The Metabones Canon EF-S Lens to Sony E Mount T Smart Adapter IV is another iteration of the Metabones Smart Adapter for EF to E. Key features include:

  • New inner-housing design with an anti-reflective coating

  • Electronic communication with the camera

  • Powered by the camera body

  • Green power-save mode

Full-Frame Support. The Metabones Canon EF-S Lens to Sony E Mount T Smart Adapter IV supports the full-frame Sony a7 series 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.

Canon EF Lens To Sony E Camera. This adapter allows you to mount Canon EF-mount lenses to Sony E-mount cameras and camcorders. It offers full-frame coverage, making it the go-to Canon adapter for use with the a7, a7R, and a7S.

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.

We cannot recommend Metabones adapters for professional work. We reached this decision after LensProToGo folks and rental clients experienced repeated failures in the field. Though it might work much of the time, it’s our opinion that this product’s performance is too unpredictable to be trusted on high-value projects. Use for casual testing or try-before-you-buy purposes only. USE AT YOUR OWN RISK!
