The T CINE Speed Booster XL 0.64x Adapter for Canon EF Lens to BMPCC 4K from Metabones allows a full-frame Canon EF-mount lens to be mounted onto a Blackmagic Design Pocket Cinema Camera 4K MFT-mount camera. While doing so, the adapter's optics help to maximize the connected lens's apparent angle of view while providing a 1.33-stop increase for the camera over the lens's aperture range. This CINE-type adapter features a positive-lock mechanism for EF lenses.

If a lens intended for 35mm film or similarly sized full-frame camera sensors is connected to a camera with a Micro Four Thirds-sized sensor, it would project an image larger than the Micro Four Thirds sensor was built to accept. Able to capture only the center portion of the projected image, the effective angle of view of the lens would be narrowed, creating an in-camera "crop factor." The T CINE Speed Booster XL 0.64x adapter condenses the light from a lens designed for 35mm film or "full-frame" camera sensors and projects it onto a Micro Four Thirds sensor. This allows the Blackmagic Pocket Cinema Camera 4K with a Micro Four Thirds sensor to utilize more of the light gathered by a connected lens, which effectively reduces the crop factor while making available to the sensor an additional 1.33-stop of light for each of the lens's f/stop settings.

This adapter is constructed from aluminum for durability while minimizing weight and its mounting rings are made with brass to further prevent wear and tear. The internal lens elements are designed to provide optical clarity as well as color fidelity, and a detachable tripod foot is included and features 1/4"-20 threads as well as compatibility with Arca-Swiss tripod heads.

The T CINE Speed Booster XL 0.64x adapter supports electronic communication between an attached camera and lens. If the lens includes autofocus, image stabilization, and camera-controlled aperture functions, this adapter is intended to allow those features to be used. Also, if an attached lens is capable of generating EXIF metadata when used with a directly compatible camera, the T CINE Speed Booster XL 0.64x adapter is designed to allow that information to be saved along with image files generated with a combination of the lens, a BMPCC 4K camera, and the adapter.

Key Features
  • Allows a full-frame Canon EF-mount lens to be used with a Blackmagic Design Pocket Cinema Camera 4K MFT-mount camera
  • Maximizes apparent angle of view of combined camera and lens
  • Provides a 1.33-stop increase for the camera over the lens's aperture range
  • Integrated jog dial for incremental aperture adjustment and push-button access to lens's widest aperture setting when used with a compatible Panasonic camera
  • 7 lens elements in 4 groups for optical clarity as well as color fidelity
  • Supports electronic communication between camera and lens to enable autofocus, image stabilization, on-camera aperture control, and EXIF metadata generation when possible
  • Internal coating minimizes reflections within the adapter barrel
  • Detachable, Arca-Swiss compatible tripod foot with 1/4"-20 threads matches the BMPCC 4K camera height
  • Aluminum components for weight reduction
  • Brass mounting rings prevent wear and tear
  • Special positive-lock EF mount for secure attachment of lens with push-button release

Is this compatible with the Panasonic gh6?
Asked by: Andrew
While the Metabones T CINE Speed Booster XL 0.64x Adapter for Canon EF Lens to BMPCC 4K Camera (MESPEFM43BTB), would mount onto a GH6 body, the glass is designed specifically for the sensor on the Blackmagic Design Pocket 4K camera, and it may not focus properly in all ranges with a GH6. We would recommend the Metabones Canon EF Lens to Micro Four Thirds Camera T CINE Speed Booster XL 0.64x (Fifth Generation) (MESPEFM43BT6), instead. https://bhpho.to/3ySvGz6
