Kinorg B20 + A4F

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).

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.
