The T 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.

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 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 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 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
  • Locking mechanism for secure attachment of lens with push-button release

Back Focus Issues

By Alessandro
Rated 3 out of 5
Date: 2021-11-03

Great unit but the glass element inside needs to be rotated to adjust for flange distance to lens. I was having problems focusing at infinity but resolved the problem.

Excellent piece of tech

This is my second metabones adapter and I am loving it! Makes my pocketcam a super35 with an extra stop of light. Easy to use, well made and fair price.

Metabones is top notch in quality and the science behind it is rock solid. My 2.8 on a mft sensor turns into a 1.8 with more of a super35 look. Love it!

Full-Frame BMPCC 4K

By Liam
Rated 5 out of 5

The XL does what should be impossible. It practically turns the BMPCC 4K — the *4K*, not even the 6K — into a full-frame cinema camera. The 4K's M4/3 sensor has a natural crop of 1.9x over a standard full-frame sensor. This speed booster takes that 1.9x crop down to a 1.2x crop, and you can use full-frame Canon EF lenses on it almost as you would on a regular full-frame Canon camera.  Putting this speed booster on a 4K gets you much closer to full-frame than even a 6K would, which with its super 35mm sensor has a natural crop factor of ~1.5x (1.558x). And even if you put the Lucadapter on a 6K, that gets the 6K down to a crop factor of about 1.1x. The Lucadapter and this Metabones cost about the same amount, and you get to keep using the more affordable 4K rather than the 6K with its better (albeit still terrible) battery life and less audible fan noise, and you get to a crop factor of a mere 1.2x, vs the 1.1x you could get with the 6K. I mean, pretty incredible. It shouldn't really be possible to get near-full-frame results with a M4/3 sensor, but $650 and some Canon lenses later, and here we are.

A Must have.... no, literally.

If you plan on using Canon glass... g'head and CLICK Add To Cart now. After you do THAT.... then read the reviews people have. If you're still reading this, you're likely just wanting to see what people say about this expensive Must Have as you continue gathering intell before buying. Well, lemme help you out. This is the adapter you want to have in your arsenal (unless you do some simple math while considering the Pocket 6K. (more on that at the end) : - For Full Frame Canon lenses, like the L-Series glass, THIS 0.64x will provide you with the best coverage of your sensor to take advantage of the full frame glass (a better choice FOR ME over its sister, the 0.7x) Mathematically, we see more because the adapter is working to compensate for the smaller sensor. To our eye though... and most people... dude... you can't tell. (but as an artist, you know what you want to visually communicate to your audience, and the closer we can get to FULL FRAME art, the richer the experience is for the viewer. This filter is that scientific and technical nuance that makes a subliminal and subconscious difference in the works as a content creator. IF you operate at the level.) - Metadata detailed information about the lens is communicated to the recorded video files of the Pocket 4K. Cool fun fact. - With this adapter, the Pocket 4K will be able to communicate with the lens so that you can utilize the WONDERFUL auto focus feature of the camera by touching the LCD screen in the area you want to lock-in the focus point. (Hands off the lens barrel kids) Don't use the feature while rolling though.... it takes some breathing before it locks in. THAT is strictly a camera thing... don't lemme deviate. Where was I.... - Spend the money. Crazy that an adapter is HALF THE PRICE of the darn camera itself !! Hahaha Make ya wanna find some B4 mounted glass that's native to the camera mount, huh ??? NO!!!! Stick with CANON FULL FRAME GLASS. All. Day. Long. (That Pocket 6K is looking really really good right now huh??!! Hahaha. NO NEED FOR AN ADAPTER !!!! I'm just sayin') Have a blast shooting no matter what gear you rock with!! Let's GO!! - Brian Kyle Atkins

I use this to adapt Canon lenses to my Black Magic 4K Pocket Cinema Camera. It does a good job with the canon glass, but it seems to have problems with focus with my non canon lenses.

The Metabones T Speed Booster XL 0.64x has a wider angle of view and is recommended only for full frame lenses (a crop factor of 1.28). The Metabones T Speed Booster ULTRA 0.71x Adapter does not have as wide an angle of view but will work with full frame and crop sensor lenses (a crop factor of 1.5).

If I put this on my BMPCC4K what will be the crop on a full frame lens?
Asked by: Levi
This will compensate for the crop factor my increasing the angle of view on a lens by 0.64x. As an example if you take a 24mm lens you would do this formula: 24 x 0.64 = 15.36 x 1.9 = 29.18. A 24mm lens will be around a 29mm lens which is around a 1.2x crop.
