A common phenomenon when shooting fast-moving subjects with a rolling shutter is that part of the frame may be blurred or distorted . With the back-illuminated stacked CMOS sensor working in tandem with the DIGIC X image processor , the high readout speed of the EOS R3 keeps the rolling shutter distortion to just 25 % of what the EOS-1D X Mark III produces .
