The Canon EOS R3 combines the 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 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. This full-frame BSI CMOS sensor also benefits from 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, and intelligent Dual Pixel CMOS II autofocus with Eye Control AF for intuitive focus point selection. 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. 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. 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.
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. 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 in nighttime conditions. 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. 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.
