Kinorg D25WS Wireless Follow Focus + A4F + B20
D25WS single-axis unit
A single-motor wireless lens control system D25WS (S stands for single-motor) can control 1 motor KM-1 or KM-2. We position this model as a ‘younger brother’ of D25WD.(D stands for dual)
This model has only built-in battery which provides up to 30 operating hours and no possibility to elongate the knob with the plastic extender. All rest functions are the same as D25WD has.
D25WS can be upgraded to D25WD on your request any time within 2 weeks.
Request your local distributors for upgrade.
RGONOMIC DESIGN
Since 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.
MAIN FUNCTIONS
A single-motor version D25WS control only 1 motor KM-1 or KM-2. We position this model as younger brother of D25WD.(D means Dual-motor)
This model has only built-in battery which provides up to 40h. of workout and no possibility to extend the knob with the plastic extender. But all rest main functions are the same as D25WD has. D25WS can be upgraded to D25WD by your request any time. Usualy it takes from 1 up to 2 weeks. Read more at pricing page.

A4F – Fujinon Cabrio FIZ controller
A4F is a 3-axis wireless lens controller designed for the Fujinon Cabrio and S6 lens families with servo engines. The external antenna gives operating range up to 150 m.
A4F can simultaneously work with up to 3 Kinorg hand units – 1-axis wireless follow focus D25WS, 2-axis wireless follow focus D25WD and 1-axis wireless gimbal focus B20. FIZ can be controlled simultaneously. The best approach is to combine D25WD and B20 to cover all three channels of A4F.
A videoclip below demonstrates A4F with B20: the pairing by a press of a button and operating process.
DESIGN
The A4F unit has 3 buttons – one per focus, iris and zoom channel – to confirm pairing with the Kinorg hand units. Each button is also an indicator glowing or blinking depending on the channel mode.
It has 2 connectors – 5.5×2.1mm power port and 20-pins Hirose connector for the connection to the Fujifilm servo engine. Its housing is made traditionally of hardened aluminium alloy and covered black with a polymer paint.
FUNCTIONALITY
A4F can operate FIZ and the Camera RS. Besides that, the standard functions of the Kinorg hand units are applied:
Reverse mode
A-to-B transition with adjustable speed (D25WD/S)
Smooth mode (D25WD/S)
A4F switches on when the power cable is connected. The calibration is not needed – the lens FIZ rings are immediately going to the position according to the hand units knobs.

B20 single-axis gimbal unit
his single-axis wireless follow focus for gimbals controls 1 lens motor – KM-1 or KM-2. Unlike the other hand units – D25WS (single-axis) or D25WD (dual-axis) – B20 has no internal battery and is designed to be powered from an external battery (D-tap by default)
The focus knob of B20 is big enough for reliable and precise operating. The rotation range is limited to 180 degrees relieving from the necessity to twist hands while reaching the limit positions.
The housing is made of hardened aluminium alloy and covered with hard anode layer to protect it from scratches.
UNIVERSAL MOUNT SYSTEM
To provide more flexibility and allow mounting the follow focus on various gimbals, B20 has a standard rosette mount with 1/4? thread. Using a Super Clamp or any similar grip equipment, setup and position B20 the way fits you the most.
MAIN FUNCTIONS
There are 4 buttons on the B20 housing. These are:
Wireless RS, red button
Pair button for connecting with the motor
Auto-calibration
Reverse
Note that the rotation range of the B20 knob is limited within 180 degrees – it is done on purpose so you wouldn’t have to twist your hand. In some cases it is good to have a smaller ratio of the motor rotation speed. To solve this, use the Manual Calibration function of the KM1 and KM2 motors to clip the lens range (see the User Guide to learn more).
