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.
