Does anyone know if the nato rail that comes with this follow focus can be used with the RED Komodo 6k top mount holes?
Asked by: Frank
The mount that comes with the SmallRig F40 mini Follow Focus is designed for Smallrig cages. The top mounting points on the RED Komodo are 1/4 20. And the included 15 mm mount is 1/420, so it should work with your camera.

Does this fit the bolex 16 ,rex1-2 model?
Asked by: Anonymous
The SmallRig F40 mini Follow Focus is designed to be a universal follow focus that can be used when mounted on 15mm rods with cinema, mirrorless or DSLR cameras. Considering the design of the Bolex 16 and the age of the camera, the follow focus would not be compatible.
