Comparing a set of Nikon f/1.8 prime lenses (20mm, 50mm and 85mm) on a full frame Nikon D610 and a Blackmagic Pocket Cinema Camera + Metabones Nikon G to BMPCC Speed Booster.
The Speed Booster reduces the BMPCC Crop Factor from 2.88x to 1.75x and increase the f/1.8 speed to f/1.0 thus making the FX 50mm f/1.8 a 85mm f/1.0 equivalent.
