The T CINE Speed Booster ULTRA 0.71x Adapter from Metabones allows a Canon EF-mount lens to be mounted onto a camera with a FUJIFILM X-mount. The adapter's optics maximize the connected lens's apparent angle of view by a factor of 0.71x while providing a one-stop increase for the camera over the lens's aperture range.

This adapter supports electronic communication between the lens and camera body, so AF, image stabilization, aperture control, and Exif data transfer are supported. If a lens designed for 35mm film or similarly sized full-frame camera sensor is connected to a camera with a smaller sensor, it would project an image larger than the sensor was made to render. 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 ULTRA 0.71x adapter condenses the light from a lens designed for 35mm film or "full-frame" camera sensors and projects it onto the sensor. This allows the camera's 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 one f/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 optics feature five lens elements in four groups and are designed to provide optical clarity as well as color fidelity. The detachable tripod foot is Arca-type compatible and features 1/4"-20 threads.

NOTE: This adapter does not support EF-S-mount lenses.

Q: 1. Does this work with the Canon C70?

A: The Metabones Canon EF Lens to RF-Mount T CINE Speed Booster Ultra 0.71x Adapter (EOS-R) is compatible with the Canon EOS C70 Cinema Camera (RF Mount) and EF mount lenses listed on the Compatibility Tab. Here is the link: https://bhpho.to/3RElKB4.

Q: 2. How fast is it compare to fringer?

A: The Fringer does not increase speed

Q: 3. Does image stabilization IS work with sigma art 24-105 and 70-200 lens?

A: Yes, the Metabones Canon EF Lens to RF-Mount T CINE Speed Booster Ultra 0.71x Adapter (EOS-R) supports image stabilization from the Sigma Art 24-105 and 70-200 lens.

Q: 4. Does this adapter work for Canon FD lenses?

A: The Metabones Canon EF Lens to FUJIFILM X-Mount Camera Speed Booster ULTRA will not work with Canon FD lenses; it only works with EF lenses.

Q: 5. Does this work with DZO Vespid Primes and Catta Ace lenses? They aren't on the compatibility list.

A: Yes, both DZO Vespid Prime and Catta Ace (FULL FRAME) lenses will adapt to the Metabones Canon EF Lens to Metabones RF-Mount T CINE Speed Booster Ultra 0.71x Adapter (EOS-R). Please note that this adapter does not support APS-C/S35 lenses. . Compatibility chart: https://bit.ly/3VxTmT3 More info from Metabones: https://bit.ly/429uUd2

Q: 6. What's different from the non-cine version?

A: The CINE version has Metabones' patented positive-lock that locks stiffer and prevents any wiggle which comes into play when using follow-focus devices.

Q: 7. Will this work with the v-Raptor S35?

A: It works with the Komodo X, so it is supposed to work with the V-Raptor S35 as well.

Q: 8. "Although the lens will fit physically, automatic diaphragm (AE metering), or other auto functions will not be retained using this speed booster." Does that mean Aperture priority , Shutter priority, and Auto exposure are not supported ? Only full Manual exposure is available ?

A: You will have full auto focus, and auto metering.

Q: 9. Has anyone experienced unusual flaring problems when shooting against the sun, light bulbs etc with this adapter?

A: Lens flares can occur with any lens especially when pointed towards the sun regardless of whether using a Metabones Speed Booster, a regular Canon adapter, or a native RF lens. Lens hoods can help reduce the risk of flares but they cannot prevent them in all situations.

Q: 10. Ignoring the speedboosting optics, how good are the smart adapter features (AF, stabilization, EXIF) compared to Fringer?

A: Metabones is very well-known for making great adapters; their construction quality, level of support (firmware updates, customer support, etc), and features are typically at the highest level amongst the adapter brands.
