Canon EOS R3

Canon EOS R3

The Canon EOS R3 is a flagship DSLR that has been designed for speed, adaptability, and dependability. It combines technology from the company’s mirrorless EOS R system with the ruggedness and performance you’d expect from a flagship DSLR. The EOS R3 is the first 3-Series camera to be released since the film period, and it establishes itself as a fast-shooting, versatile, and modern mirrorless camera. The EOS R3 is built around a new full-frame stacked sensor, improved AF performance, and a streamlined body design.

For example, the R3’s 24.1MP stacked sensor provides extremely rapid readout speeds, which helps to eliminate rolling shutter distortion and benefits applications like as quick continuous photography and video recording. Another important technology in the R3 is the image stabilization system.

This full-frame BSI CMOS sensor also benefits from an updated DIGIC X processor, which helps to increase overall speed for up to 30 fps continuous shooting with an electronic shutter, 6K 60p raw and 4K 120p video recording, intelligent Dual Pixel CMOS II autofocus with Eye Control AF for intuitive focus point selection, and intelligent Dual Pixel CMOS II autofocus with Eye Control AF for intuitive focus point selection.

A built-in vertical grip makes it an ergonomic choice for lengthy shooting sessions and for moving easily between horizontal and vertical shooting configurations. The R3 is also the first EOS R-series camera to include a vertical grip. The rugged body design incorporates a high-resolution 5.76 million-dot OLED EVF as well as a 3.2-inch touchscreen “Vari-angle touchscreen LCD, as well as dual memory card slots, wireless and wired connectivity, and an updated Multi-Function Shoe design for increased accessory compatibility are all features of the new Samsung Galaxy S5.

Sensor with Full-Frame Stacked Processing and DIGIC X Processor

BSI Stacked CMOS Sensor with 24.1MP resolution

An industry first for Canon cameras, the R3’s sensor architecture has a stacked sensor that allows for extremely high read-out rates, which significantly reduces rolling shutter distortion and allows for quicker shooting performance.

With a back-illuminated architecture, its 24.1MP full-frame CMOS chip gathers light more efficiently, resulting in lower noise, more clarity, and smoother color reproduction, especially when operating in low-light circumstances.

DIGIC X Processor is a high-performance processor.

An improved DIGIC X processor supports the new sensor architecture by providing powerful processing and the capacity to conduct many high-speed activities at the same time, such as shooting at 30 frames per second while taking AF and AE readings before each frame.

The processor also contributes to the realization of a large sensitivity range from ISO 100 to 102400, which is extensible to ISO 50 to 204800, allowing the photographer to operate in a wide range of lighting circumstances.

Shutter with an electronic motor

A significant advantage of the stacked sensor architecture is the very useful electronic shutter feature, which is capable of shooting continuously at up to 30 frames per second for up to 150 raw frames while exhibiting nearly no rolling shutter distortion. With manual or shutter-priority modes, the maximum shutter speed is 1/64,000 sec, and flash sync is even feasible with an electronic shutter up to 1/180 sec when using a mechanical shutter.

Because of its inherent silence, this adaptable shutter function may be combined with a selection of audible shutter noises to be played along with each shutter click to make it simpler for subjects to know when a photograph has been taken.

Additionally, a manual shutter is available, and it provides a maximum continuous shooting speed of 12 frames per second, with a buffer of more than 1000 frames, in addition to a maximum flash sync speed of 1/250 sec.

6K Raw and DCI/UHD 4K Video Recording are both available.

Its 24MP full-frame sensor also contributes to the camera’s impressive video performance by enabling high-resolution 6K raw 12-bit internal recording as well as uncropped 4K 120p 10-bit recording with Canon Log 3. It is also possible to employ both the 6K and 5.6K recording regions for oversampled DCI and UHD 4K shooting, which results in increased clarity, less moiré, and lower noise.

The camera also supports HDR-PQ recording, which is useful for both in-camera HDR creation and external recording. The HDMI connector, which provides a clean 4K output at up to 60 frames per second, is also supported. Additionally, the ability to employ Dual Pixel CMOS AF II when shooting at up to 6K raw is available, as is the ability to compress images using All-I, IPB, and IPB Light compression.

It is also possible to record for an unlimited amount of time, and the R3 is equipped with both microphone and headphone ports, as well as a micro-HDMI Type-D connector allowing output to an external recorder.

Autofocus and image stabilization are two features of the camera.

CMOS AF II with Dual Pixels

The new Dual Pixel CMOS AF II technology has 1053 automated AF points that span the full sensor area, allowing for faster, more responsive, and more precise focusing performance than the previous generation. Subject Detection and tracking have also been improved with this upgraded phase-detection focusing system, which is capable of intelligently recognizing and tracking eyes, faces, heads (including helmets), animals, and vehicles.

The tracking system will automatically lock onto these subjects and maintain sharp focus throughout burst captures. Also enhanced is Dual Pixel AF II’s low-luminance limit, which now allows the camera to focus down to an amazing -7.5 EV for precise focusing even in low-light circumstances.

AF with Eye Control

With the R3, Canon is reintroducing Eye Control AF, which was previously available on EOS digital cameras. This classic feature from the film era has been updated and tweaked to operate in conjunction with the intelligent focusing capabilities of the Dual Pixel CMOS AF system on the Nikon D800.

In essence, Eye Control AF allows shooters to use their eyes to initiate where the focus point is by simply looking through the electronic viewfinder, and then the camera will take over by using subject tracking and detection to keep the sighted target in sharp focus.

Sensor-Shift Image Stabilizer is a type of image stabilization.

Unwanted camera shaking is corrected when shooting handheld with an In-Body Image Stabilizer (IBIS). This feature is especially useful when shooting handheld in low-light circumstances and while capturing movies. According to the lens employed, this 5-axis system can compensate for up to 8 stops of camera shake when used in conjunction with optical image stabilization lenses.

Body Design

EVF with 5.76 million dots and Vari-Angle Touchscreen LCD

It is equipped with a stunning 5.76 million-dot OLED electronic viewfinder that allows for crisp, high-resolution viewing at eye level. It is further helped by the stacked sensor architecture in that it provides blackout-free viewing when working with an electronic shutter and enables a 120-fps refresh rate for realistic motion depiction when working with a video camera.

The huge viewing area of the viewfinder also allows for the display of comprehensive shooting information if requested, and the information display rotates with the camera to provide a more natural viewing experience.

In addition to the EVF, a 3.2-inch display is included “A vari-angle LCD is also available, which has the advantage of allowing you to operate at high, low, and front-facing angles. The touchscreen interface, which has a remarkable 4.15 million dots of resolution, adds to the versatility of the position, while the live view monitoring and playback are both vibrant.

Construction of a Professional-Grade Chassis

Following in the footsteps of flagship DSLR designs, the R3 has a strong and ergonomic body design that includes an integrated vertical grip for greater comfort when shooting in either horizontal or vertical positions. The R3 incorporates both the smart controller and multi-controller from prior EOS cameras, resulting in a more intuitive handling experience.

Its back layout is identical to that of the 1D X Mark III and R5 bodies. This bigger body design also allows for the inclusion of the high-capacity LP-E19 battery, which allows for longer shooting sessions. It is constructed to the same weather-sealed criteria as the flagship EOS-1D X Mark III camera.

Memory Card Slots on Both Sides

There are two card memory card slots on the EOS R3: one CFexpress Type B slot and one UHS-II SD slot, allowing for greater file-saving options. For 6K video recording and quick continuous filming, the CFexpress Type B slot should be preferred, while the SD slot can be used as a convenient backup slot or for less time-sensitive shooting.


A wide range of wired and wireless networking options are available, providing for a variety of means of transmitting images, movies, and voice memo data to and from the device. The camera is physically equipped with a 1000BASE-T Ethernet interface and an RJ-45 socket, allowing for a quick and secure hardwired connection.

When sending data wirelessly, 5GHz Wi-Fi and Bluetooth are both supported for data transmission and remote camera control, respectively. When the device is linked to the R3 via USB, users of certain smartphones can also take advantage of their device’s mobile data to share files directly from the camera via 5G networks when the device is attached to the R3.

An integrated GPS module, which is compatible with GLONASS and QZSS, allows for in-camera position tagging, which helps to speed any geotagging and timestamping requirements that may arise.

Shoe with Multiple Functions for the Next Generation

The Multi-Function Shoe is an improvement to the original hot shoe design that includes a row of pins at the front of the design to allow for increased accessory functionality as well as the provision of power to chosen accessory types that have historically relied on separate batteries.

This updated shoe is compatible with a number of 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, which allows it to be used in conjunction with legacy shoe-mounted accessories such as the ST-E10 Speedlite Transmitter.

In order to produce a really outstanding camera for professional sports and wildlife photographers and videographers, Canon has combined the well-known blueprint of the 1D-X series with all of the advantages of mirrorless technology to create the Canon EOS R3.

It has long been regarded as the pinnacle of Canon’s technological prowess, but the EOS-1DX Mark III DSLR has now been supplanted by Canon’s EOS R3 as the company’s go-to camera for almost anything that moves quickly – whether it is people, animals, birds, or vehicles – this camera can intuitively and almost instantly capture it with the bare minimum of fuss.

Not only has the number of recognized subjects been increased, but the way in which you can focus on them has been improved even further with the addition of Eye Control AF, a feature that at first glance appears to be a gimmick but in practice quickly becomes a natural part of how you use the camera in your everyday activities.

Other notable advantages that the EOS R3 has over its DSLR counterpart include incredible hybrid image stabilization that can compensate for camera shake by up to 8 stops, exceptional low-light AF sensitivity that can detect subjects as dark as -7.5EV, and even faster headline-grabbing 30fps burst shooting, which is combined with a completely silent electronic shutter.
