MFC-3F Follow Focus with adjustable friction

MFC-3F Follow Focus with adjustable friction

The "F" in MFC-3F stands for adjustable friction strength.

The unique feature of the new follow focus system MFC-3F is that the focus knob and drive gear consist of only one part, there is no transmission in the new MFC-3F. This is a direct drive, and because of the elimination of internal gears, there can never be any difference in the motion going in and going out, making it 100% playless, Vocas can guarantee you that!

This design also results in the MFC-3F having a 1:1 'transmission' ratio making it ideal for lenses with a small focus throw such as DSLR lenses and smaller cameras with integrated lenses. Additionally, because of the elimination of internal gears the lifespan of the product is increased extremely.

The unique shape of the drive gear teeth is what makes this all possible. These specially shaped teeth can push the gear ring of the lens up or down when rotating the focus knob the same way a camera operator is used to.

The MFC-3F has one additional feature over the standard version, namely it has an adjustable friction build in. Rotating the red dial on the focus knob allows you to fine tune the internal friction of the MFC-3F to your own preference.

This follow focus includes the Vocas flexible gear ring, with 2 movable stops.
For use with cilindrical lenses with a focus barrel diameter between 40 mm and 110 mm. (0500-0295).
