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

Metabones MBSPEF-M43-BTB Reviews

I have achieved Bokeh!!!

By Michael
Rated 5 out of 5
Date: 2022-05-24

Love the fact that I can use my old Pentax glass and get pretty close to the same perspective as if I were using a much heavier full frame camera. My fast 55 with super shallow focus really shines with this. And the locking ring means no more loose mounts. It keeps the lens rock steady.

Awesome.

Love my metabones. Does an amazing job with the image while enhancing my camera to new levels. Beware I have used the T Cine version which are undoubly the best with Leica Elemetar Rs and Rokinon Cine lenses and with the ROkinons there is still play unless the adapter is supported.

Excellent metabone cine Ef mount fits right in solid connection shot with my 50mm cine full frame lens the picture is super sharp I highly recommend it

Image quality is top notch. Only issue is a bit of a jarring difference between mounting lens to this and the non-cine version. It's fairly awkward holding a bmpcc 4k and then holding a lens and trying to undo the clamp on this. But that's a personal gripe. Most won't mind. Awesome product

Better locking system for focus pulling

By RP
Rated 5 out of 5
Date: 2020-08-17

So I am giving this five stars compared to the EF Speed Booster regular mount . Of course the other system is faster, but for my use, having the lens firmly attached to the camera with no jitter for pulling focus, is definitely the way to go. (For this to work most effectively you need to have the adapter bolted to the camera / cage). In the end, it really depends what your shooting style is, but for me, this is the way to go. An so far, it is the only Metabones Speedbooster (I have own four) that I did not need to do any infinity adjustment for (of course ymmv).

Pricey but perfect (almost)

As other reviewers have pointed out, the cine lock mechanism works perfectly fine with one minor flaw. With weather-sealed lens (like EF 70-200mm) it kinda locks but not all the way (but it works fine even with IS). This is due to the lenses having rubber gasket on the mount portion. Other than that, it’s perfect. Infinity focus works nice, with my adapted Leica elmarit-R 28mm (actually tiny tiny bit past infinity but nothing major). Autofocus on bmpcc 4k works nice, too. Though you get better & faster results with the lever on the speedbooster itself than using tap-to-focus or focus button on pocket 4k. This product is HEAVY. Better get yourself a cage (or bottom plate) & lock, as there’s a bit of play going on between MFT mount / speedbooster side. Once it’s locked, no play whatsoever. Overall, extremely well built, worth the money, and sharper than I expected.

So Worth It!

I owned the Viltrox adapters before buying the Metabones Speedbooster. What a difference! This plus the Sigma MC-11 adapter is now allowing me to use my Sigma 18-35mm f1.8 and 24-70 f2.8 lenses with my BMPCC 4ks, BMPCC 6k PRO and the occasional Sony A7siii I rent for my client projects. The quality different is astounding.

Best adapter in the market!

I've had a lot of trouble with AF on my lenses when connecting an EF lens to the BMPCC 4K. Until this adapter! Locks solidly to the MFT mount on the camera and to the EF lenses with no slop at all. Communication between lens and camera is flawless as well. I highly recommend this adapter to everyone!

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
