The Focus Shifter — A Simple Lens Mountable Follow Focus

The focus shifter -- which, for now, is also going by the name "lens shifter" -- is a simple, lens-mounted, adjustable follow focus that works by attaching to the focus ring on lenses between 56 and 98mm in diameter. Using the attachable marker board you can then mark your focus and transition points in advance, shifting between them with ease when the time comes.
