Metabones Nikon G to BMPCC4K Speed Booster XL 0.64x (Black Matt)

The Metabones Nikon G to BMPCC4K Speed Booster XL 0.64x (Black Matt) allows a full-frame Nikon G lens to be mounted onto a Blackmagic Design Pocket Cinema Camera 4K MFT-mount camera. While doing so, the adapter's optics help to maximize the connected lens's apparent angle of view while providing a 1.33-stop increase for the camera over the lens's aperture range.

The BMPCC4K Speed Booster ULTRA 0.71x and XL 0.64x are similar to the standard M43 Speed Booster adapters 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.

The BMPCC4K Speed Booster XL 0.64x reduces the crop factor of the BMPCC 4K camera from 2.02x to 1.29x.

Metabones Nikon G 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.

Makes the lens 0.64x wider.

Patented 7-element/4-group optical design by Caldwell Photographic in the USA.

If a lens intended for 35mm film or similarly-sized full-frame camera sensors is connected to a camera with a Micro Four Thirds sized sensor, it would project an image larger than the Micro Four Thirds sensor was built to accept. Able to capture only the centre portion of the projected image, the effective angle of view of the lens would be narrowed, creating an in-camera "crop factor." The T Speed Booster XL 0.64x adapter condenses the light from a lens designed for 35mm film or "full-frame" camera sensors and projects it onto a Micro Four Thirds sensor. This allows the Blackmagic Pocket Cinema Camera 4K with a Micro Four Thirds sensor to utilize more of the light gathered by a connected lens, which effectively reduces the crop factor while making available to the sensor an additional 1.33-stop of light for each of the lens's f/stop settings.

Quality Construction

This adapter is constructed from aluminium for durability while minimizing weight and its mounting rings are made with brass to further prevent wear and tear and a detachable tripod foot is included and features 1/4"-20 threads as well as compatibility with Arca-Swiss tripod heads.

Internal flocking to reduce internal reflection.

Rubber gasket protects M43 mount connection from dust and moisture.

Aluminium alloy and brass construction with chromium plating.

Satin surface finish.

Detachable tripod foot compatible with Arca Swiss Style ball head or attach to quick release plate by a 1/4"-20 screw.

The tripod foot is tailor-made to match the exact height of the BMPCC4K camera body.
