Standard M43 camera. When this Speed Booster® is used with other MFT camera, it may cause damage to the camera.
APS-C(DX) lens. Speed Booster XL 0.64x can be used with full-frame lenses only. APS-C lenses are unable to cover full-sensor-width readout.
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.)
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 Boosteradapters 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 XL 0.64x reduces the crop factor of the BMPCC 4K camera from 2.02x to 1.29x and produces the largest aperture optics currently available, with a maximum output aperture of f/0.8.
Table of compatibility and resulting crop factors with different SpeedBooster® :
This Speed Booster is designed to cover a BMPCC4K image circle which is not big enough to cover a full-size 36mm x 24mm sensor.
For use with fast lenses (faster than f/1.4), the pre-boost apertures will be displayed in the camera.
Slow lenses will report boosted apertures to the camera body but fast lenses will report pre-boost apertures. We won't show f/0.8 with a f/1.2 lens attached, but show f/1.2 instead.
a) EF 85/1.2L attached, camera display = f/1.2, physical aperture (lens + Speed Booster combined) = f/0.77. b) EF 35/2 attached, camera display = f/1.3, physical aperture (lens + Speed Booster combined) = f/1.3.
External 5V power via micro USB port may be required (not included).
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.
Many manual focus lenses (e.g. OM 28/2.8, OM 50/1.8, Leica R 15/3.5) have rear protrusions (spikes, levers, other appendages) which would damage the optics and/or housing of Speed BoosterTM They need to be modified before they can be safely used on Speed Booster. Check and make sure there are no rear protrusions from the adapter/lens combination before using on Speed Booster. Scratches and damages caused by rear protrusions on Speed BoosterTM are not covered by warranty.
