The Canon EOS R is a mid-range model and the company’s first full-frame mirrorless camera. It features the new RF mount, which at 54mm is the same width as the EF mount, but the focal flange distance is reduced from 44mm to just 20mm. This should pave the way to some very high-performance lenses. For its first camera in the system, Canon has opted for a familiar 30.3 megapixel CMOS sensor, paired with a DIGIC 8 processor, which enables a native ISO range of 100-40,000 with expansion to 50-102,400, and continuous shooting at up to 8 fps.
The camera’s CMOS sensor achieves an overall DxOMark score of 89 points, which is 29th place among all small- and medium-format cameras in our database. Its key strength is its low-light ISO (Sports) score of 2742 ISO, where it ranks in 27th place overall and in fifth place among the full-frame Canon cameras we’ve tested. Only 0.2 EV (ISO 2742 vs. 3207) separates the EOS R from the best-performing Canon sensor in the EOS-1D X Mark II. The EOS R’s (Portrait) color depth and (Landscape) dynamic range fall some ways behind the best in class, but as with its low-light ISO capabilities, its results are among the best for a Canon sensor.
