Metabones SpeedBooster Canon EF to E-mount T Ultra
The T Speed Booster Ultra 0.71x allows a full-frame Canon EF-mount lens to be mounted onto a Sony E-mount camera.
The adapter's optics help to maximize the connected lens's apparent angle of view while providing a 1-stop increase for the camera over the lens's aperture range.
This 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 those features to be used.
It also allows the generation of EXIF metadata.
