๐ Sensor and Image Quality
๐ธ 24.2MP Stacked Sensor Innovation

The Canon EOS R1 features a 24.2MP full-frame stacked CMOS sensor. This sensor is a new design, different from the one used in the EOS R3, boasting faster readout speeds. According to Canon, the R1’s rolling shutter effect is even faster than the mechanical shutter of the 1DX Mark III.
In real-world tests, images captured while panning quickly at 40fps showed almost no distortion of vertical lines. This will be a significant advantage when photographing sports or fast-moving subjects.
๐ฎ AI Upscaling for Enhanced Resolution

Instead of a pixel shift mode, the R1 offers AI-based upscaling. This feature can increase the resolution of JPEG or HEIF files by 4x (2x per axis) to create 96MP images in-camera. The processing time is about 5 seconds.
Comparing upscaled images with the originals reveals intelligently enhanced sharpness and more details in specific areas. The process seems to recognize particular elements of the subject and enhance each differently.
๐ก Evolution of Noise Reduction
The R1 also introduces a new neural network-based noise reduction feature. This option can be selected when processing RAW files, with results saved as new JPEG or HEIF files.
Comparing images shot at ISO 12,800, the version with neural network noise reduction applied was noticeably cleaner with better-defined edges than the original. The effect of this feature is particularly pronounced at high sensitivities.
๐ Burst Performance and Buffer

โก Impressive 40fps Speed
One of the Canon EOS R1’s standout features is its remarkable burst performance. It can achieve continuous shooting speeds of up to 40fps using the electronic shutter, which is industry-leading. Even with the mechanical shutter, it offers a fast 12fps.
Notably, the camera provides a range of frame rate options: 40, 30, 20, 15, 12, 10, 7.5, 5, 3, 2, and 1fps, allowing flexibility for various shooting scenarios.
๐ฐ๏ธ Pre-Capture for Decisive Moments
The R1 offers a pre-capture option when using the electronic shutter. This feature stores up to 20 images in the buffer while the shutter button is half-pressed. At 40fps, it captures 0.5 seconds of action, or 1 second at 20fps.
This feature is invaluable for capturing unpredictable action, such as the moment a soccer ball is kicked or a bird takes flight. It ensures you don’t miss the critical moment while waiting for the perfect time to press the shutter.
๐ก๏ธ Thermal Management Capability

The R1 maintained consistent temperatures even during extended high-speed burst shooting and pre-capture use. This is one advantage of the R1’s large body, which allows for effective separation of internal heat-generating components and better thermal management.
However, some tests observed banding when shooting very bright artificial lights directly. This could be due to the electronic shutter and may be improved in the final product.
๐ฏ Innovative Autofocus System
๐ง AI-Based Subject Recognition

The Canon EOS R1’s autofocus system has evolved further with the help of the new DIGIC X processor. In addition to recognizing people, animals, and vehicles, it can now identify new subjects such as horses, airplanes, and trains.
Person recognition, in particular, has been significantly improved. It can more accurately identify faces and upper bodies, maintaining focus on the original subject even when another person crosses in front. The ability to recognize actual sports movements has also been added.
โฝ Action Priority Mode

The new ‘Action Priority’ mode uses knowledge of three sports - soccer, basketball, and volleyball - to predict ball movement in games and automatically switch AF areas. For example, if it recognizes one player passing to another, it automatically shifts focus to the receiving player.
Currently limited to these three sports that use large round balls, there’s potential for expansion to other sports in the future.
๐ค Face Registration Feature
The R1 allows registration of up to 10 faces with assigned priorities. Impressively, registration is possible with just a single frontal photo. Registered faces are indicated by special icons in live view and continue to be recognized even when the person turns to a profile view.
This feature is not only useful for focusing on specific players in sports events but also practical for wedding or event photography where key individuals can be pre-registered for priority focus.
๐ Cross-Type AF Sensors
The R1 is Canon’s first camera to feature cross-type automatic focus imaging sensors. In the traditional 2x2 Bayer array, the photodiode pair under the second green filter is rotated 90 degrees to implement the cross-type functionality.
This results in improved focus accuracy for vertical details, making the R1’s AF noticeably faster and more responsive than the R5 Mark II.
๐๏ธ Enhanced Viewfinder and Eye Control
๐บ High-Resolution OLED EVF

The Canon EOS R1 features a top-of-the-line electronic viewfinder with a 9.44 million dot OLED panel and 0.9x magnification. This provides a larger, more detailed, and brighter image than the R3.
It also offers a blackout-free shooting option, allowing uninterrupted subject tracking during continuous shooting. However, using this feature may introduce slight latency.
๐ Improved Eye Control Technology
The R1 has further developed the eye control technology first introduced in the R3. This feature tracks the user’s pupil position to select AF points.
Eye control is particularly useful for selecting among subjects already recognized by the AF system. For example, it can quickly choose a desired subject among a sports team, a flock of birds, or multiple people at a wedding.
Accuracy can be improved by repeating the calibration process, and settings for multiple users can be saved, making it useful in shared camera environments.
๐ฅ Video Capabilities

๐๏ธ Various Resolutions and Frame Rates
The Canon EOS R1 boasts impressive video performance. It can shoot up to 8K 30p or 4K 120p, supporting both traditional 16:9 UHD format and wide DCI format.
In 4K Fine mode, it oversamples from 6K data for sharper footage, and 6K DCI can be shot up to 60p in Canon’s CRM RAW format. It also supports ProRes RAW output via HDMI.
๐ Video Pre-Capture
The R1 offers a pre-capture function for video as well. You can choose a 3 or 5-second buffer, ensuring you don’t miss crucial moments.
๐ธ Simultaneous Capture Mode
A new feature allows simultaneous capture of still images during video recording. However, in this mode, video quality is limited to 1080p, and still images are captured at 17 megapixel resolution in 16:9 ratio.
๐ก๏ธ Thermal Management and Extended Recording
The R1 uses graphite sheets and aluminum alloy plates for the sensor and card slots to effectively dissipate heat. According to Canon, continuous recording for at least 2 hours is possible in most formats up to 60p.
Considering that the previous R3 model was only limited by memory or battery capacity, the R1 is expected to show similar stability.
๐ Design and Ergonomics
๐๏ธ Robust Body with Integrated Vertical Grip
The Canon EOS R1 boasts a sturdy and durable body. It’s slightly larger and heavier than the R3 but still smaller and lighter than the 1DX Mark III DSLR.
The integrated vertical grip adds definite robustness and reliability to the camera. Its fully weather-sealed design allows for worry-free use in any shooting environment.
๐ Dual Control Layout

The R1 duplicates key controls for convenient operation in both horizontal and vertical shooting. The joystick, smart controller, AF-ON button, and others are identically positioned on the vertical grip, allowing for quick and intuitive operation in any posture.
๐ก Backlit Buttons
Like the 1DX Mark III, the R1 also features backlit rear buttons. This enhances usability by making buttons easily identifiable in dark environments.
๐ Connectivity and Storage Media

๐ High-Speed Network Support
The R1 supports the latest Wi-Fi 6E, allowing connection to less congested 6GHz networks. The Ethernet port has also been upgraded to support 2.5Gb speed, enabling faster wired connections.
๐ก Built-in GPS
Like the R3, the R1 features a built-in GPS receiver. This allows tagging of images with location data and local time without additional accessories.
๐พ Dual CFexpress Type B Card Slots
The R1 provides two CFexpress Type B card slots. This is the same configuration as the 1DX Mark III, ensuring fast write speeds necessary for high-speed continuous shooting and high-resolution video recording.
๐ Battery Life
The R1 uses the LP-E19 battery pack, providing approximately 1,330 shots when using the screen and about 700 shots when using the viewfinder, according to CIPA standards. This is an improvement over the R3, but in real-world use, many more shots are likely possible.
