The Canon EOS R is “revolutionary.”
Canon has officially unveiled the new EOS R, the company’s first full-frame mirrorless camera.
The RF mount features a 54mm inner diameter, the same as Canon’s EF mount, but it has a shorter flange focal distance of 20mm that allows lenses to be simpler and optically superior. The RF mount uses 12 electrical contacts for the fastest-ever communication between the camera bodies and lenses. The mount is “an uncompromising balance of optical, mechanical and electronic engineering excellence enabling innovative full-frame lens designs, faster autofocus and high-speed communication between the camera and lens,” says Canon.
Canon is designing a new line of RF lenses specifically for this new mirrorless ecosystem, but the entire lineup of EF, EF-S, TS-E, and MP-E lenses are compatible with the camera if you use the EF-EOS R Mount Adapter. In addition to the standard Mount Adapter, Canon has also created a Drop-In Filter Mount Adapter or Control Ring Mount Adapter to add additional functionality (i.e. filters and a customizable control ring) when adapting lenses.
The Drop-In Filter Mount Adapter is available with a variable neutral density (V-ND) filter or a circular polarising (C-PL) filter. A third clear (CL) filter is also available.
At the core of the EOS R is a 30.3-megapixel full-frame CMOS sensor with an ISO range of 100-40000 (expandable to 50-102400), backed by a DIGIC 8 image processor. There is a low pass filter in front of the sensor that helps combat moiré patterns at the cost of slightly reduced sharpness. The camera has an 8fps continuous shooting speed (for bursts of up to 100 max-quality JPEGs, 47 RAW, or 78 C-RAW), a shutter lag is as short as 50 milliseconds, and a startup time of 0.9 seconds.
The autofocus system of the camera has a maximum of 5,655 AF points using Canon’s Dual Pixel CMOS AF phase-detection system. The AF works at up to f/11 and features a 384-zone (24×16) real-time metering system. It can function well in low light thanks to its working range of EV -6 to 18 (EV -6 AF sensitivity requires f/1.2 lenses). The AF system can achieve focus in as little as 0.05 seconds (when using the new RF 24-105mm f/4L IS lens), which is presently the fastest autofocus speed in the world, Canon says. Other focusing features include Touch and Drag focusing and Focus Peaking.
Silent shooting in single-shot mode will allow photographers to be stealthy while working, and the feature will be available for continuous shooting in the future after an upcoming firmware update.
On the back of the camera is an OLED 3.69-million-dot electronic viewfinder with an approximately 100% coverage and a magnification of 0.71x. Under the EVF is a 3.15-inch, 2.1-million-dot Vari-Angle touchscreen LCD monitor. Above the LCD screen and to the right of the EVF is a new feature Canon has introduced a new Multi-Function Bar which allows users to quickly access customizable settings — things like autofocus, ISO, and white balance. You can both tap and slide your finger across the bar to access settings and adjust them.
In the area of video, the EOS R can shoot in 4K at 30fps and 1080p at 60fps with Canon Log (12 stops of dynamic range), 10bit 4:2:2 HDMI output, and a maximum recording time of 29 minutes and 59 seconds. The side of the camera has mic and headphone jacks.
Other features and specs of the EOS R include sensor self cleaning, dust deletion data, face detection AF, Wi-Fi, Bluetooth, a USB 3.1 terminal, LP-E6N battery compatibility (and up to 560 shots per charge), USB charging, a working temperature range of 32–104°F (0–40°C), a working humidity range of 85% or less, physical dimensions of 5.35×3.87×3.32in (135.8×98.3×84.4mm), and a weight of 1.28 lbs (580g).
