At IBC 2015 Dutch manufacturer Vocas announced new wooden handle with Lanc control and a prototype of self-adjusting double follow focus.
   

Vocas wooden handle incorporates a Lanc control and is compatible with Canon C-series cameras and the FS7, A7s and A7R cameras from Sony(they have yet to test it with the FS5 but assume it will work in a similar way to the FS7). The package includes lanc control cable.

Vocas also have a prototype self-adjusting double follow focus, which features an arm with adjustable pressure to maintain steady contact with the lens gear. This will be especially useful for use with stills lenses not originally designed for use with a follow focus as it can sometimes be difficult to maintain consistent contact between the gears. The whole follow focus unit is expected to ship at the end of the year.
