Description
The Used Metabones T CINE Smart Adapter Mark II for Canon EF to RF is a professional lens adapter designed to allow Canon EF and EF-S mount lenses to be used on Canon RF-mount cameras while maintaining electronic communication between the lens and camera body. It supports key electronic functions including autofocus, aperture control, EXIF data and image stabilisation, making it a practical solution for adapting existing EF lens collections to Canon’s RF system.
Designed specifically for professional and cine-oriented applications, the T CINE Smart Adapter Mark II features Metabones’ positive-lock EF mount mechanism, helping secure the lens firmly and minimise play during operation. This is particularly useful for video and cinema applications where precise and stable lens positioning is important.
The adapter combines an aluminium alloy body with brass mounting rings, while the internal surface is finished in matte black to help minimise unwanted reflections inside the adapter. A rubber gasket around the RF mount provides additional protection against dust and moisture.
A detachable Arca-type tripod foot is also included, providing additional support when using larger or heavier EF lenses. The foot is compatible with Arca-type tripod systems and also incorporates a 1/4″-20 tripod thread.

Canon EF to RF Electronic Communication
Unlike a simple mechanical mount adapter, the Metabones T CINE Smart Adapter Mark II maintains electronic communication between compatible EF lenses and RF-mount cameras.
This allows supported lenses to retain functions such as autofocus, aperture control, image stabilisation and EXIF data transmission. The adapter draws power from the camera body, so most compatible lenses do not require a separate power source.
This makes the adapter particularly useful for filmmakers and photographers who want to continue using an existing Canon EF lens collection with newer RF-mount camera bodies.
Positive-Lock CINE Mount
The T CINE version incorporates Metabones’ patented positive-lock EF lens mount, designed specifically to provide a robust connection between the lens and adapter.
The positive-lock mechanism helps minimise unwanted play between the lens and camera system, an important consideration when using manual focus, follow-focus systems or other cinema accessories where mechanical stability is important.
Professional Construction
The adapter features an aluminium alloy body with brass mounting rings. Metabones uses brass and chromium-plated mounting surfaces to provide smooth mounting while helping resist wear from repeated lens changes.
The internal barrel features a matte black finish designed to minimise internal reflections and reduce the possibility of unwanted glare affecting the image.
Detachable Tripod Foot
For larger EF lenses, the included detachable Arca-type tripod foot provides an additional mounting point and helps support the lens and adapter combination.
The foot is compatible with Arca-type systems and includes a 1/4″-20 tripod thread, allowing it to be integrated into a range of tripod and support configurations.
