30MP full-frame sensor

Arguably the most important single component of any digital camera, and even more important in a mirrorless ILC, is the sensor. The Canon EOS R uses a 30MP full-frame CMOS chip with a low-pass filter which produces images with the exact same output dimensions as - and may in fact be a close relative of - the sensor used in the 5D Mark IV. The sensor is paired with an Digic 8 processor.

The EOS R's standard ISO sensitivity range of 100-40,000 is very similar to the 5D IV's

Assuming we're right about the sensor being closely related to the one in the EOS 5D IV (pending lab testing), it's not a bad thing. The 5D IV's sensor isn't up there with the best full-frame sensors on the market when it comes to either resolution or dynamic range, but it's better than the 26MP sensor in the 6D II and it's arguably the best all-round sensor in Canon's inventory (the 5DS/R offer higher resolution but lower dynamic range and the EOS-1D X Mark II trades resolution for speed and sensitivity). The EOS R's standard ISO sensitivity range of 100-40,000 is very similar to the 5D IV's, too, the two cameras offer the same absolute maximum ISO sensitivity of ISO 102,400.

The EOS R offers Dual Pixel RAW, plus Canon's 14-bit CRW Raw format as well as the relatively new C-Raw, which provides full resolution but much smaller file sizes.
