As the locking knob is tightened, the friction in the two ball and socket joints and central rotary joint get progressively tighter. Rather than a sudden “clamped or unclamped” locking system, the variable friction system allows the arm to be positioned approximately, and then tweaked (under some resistance) before finally setting the final lock by fully twisting the locking knob.
The 15mm Quick Release Clamp is quick release and can be snapped to your support rods without removing any other components. This makes it very easy to add or remove the follow focus without breaking down your kit.
The part is machined from lightweight aluminium alloy, using CNC techniques and hard anodised in black to provide a finish which is highly durable, and very resistant to scratching.
