Metabones Canon EF to RF-mount T Speed Booster ULTRA 0.71x (EOS R)

Metabones Canon EF to RF-mount T Speed Booster ULTRA 0.71x

SKU: MB_SPEF-EFR-BT1

Metabones EF-RF Speed Booster ULTRA 0.71x - to adapt Canon EF mount full-frame lenses to the new Canon RF mount. Filmmakers are now able to mitigate most of the 4k video crop factor of EOS R (1.75x) and EOS RP (1.63x) and reduce it to 1.24x and 1.15x respectively. The field of view is now much closer to still photo mode. This new Speed Booster is not intended for still photography but will work if the camera is configured to APS-C mode.
