Metabones Speed Booster BMPCC Micro 4/3 to CANON EF Speed

The CANON EF lens for Blackmagic Pocket Cinema Camera Speed Booster from Metabones adapts CANON EF lenses to Micro Four Thirds mount, while using custom optics to increase the angle of view and maximum aperture of the lens. It is designed specifically for the Pocket Cinema camera Blackmagic Pocket Cinema camera and features built-in electronics that allow you to set the lens aperture using the camera' s controls .

The Speed Booster works by reducing the image circle of the EF lens to better fit the most sensitive sensor CANON EF lens to better fit the smaller sensor of the Pocket Cinema camera Blackmagic Pocket Cinema. This has the effect of making the angle of view of the lens 0.58x wider or, in other terms, reducing the crop factor of the camera from 3.02x to 1.75x.

When the Speed Booster concentrates the image circle of a lens, the brightness of the image is increased by 1 2/3 stops. This produces a maximum output aperture of f / 0.74 when using an f / 1.2 CANON EF. In addition to lens speed and angle of view, the Speed Booster also increases the lens 'MTF, or how faithfully the lens transfers object detail to the camera's sensor. These MTF increases are seen in the corners as well as the center of images.

To reduce stress on the MFT' s pocket camera mount , the Speed Booster includes a removable Arca-type tripod foot to help support the weight of the adapter and lens. In addition to being compatible with Arca-type quick release heads, it also has a 1/4 "-20 threaded hole for mounting other tripods, rigs, or quick release plates. The built-in electronics are powered by the camera body, so no additional power supply is needed. To reduce your camera 's battery consumption , the Speed Booster uses an efficient switching power supply , which continuously switches between on and off, only supplying power when you need it.

Note: This Speed Booster is not compatible with the GH4 or other camera mounts PANASONIC GH4 or other MFT mount cameras. This is for use with Blackmagic Pocket Cinema Camera only. When the Speed Booster is used with other MFT mount cameras, it's rear element may cause damage to the camera.

Supported

EF lenses
Image stabilization (IS) lenses
Electronic manual focus ( e.g. EF 85mm f/1 .2L II and discontinued EF 50mm f/1 .0L)
EXIF ( focal length , aperture, zoom range )
Distance and zoom display on BMPCC camcorders (Requires remote lens support information )
Contax N-mount lenses modified to CANON EF by Conurus
Contax adapter 645 NAM-1 modified for CANON EF by Conurus
SIGMA, TAMRON y TOKINA CANON EF mount lenses

Note: Third party zoom lenses may have to be registered in the Speed Booster first in order to detect their maximum aperture, zoom to maximum and minimum focal length, then turn off the adapter to store the settings in the Speed Booster ' s non-volatile memory.

not supported

Autofocus
EF-S lenses
Lens correction, such as peripheral shading, CA and distortion
Focus confirmation "chip" (e.g. dandelion, dandelion)
M42 Screw mount adapters (Some illicitly performed M42-Screw mount adapters may short the Speed Booster 's electronic contacts and cause damage to the Speed Booster and/or camera body)
Stack no Metabones / no Conurus mount adapters on the side superior

List of manual focus lenses requiring modification for use with Speed Booster
Many manual focus lenses have rear protrusions (spikes, levers, other appendages) that can damage the optics and/or Speed Booster housing. They need to be modified before they can be safely used on Speed Booster via third party adapter rings. Check and make sure that there are no rear protrusions of the adapter/lens combination before using the Speed Booster. The following is an incomplete list of lenses known to be incompatible without modifications

LEICA R

Super-Elmarit R 15mm
Elmarit R 28mm f / 2.8
Elmarit R 35mm f / 2.8
Summicron R 50mm f / 2
