As usual in such announcements, the company kept key specifications, such as sensor accuracy, until launch, but revealed some details.
The EOS R3 is supposed to be the first Canon camera to feature a BSI-backlit CMOS sensor, which means the sensor and circuits, like the RAM, are built into the sensor to allow for faster read speeds and performance.
Sony provided such a sensor through the A9 camera, and Nikon recently said it uses a BSI superimposed sensor in the upcoming Z9 camera.
In combination with Canon’s Digic X image processor, this helps the EOS R3 deliver shooting speeds of 30fps in electronic shutter mode while enabling autofocus and auto exposure tracking.
Canon also noted that the camera is able to do this with minimal distortion, which is important, because sports and action photographers often avoid placing an electronic shutter for fast-moving subjects due to the distortion caused by the rotation of the shutter.
The EOS R3 also offers Eye Control autofocus, something Canon used in the EOS 5 in the 1990s.
The company said: This setting allows users to select and move the AF point using their eyes via the viewfinder.
By doing this, Canon aims to reduce focus time in fast-moving situations.
There is also a professional EOS-1D Series-inspired chassis that has great grip in both portrait and landscape modes, and promises the same durability, including dust and water resistance, as Canon’s professional grade 1D series.
Canon did not reveal other major details, such as: prices, video shooting modes and sensor resolution.
And given it’s designed for sports and news photography, and given shooting speeds, it might not be a high-resolution camera like the 45-megapixel R5.
Canon also unveiled three new lenses, the RF 400mm f / 2.8L IS USM, the RF 600mm f / 4L IS USM, and the RF 100mm f / 2.8L Macro IS USM.
