Unsupported List

Standard M43 camera. When this Speed Booster® is used with other MFT camera, it may cause damage to the camera.
EF-S lens. EF-S lenses require modification to fit or may remain incompatible even after modification.
Lens correction such as peripheral shading, CA and distortion
Focus confirmation “chip” (e.g. Dandelion)
M42 screw mount adapters _{(see note 5)}
Stacking non-Metabones/non-Conurus mount adapters on top (see note 5 and list of lenses which require modification below.)

In a nutshell, we recommend XL for full-frame lenses and ULTRA for DX/APS-C lenses. For the long story, read our M43 Speed Booster Compatibility Chart.

Description

The BMPCC4K Speed Booster ULTRA 0.71x and XL 0.64x are similar to the standard M43 Speed Booster adapters (MB_SPEF-m43-BT5 and MB_SPEF-m43-BT6) 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.

In addition to optimized optical design, the CINE version is equipped with an extremely robust cine-style positive locking mechanism to ensure that no play occurs during focusing. This is especially important when using EF lenses for cine work because even though they provide a very smooth focus movement.

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.

The BMPCC4K Speed Booster ULTRA 0.71x reduces the crop factor of the BMPCC 4K camera from 2.02x to 1.43x and produces the largest aperture optics currently available, with a maximum output aperture of f/0.9.
