the quality of the images generated by its full-frame sensor, its overall reactivity and the efficiency of its Dual Pixel autofocus, the  Canon EOS RP is a complete and pleasant camera to use on a day-to-day basis. Its compactness and light weight are considerable assets (200g less than its big brother, the EOS R).

The Canon EOS R sits in the enthusiast segment and is best suited to photographers who value image quality and handling over speed.

With the EOS R, you get, in essence, the image and video quality of the 5D Mark IV but at a price close to that of the 6D Mark II. With a 30MP sensor, fantastic color reproduction, and built-in sensor autofocus, the EOS R can produce beautiful photos with precise focus. It also has remarkable low-light qualities. Unfortunately, while it is capable of delivering excellent image quality, there are mixed review about handling and ergonomics, and the EOS R’s video capabilities are considerably inferior to its rivals. Coupled with the excellent new RF lenses, this camera will be ideal for general and social photography, casual videographers and those looking for a full-frame mirrorless backup camera.

As far as the EOS R6 and R5 are concerned, we are moving into a higher range in my opinion!

The EOS R5 offers a broad range of advanced features aimed at demanding enthusiasts and professionals. Concretely, if you need to shoot 8K video internally – in both RAW and MP4 – and/or take very high-resolution pictures, the Canon EOS R5 and its 45MP sensor was made for you.

If 8K video and very high resolution are not essential, the Canon EOS R6 offers a more balanced and affordable set of features. The Canon EOS R6 appears to be a very well-balanced camera, the 20MP being sufficient for a wide range of photography, and it should be a perfect fit for both educated amateurs and professional photographers. The Canon EOS R6 Mark II remains a strong option, particularly for photographers who do not need the higher resolution and more advanced video tools of the newer EOS R6 Mark III. The EOS R6 Mark III is now the most complete all-rounder in the series, with a 32.5 MP sensor, 40 fps burst shooting, improved autofocus, 7K RAW video, and stronger stabilization.

The Canon EOS R3 is a high-end professional mirrorless camera designed for photographers who need exceptional speed, autofocus performance, and a more robust body. The EOS R3 is a real demonstration of Canon’s technologies: ultra-fast sensor, ultra-fast AF boosted with algorithms, 6K video… and, of course, the “famous” eye-controllable AF. Canon went all out to seduce the professional owners of an EOS 5D Mark IV or an EOS-1D X Mark III… It remains one of Canon’s most capable professional cameras.

The Canon EOS R8 is the most affordable modern full-frame option in the lineup. It provides the same fantastic features as the Canon R6 Mark II but comes in a smaller, lighter, more compact, less customizable, and non-stabilized version. If you’re considering a full-frame Canon camera and have a limited budget, the Canon R8 might be exactly what you need!

I hope this guide to Canon full-frame mirrorless cameras has helped clarify the range and identify the models that best suit your needs.

I will continue to update this article as Canon introduces new cameras.

As mentioned in the introduction, if you are still hesitating in your choice, don’t hesitate to go and check out the article on full-frame Nikon mirrorless cameras. You might find what you are looking for.
