Works Flawlessly With the Official Canon EF–EOS R Mount Adapter
Because Canon EF DSLR lenses use the exact same electronic protocol as RF cameras (just a 24mm longer flange distance), adding a simple hollow EF-EOS R adapter gives 100% native autofocus speed, Eye-AF, and lens stabilization with zero optical glass loss.

Why can DSLR lenses adapt onto mirrorless cameras, while mirrorless lenses cannot fit DSLRs? The secret is Flange Focal Distance—the exact millimeter gap between the metal lens mount ring and the digital image sensor. When a camera has a short flange distance (16mm–20mm on mirrorless bodies), there is physical room to insert an adapter for longer-flange DSLR lenses (44mm–46.5mm).
