Metabones T Speed ​​Booster Ultra 0.71x Adapter for Canon EF to RF Mount Cameras

After the release of the Metabones 1.26x Expander and Adapter, now the company has announced the T Speed Booster Ultra 0.71x Adapter for Canon EF Mount Lens to Canon RF Mount Camera, which reduces the crop factor when shooting video in Canon EOS R full-frame cameras.

Now videographers or moviemakers are 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. They can use Canon EF full-frame lenses on cameras with Canon RF mount.

New Metabones Speed Booster is not intended for still photography but will work if the camera is configured to APS-C mode. It uses an advanced 5 element in 4 groups optical design by Caldwell Photographic Inc., incorporating ultra-high index tantalum-based optical glass to achieve extraordinary optical performance with improved corner sharpness, distortion and reduced vignetting.

It reduces the focal length by 1.4 times and increases the aperture by one step compared to setting the adapted lens. For example, 50mm F2.0 in combination with an adapter will become 35mm F1.4. It supports DPAF autofocus, video autofocus, plus has IS lens support. The design received protection from moisture and dust. Speed ​​Booster is made of brass and chrome-plated aluminum alloy.

When recording UHD 4K video, a Canon RF-mount camera is only able to capture the center portion of the image projected on its sensor, creating an in-camera “crop factor.” A Canon EOS R Mirrorless Digital Camera Body and a Canon EOS RP Mirrorless Digital Camera Body feature a UHD 4K crop factor of 1.75x and 1.63x respectively.

This T Speed Booster Ultra 0.71x Adapter supports electronic communication between an attached camera and lens. If the lens includes autofocus, image stabilization, as well as camera-controlled aperture functions, this adapter is intended to allow the use of those features. Also, if an attached lens is capable of generating EXIF metadata when used with a directly compatible camera, this adapter is designed to transfer that information, so it can be saved along with image files generated the combined Canon EF-mount lens and Canon EF-M mount camera.

Price and Availability

Metabones T Speed Booster Ultra 0.71x Adapter for Canon EF to Canon RF Mount Camera has been priced at $479 and it is now available to buy via store.
