Metabones Canon EF Lens to BMPCC Speed Booster

Fits Canon EF Lens to BMPCC MFT Mount - Reduces Crop Factor to 1.75x - Increases Maximum Aperture by 1 2/3 Stop - Built-In Aperture Control Electronics - Aperture is Set Using Camera Buttons - 32-Bit Processor - Efficient Switched-Mode Power Supply - Powered by Camera Body - Removable Arca-Type Tripod Foot


Canon EF to BMPCC Speed Booster adapters designed exclusively for the Blackmagic Pocket Cinema Camera (BMPCC). Note that this new 0.58x Speed Booster will only attach to BMPCC equipped with a Micro-4/3 mount. They cannot be attached to standard Micro 4/3 cameras (cannot be attached to GH4, GH3, GH2 and GH1 body). The new 0.58x Speed Booster reduces the crop factor of the BMPCC from 3.02x to 1.75x and produces the largest aperture optics currently available, with a maximum output aperture of f/0.74.

 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
