Lens Mount

Canon EOS 5DS R has Canon EF lens mount and Canon EOS 20Da has Canon EF/EF-S lens mount. Due to Full Frame sensor in Canon EOS 5DS 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. Due to APS-C sensor in Canon EOS 20Da 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.

No Low-Pass Filter on Canon EOS 5DS R

There is no optical low-pass filter (OLPF), also known as an anti-aliasing filter, in front of the sensor on Canon EOS 5DS R. 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 5DS R it means that you need lenses with optical image stabilization for vibration reduction. As for Canon EOS 20Da nothing can be done. On Canon EOS 20Da it means that you need lenses with optical image stabilization for vibration reduction. As for Canon EOS 5DS R nothing can be done.
