The Canon EF Lens to Blackmagic Pocket Cinema Camera Metabones Speed Booster allows you to pair select Canon EF mount lenses with the Blackmagic Pocket Cinema Camera in Micro Four Thirds mount. It increases the effective field of view and the maximum aperture of the lens you're using. This is handy for achieving wider views with more dramatic depth of field effects on what is otherwise a sometimes uncompromising camera sensor due to its small 16mm size.

The Speed Booster works by shrinking the image circle of your Canon EF lens down to better fit the smaller 16mm sensor. This has the effect of making the field of view of the lens 0.58x wider or, in other terms, reducing the crop factor of the camera from 2.88x to 1.75x. For example, a 30mm lens becomes an effective 52.5mm with this Speed Booster on a Blackmagic Pocket Cinema Camera instead of the 86.4mm effective view you'd have with a straight adapter. This is closer to the APS-C view of around 45/48mm for this particular lens example. Your Micro Four Thirds mount BMPCC will render less like a 16mm sensor and more like the larger APS-C or Super 35 sensor thanks to this Speed Booster, plus you have the benefit of using a wide variety of Canon EF lenses.

By concentrating the image circle from a lens, this Speed Booster also "brightens" the image – maximum lens apertures are increased by approximately 1.66 stops down to the sub-f/1.0 range. Both the camera end and the lens end of this adapter are made of brass that are precision-machined and plated with chromium. The Canon EF Lens to Blackmagic Pocket Cinema Camera Metabones Speed Booster is a great tool for those using the original Micro Four Thirds mount BMPCC and want to also use a large selection of Canon EF mount lenses while getting that added benefit of a "boost" to both field of view and maximum aperture.

Please see the "Notes" section for important information about autofocus and lens compatibility.


  • • This Speed Booster is compatible only with EF mount lenses and not Canon EF-S mount lenses. Non-Canon EF mount lenses in crop frame format, such as the Sigma 18-35mm f/1.8, will mount to this adapter but may experience vignetting. Experiment at your own risk.
  • • This Speed Booster is only compatible with the Blackmagic Pocket Cinema Camera in Micro Four Thirds mount and is not compatible with cameras like the Panasonic GH5 or GH4.
  • • This Speed Booster will not operate correctly when trying to use it on Canon's CN-E collection of cinema lenses for still photography purposes.
  • • When using lenses with apertures faster than f/1.8, the pre-boost apertures will be displayed in the camera. For example, it won't show f/0.7 with a f/1.2 lens attached. It will show f/1.2. The widest aperture where you'll see a boost displayed is f/1.8 (which will show f/1.0). The "boosting" is still occurring, it just doesn't show it on read-out for these ultra-fast lenses.
  • • While technically compatible with any EF mount lens, please take notice if your third-party lens has any mount protrusions, like spikes or levers. These will damage the Speed Booster.
  • • Autofocus is not supported with this Speed Booster.
  • • The following EF mount lenses have been tested by Metabones for use with this Speed Booster. Other EF lenses are certainly compatible but the following have been fully vetted by Metabones:
