Metabones SPEF-EFR-BT1 – Canon EF to Canon RF Speed Booster ULTRA 0.71x
It adapts full-frame Canon EF lenses to RF-mount cameras and reduces their crop factor: from 1.60x to 1.14x on EOS R7/R10 and from 1.45x to 1.03x on the EOS C70. RED KOMODO 6K and KOMODO-X are also supported. On full-frame RF bodies (e.g. EOS R5, R3) it works in APS-C mode and video crop modes, not for full-frame stills.
