At the heart of the EOS R3 camera's performance will be an EOS camera first, a Canon-developed, full-frame stacked CMOS sensor with a back-illuminated design, providing substantially faster read-out speeds during still-imaging recording. This completely new sensor is designed to produce less "rolling shutter" distortion during Electronic Shutter operation and offers continuous Electronic Shutter still-image shooting at speeds up to 30 fps with full Dual Pixel CMOS AF and auto exposure. Also, the electronic shutter function will even support flash sync when working with Canon Speedlites.

The AF system will leverage technology and performance from the well-received EOS R5 and EOS R6 cameras, using Deep Learning technology to further enhance eye and body detection for even better performance during portrait and action-type shooting. In addition, the EOS R3's subject detection AF will offer new recognizable subjects for its AF system, bolstering its focusing capabilities during challenging shooting conditions.

The Electronic Viewfinder of the EOS R3 will offer photographers the ability to select the initial area for AF tracking by simply looking directly at the viewfinder location where they want to begin AF. With Eye Control AF and Servo AF activated, the camera will focus on and track moving subjects at that location in the frame. When Face Detect + Tracking is active, the camera will continue to follow moving subjects around the entire active AF area.

With the EOS R3, you will be able to shoot in high-quality 4K with Canon Log3 and oversampled 4K, and raw movie internal recording. AF tracking for people, animals and motorsports will be possible while recording video as well.

Able to autofocus in light as low as EV -7 or more, along with up to 8 stops of Coordinated IS control when used with RF lenses featuring Optical Image Stabilization, the EOS R3 will deliver amazing performance even in remarkably dark areas.

The EOS R3 features a solid yet lightweight magnesium alloy body and carries forward the integrated vertical grip similar to the 1D series cameras, emphasizing both horizontal and vertical handling for challenging shooting situations. Weather-resistance and durability will equal Canon's top-of-the-line EOS-1D X Mark III camera, and power will be delivered by the same Canon LP-E19 battery pack, too. And, the EOS R3 will have three primary input dials, giving familiar operation to current Canon EOS users. In terms of memory card support, a dual slot configuration will offer one CFexpress Type B slot and one SD slot.

The camera will also feature a multi controller to help you easily select the AF point, quickly change Menu settings, and more. And, the R3 will also be equipped with a smart controller-similar to that on the EOS-1D X Mark III, which lets you quickly shift AF point locations, or a starting point for Servo AF tracking. A vari-angle LCD will make it easy to compose shots at virtually any angle, and will be touchscreen to enable you to access menus, change settings, and more on the fly. And a new accessory shoe will provide options for data communication and power, supporting new accessories.

To assist with professional or personal photo and video endeavors, the EOS R3 will have Wired LAN and 5GHz Wi-Fi built-in so you have the flexibility of wired or wireless connections and the necessary support for high-speed image transfer.
