D25WS single-axis unit

D25WS single-axis unitA single-motor wireless lens control system D25WS operates 1 motor KM1 or KM2. We position this model as a ‘younger brother’ of D25WD.

This model has a built-in battery which provides up to 30 operating hours and no possibility to elongate the knob with the plastic extender. Apart from that, all the functions are the same as the D25WD has.

D25WS can be upgraded to D25WD at your request any time within 2 weeks.

D25WS single-axis unit


D25WS single-axis unitSince 2011, we’ve tried half a dozen of various modifications of the hand unit. The D25W family takes its beginning from clay and wooden prototypes – the first step was to choose the most convenient shape. It took about a month to choose the best one and check it with future users. To eliminate accidental pressing, all the functional buttons are out of contact with the holding palm and fingers – namely, on the front and top sides. To make the hand unit really intuitive, we refused to use LED screens with sophisticated menus. We just took a proper account of the interaction between focus pullers and a wireless follow focus and implemented it in a minimalistic intuitive design.
