Product Description


The Metabones Nikon G to MFT mount Speed Booster adapter caused massive waves in the professional video production world as they not only help to mount non native lenses to your camera body, they also increase the width of the image by 0.58x and gives you an extra stop of light! This reduces the crop factor of the BMPCC from 2.88x to 1.75x, and produces the largest aperture optics currently available, with a maximum output aperture of f/0.74. It achieves this by adding a precision, high quality optical element between your lens and camera body that's housed in the body of the Speed Booster.
