The Canon EF Lens to Blackmagic Pocket Cinema Camera Speed Booster from Metabones adapts Canon EF lenses to Micro four Thirds mount, while using custom optics to increase the angle of view and the maximum aperture of the lens. It is designed specifically for the Blackmagic Pocket Cinema Camera and features built-in electronics which let you set the lens aperture using the controls on the camera body.

The Speed Booster works by shrinking the image circle of your Canon EF lens down to better fit the smaller sensor of the Blackmagic Pocket Cinema Camera. This has the effect of making the angle of view of the lens 0.58x wider or, in other terms, reducing the crop factor of the camera from 3.02x to 1.75x.

When the Speed Booster concentrates the image circle from a lens, the brightness of the image is increased by 1 2/3 stops. This yields a maximum output aperture of f/0.74 when using a Canon EF f/1.2 lens. In addition to lens speed and angle of view, the Speed Booster also increases the lens' MTF, or how faithfully the lens transfers detail from the object to the camera sensor. These increases in MTF are seen in the corners as well as the center of the images.

To reduce strain on the Pocket Camera's MFT mount, the Speed Booster includes a removable Arca-type tripod foot to help support the weight of the adapter and lens. In addition to being compatible with Arca-type quick-release heads, it also has a 1/4"-20 threaded hole for mounting to other tripods, rigs, or quick-release plates. The built-in electronics are powered by the camera body, so no additional power supply is needed. To reduce the drain on your camera's battery, the Speed Booster uses an efficient switched-mode power supply, which continually switches between on and off states, only drawing power when it needs it.

Note: This Speed Booster is NOT compatible with the Panasonic GH4 or other MFT mount cameras. This is for use with Blackmagic Pocket Cinema Camera only. When the Speed Booster is used with other MFT mount cameras, it's rear element may cause damage to the camera.

Supported
  • EF Lenses
  • Image stabilization (IS) lenses
  • Electronic manual focusing (e.g. EF 85mm f/1.2L II and discontinued EF 50mm f/1.0L)
  • EXIF (focal length, aperture, zoom range)
  • Distance and zoom display on BMPCC camcorders (Requires lenses supporting distance information)
  • Contax N mount lenses modified to Canon EF by Conurus
  • Contax 645 NAM-1 adapter modified to Canon EF by Conurus
  • Sigma, Tamron, and Tokina lenses in Canon EF mount

  • Note: Third party zoom lenses may need to be registered with the Speed Booster first in order to detect its maximum aperture, by zooming to the maximum and minimum focal length, then turning off the adapter to store the settings to the non-volatile memory of the Speed Booster.
Not Supported
  • Autofocus
  • EF-S lenses
  • Lens correction such as peripheral shading, CA and distortion
  • Focus confirmation "chip" (e.g. Dandelion)
  • M42 screw mount adapters (Some improperly-made M42 screw mount adapters may short the electronic contacts of the Speed Booster and cause damage to the Speed Booster and/or camera body)
  • Stacking non-Metabones/non-Conurus mount adapters on top

List of Manual Focus Lenses Which Require MODIFICATION to be Used with Speed Booster
Many manual focus lenses have rear protrusions (spikes, levers, other appendages) which can damage the optics and/or housing of Speed Booster. They need to be modified before they can be safely used on Speed Booster via third party adapter rings. Check and make sure there are no rear protrusions from the adapter/lens combination before using on Speed Booster. The following is an incomplete list of lenses known to be incompatible without modification:

Leica R
  • Super-Elmar-R 15mm
  • Elmarit R 28mm f/2.8
  • Elmarit R 35mm f/2.8
  • Summicron R 50mm f/2

Nikon F
  • 20mm f/2.8 AI-S

Olympus OM
  • 18mm f/3.5
  • 21mm f/2
  • 21mm f/3.5
  • 28mm f/2.8
  • 50mm f/1.8

Pentak K
  • Every Pentax K-mount lens has a protruding fin and an aperture lever, and do not fit.

question

can it use for the new Blackmagic Micro camera?
Asked by: chan l.
There have been discussions on the BMD Forums, and no one has confirmed it for the micro cinema camera. The general consensus there is that since the sensor and mount for the pocket & the micro cinema are the same, the adapter should more than likely work. The micro studio & full size studio camera also share the same sensor and there's one person on YouTube who has demonstrated successfully using a micro studio camera with the standard MFT mount Metabones adapter (that works with the MFT Studio camera). He did say that it was a much tighter fit, though.

question

Will this work on the blackmagic studio camera with the sdi control?
Asked by: Gerardo S.
As this is designed specifically for the pocket, I think it would be safer to use the standard m43 version on any other camera. The new m43 one may also allow auto focus. The micro CINEMA camera may share the same sensor, but I would double check with both metabones and BMD before trying it and potentially damaging the sensor.

question

What's the difference between this and the MB_SPEF-BMPCC-BMT T-Speed Booster ?
Asked by: Anonymous
The EF to BMPCC is a T Speed Booster according to the Metabones website. If you're talking about the difference between this and the EF to MFT T Speed Booster XL which also works on the BMPCC than the main differences are the MFT version only makes the lens wider by .64 vs .58 and increases aperture by 1-1/3 vs 1-2/3 for the BMPCC version. The EF to BMCC T Speed Booster will also work with the BMPCC with the same limitations as the MFT one but doesn't have other problems using lenses with wider apertures. Hope that helps. The Metabones website will have most complete information if you need more specifics.

question

Does this work with lenses for APS-C sensors? Not EF-S lenses, but EF-lenses designed for APS size. I've been looking at the Bower/Rokinon/Samyang 16mm Cine Lens, but I can't figure out if it will work with the MBS and the BMPCC or not.
Asked by: Anonymous
Yes. Sigma 18-35 f1.8 is a great match
