Lens Mount

Cameras have Canon RF lens mount. Due to APS-C sensor in Canon EOS R100 its crop factor is equal to 1.6x, this means that a 35mm equivalent focal length of the mounted lens will be equal to its actual focal length times 1.6. Due to Full Frame sensor in Canon EOS R its crop factor is equal to 1x, this means that a 35mm equivalent focal length of the mounted lens will be equal to its actual focal length.

No Low-Pass Filter on Canon EOS R100

There is no optical low-pass filter (OLPF), also known as an anti-aliasing filter, in front of the sensor on Canon EOS R100. This results in a slightly sharper image but may also introduce moiré patterns and aliasing artifacts when photographing subjects with fine, repetitive patterns or details.

No Image Stabilization

The cameras do not have image stabilization. On Canon EOS R100 it means that you need lenses with optical image stabilization for vibration reduction. As for Canon EOS R nothing can be done.
