Metabones Nikon G to Micro Four Thirds Speed Booster XL 0.64x Adapter
The Metabones Speed Booster XL 0.64x Adapter is a new Micro-4/3 mount adapter designed exclusively for the Panasonic GH4 designed exclusively for the Panasonic GH4 and other Micro Four Thirds cameras with a magnification of 0.64x.
Unique Features
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.
Advance Performance
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.
