The Metabones T Speed Booster Adapter XL MB-122 Canon EF to Micro Four Thirds is designed exclusively for the Panasonic GH4 and other selected Micro Four Thirds cameras (refer to the below specifications), with a magnification of 0.64x. The T 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 the Micro Four Thirds format.

The T 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.

Note: Auto focus function is not supported when using this adapter. There are a number of Micro Four Thirds cameras that are not supported due to mechanical clearance issues. There is a minor interference with the protective shutter cover, and although slight contact with the shutter cover appears to have no effect on the functioning or cosmetics of either the camera or the Speed Booster, Metabones cannot support these combinations due to possible risk of damage.
