Newer Versions Available. Please be aware that we rent two comparably priced updates to this adapter: the Metabones Canon EF Lens to Sony E Mount T Smart Adapter V and the Metabones Canon EF Lens to Sony E Mount T CINE Smart Adapter.

Full-Frame Support. The Metabones Canon EF-S Lens to Sony E Mount T Smart Adapter IV allows you to mount Canon EF-mount lenses to Sony E-mount cameras and camcorders. It supports all full-frame Sony bodies, including but not limited to the a7R III, a7 III, and a9.

New to the T Smart Adapter Mark IV. These are all starting to feel redundant. This version adds support for native Canon EF-S lenses, a larger opening improving functionality when using a Tilt-Shift lens, and a matte black “flocking coating” to reduce internal reflections. For the most part, it’s the same as the Metabones Canon EF Lens to Sony E Camera Adapter IV.

Electronic Communication. It gives you full aperture control when shooting in A and M exposure modes, or lets the camera control aperture if shooting in P or S exposure modes. Not only do you have aperture control, but it’s also embedded in the EXIF data. The Metabones adapter also supports compatible lenses’ Image Stabilization functions, allowing you to shoot at slower shutter speeds and helping to eliminate camera shake.

Powered by the Camera Body. This adapter is powered by your camera body. It doesn’t require any additional power source.

Green Power-Save Mode. The power-save mode reduces battery consumption by reducing aperture diaphragm and image-stabilization actuation during image preview.

Durable Metal Construction. This adapter’s barrel and mounts are all constructed of metal. It offers a removable Arca-Swiss type plate for added lens support. Since the aperture blades change as you make adjustments, there’s a “wide-open” button which functions as the opposite of a depth-of-field preview button. Finally, the adapter’s interior has a proprietary anti-reflection coating.
