The Speed Booster XL 0.64x Adapter for Full-Frame Canon EF-Mount Lens to Micro Four Thirds allows a full-frame Canon EF-mount lens to be mounted onto a Micro Four Thirds-mount camera. While doing so, the adapter's optics help to maximize the connected lens's apparent angle of view while providing a 1.3-stop increase for the camera over the lens's aperture range.

The Speed Booster XL 0.64x uses an advanced 6-element optical design to achieve extraordinary optical performance at apertures up to an incredible f/0.80, a new record for Micro Four Thirds format. The new Speed Booster XL 0.64x reduces the full-frame crop factor of the Panasonic GH4 from 2.0x to 1.28x, thus effectively transforming these cameras into APS-H format. When the GH4 is used in Cinema 4k video mode the horizontal full frame crop factor is reduced from 2.34x to 1.50x, thus effectively transforming the GH4 into a super-35 format 4k cine camera. In addition, the speed of any attached lens is increased by 11/3 stops, with a maximum output aperture of f/0.80 when an f/1.2 lens is used. For example, a 50mm f/1.2 becomes a 32mm f/0.80, which is the fastest aperture available for full size Micro Four Thirds format.

This adapter is constructed from aluminum alloy for durability while minimizing weight and its mounting rings are made with brass to further prevent wear-and-tear. Inside are six lens elements in four groups that are designed to provide optical clarity as well as color fidelity, and a detachable tripod foot is included that features a 3/8" threads as well as compatibility with Arca-Swiss tripod heads.

The Speed Booster XL 0.64x Adapter for Full-Frame Canon EF-Mount Lens to Select Micro Four Thirds-Mount Cameras supports electronic communication between an attached camera and lens. Although the attached lens must be manually focused while using the adapter, aperture settings can be can be controlled from the camera. Also, if an attached lens is capable of generating EXIF metadata when used with a directly compatible camera, the Speed Booster XL 0.64x Adapter for Full-Frame Canon EF-Mount Lens to Select Micro Four Thirds-Mount Cameras is designed to allow that information to be saved along with image files generated with a combination of the lens, a compatible Micro Four Thirds-mount camera, and the adapter.

This adapter can be mounted onto the Panasonic DMC-GH4, GH3, G3, G5, G6, G10, GF3, GF5, GF6, and GX1 Mirrorless Micro Four Thirds Digital Cameras; the Olympus PEN E-PL7 Mirrorless Micro Four Thirds Digital Camera; the Blackmagic Cinema Camera with Micro Four Thirds mount; and the Blackmagic Pocket Cinema Camera.
