Does bmcc switching zoom ring have the function of amplifying photosensitive elements? DCC bought a Nikon port, saying that it can turn Nikon lens, and the coefficient is

The focal length conversion multiple of BMCC is ≈2.3, and the focal length of your lens multiplied by the conversion multiple is the actual focal length of the current lens. Of course, the perspective relationship of the obtained picture is the same as the focal length marked by the lens on the Quan Huafu machine, but the picture is cut ~ Note that BMPC4K is over 35mm, not 35mm Quan Huafu, and the focal length conversion multiple is ≈ 1.4.
