Metabones T Speed Booster XL 0.64x Adapter for Canon EF Lens to BMPCC4K Camera
Brand: Metabones

The BMPCC4K Speed Booster ULTRA XL 0.64x is similar to the standard M43 Speed Booster adapter but the optics have been re-designed to optimize for the filter stack thickness of 2.4mm found in Blackmagic cameras rather than the 4mm of a standard Micro Four Thirds. Metabones Canon EF to BMPCC4K Speed Booster adapters are designed exclusively for Blackmagic Design Pocket Cinema Camera 4K (BMPCC4K). They cannot be attached to any other M43 cameras such as JVC, Olympus or Panasonic cameras.
