Metabones Canon EF Lens to Sony E Speed Booster Adapter

Available Today


This is the 1st generation version of the Speed Booster adapter. For improved optical performance, we’d recommend either the Metabones Canon EF to Sony E Speed Booster Ultra Adapter or Metabones Canon EF to Sony E Speed Booster T Ultra Adapter.

The Metabones Canon EF to Sony E Speed Booster allows you to mount any Canon EF-mount lens to compatible Sony NEX E-mount cameras and camcorders. While electronic communication between the Sony camera and Canon lens is provided, like the other Metabones EF/NEX Adapter, what separates this adapter from all the others is that the adapter effectively increases your lens’ maximum aperture by 1 stop and widens your focal length by .71×. In other words, a Canon 50mm f/1.2 L would become a 35.5mm f/0.9 lens. With optics designed by Caldwell Photographic (the company behind the Coastal Optics 60mm Macro MTF reportedly improves with the Speed Booster.

Like other Metabones EF/NEX Adapters, it allows full control of aperture 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 imbedded in the EXIF data. The Metabones adapter also supports the Image Stabilization function of compatible lenses, allowing you to shoot at slower shutter speeds and help eliminate camera shake. The adapter itself is powered by the camera, so no additional power source is needed. It has a metal barrel construction, with both mounts being metal as well. Since the aperture blades change as you make adjustments, there is a “wide open button” which functions as the opposite of a depth-of-field preview button.

Autofocus is supported with the adapter, but with severe limitations (such as NO CONTINUOUS AUTOFOCUS). At this time, AF is not reliable with Sony NEX Camcorders, though works (slowly) with the Sony NEX photo cameras with newer Canon brand (no third-party) lenses. Sony NEX cameras cannot display aperture values beyond f/1.0. If a f/1.2 Canon EF lens is used with the Speed Booster, the resulting aperture is f/0.9 but the camera body displays f/1.0. Please familiarize yourself with the full list of limitations and the supported lens list found here.


We cannot recommend this product for professional work. We reached this decision after repeated failures in the field, experienced both first-hand by LR-folks and second-hand via rental clients. Though it might work much of the time, it is 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. If you have any questions, please contact us. support@lensrentals.com | 901-754-9100
