Focusing on the camera itself, the EOS R features a high-resolution 30.3MP full-frame CMOS sensor along with a DIGIC 8 image processor. The combination of these technologies offers a wide sensitivity range up to a native ISO 40000, fast continuous shooting to 8 fps, and UHD 4K30 video recording. In addition to imaging, the sensor also facilitates an advanced Dual Pixel CMOS AF system, which uses 5655 selectable points for quickly and accurately acquiring focus. This focusing system is also sensitive down to EV -6 for working in impressively dark conditions. The AF system is also perfectly matched to the UHD 4K video recording capabilities, which are also rounded out by Movie Digital IS to minimize camera shake, built-in Canon Log gamma for a greater dynamic range, and 4K 10-bit 4:2:2 output over HDMI for even greater color control.
Beyond the performance attributes, this camera has been designed from the ground up and features a high-resolution 3.69m-dot OLED electronic viewfinder for clear and bright eye-level viewing. Conversely, a rear 3.15″ 2.1m-dot LCD touchscreen is also featured, and has a swivel design to suit working from high and low angles.
Beginning with a new lens mount, the EOS R is the first camera to support Canon’s line of RF-mount lenses. This mount is characterized by its wide 54mm diameter and short 20mm flange-back distance, which promotes the ability to design lenses that are both faster and smaller than their SLR equivalents. The mount also incorporates a 12-pin electronic contact system for more sophisticated autofocus and image stabilization capabilities. This mount design also lends full compatibility to existing EF and EF-S-mount lenses via an optional EF-EOS R Mount Adapter.
