The metabones nikon G to BMPCC Speed Booster allows a nikon G lens to be
mounted to a Pocket Cinema Camera, and in doing so, increases the angle of view
and the maximum aperture. This fantastic piece of kit is ideal for any nikon G
user looking for a wide angle and low light alternative. Not only does it
increase the field of view and lens speed, it also increases the lens' MTF, or
how faithfully the lens transfers detail from the object to the camera sensor.
It also features a clickless aperture ring. A must have for any cinematographer!
