Did Canon Miss the Memo That Says Mirrorless Lenses Are Meant to Be Smaller?

When Canon introduced their new Mirrorless cameras earlier on this year (The EOS R) one of the stand out features was that the lens mount was so huge. While other manufacturers like Sony have made all things Mirrorless smaller, the late comer to the Mirrorless party seems to have decided that bigger is better. In a recently released interview, Canon engineers seem to be having a sly dig at Sony by saying that lenses with smaller mounts are far less capable than those with larger mounts.
