K&F Magic Arm Mini with Arri Pin 1/4″ and Cold Shoe Heads | KF31.098

Position your accessories exactly where you need them

The K&F Concept KF31.098 Magic Arm Mini with Arri Pin is designed for hybrid shooters and content creators who need to reposition monitors, lights, or microphones quickly between setups without dealing with multiple lock points. Mount the cold shoe base directly onto your camera, cage, or top handle, then attach your accessory to the 1/4-inch threaded mounting point at the opposite end. The dual ball-head design allows independent adjustment at both ends, making it easy to position the arm around a lens hood while separately angling your monitor, light, or microphone exactly where you need it. A single thumb lever locks both joints simultaneously for faster mid-shoot adjustments, while the Arri positioning pins help prevent unwanted rotation during handheld use. Weighing just 105g and measuring 12.2cm long, it stays compact enough for daypack carry while supporting loads up to 1.5kg, suitable for most compact LED panels, field monitors, and shotgun microphones used in run-and-gun setups.

Dual ball head for multi-axis positioning
The dual ball-head design gives you full 360° rotation at both ends of the arm, unlike single-pivot arms that only tilt forward and back. This matters when you're mounting a monitor on a cage for waist-level shooting on a gimbal, then need to reframe at eye level for tripod work without remounting anything. Each ball joint rotates independently, so you can angle the arm to clear your camera's geometry, then separately adjust the accessory to face your subject. The single thumb lever locks both joints simultaneously, faster than arms requiring separate adjustments at each end, which matters when you're working alone and need to reframe quickly between takes.

Arri pins prevent rotation under load
The 1/4-inch positioning screw includes retractable Arri-style locating pins that seat into matching holes on camera cages and top handles. Once seated, the pins prevent the arm from rotating loose during handheld work, the most common complaint about budget arms that rely on friction alone. Mount a fill light on a cage for an interview and trust it stays aimed at your subject through multiple takes, rather than drifting out of position every time you adjust the camera angle. The pins are retractable, so the arm still functions as a standard 1/4-inch screw mount on devices without Arri holes, they simply add anti-rotation security when your cage does have them.

Cold shoe and threaded mounts on both ends
One end features a universal cold shoe mount designed to slide directly onto a camera, cage, top handle, or any standard cold shoe receiver. The cold shoe base also includes an integrated 1/4-inch threaded hole, allowing the arm itself to be mounted to threaded rigging points when needed for alternative setups. The opposite end uses a 1/4-inch positioning screw for attaching accessories such as LED panels, microphones, field monitors, or other equipment with a standard 1/4-inch threaded mounting point. This combination provides flexible mounting options across camera cages, gimbals, tripods, and handheld rigs without requiring additional adapters or secondary support arms.

1.5kg load capacity for typical run-and-gun accessories
The arm supports a combined load of 1.5kg across both ends without sagging or slipping, comfortable territory for a compact LED panel, 5-inch monitor, or shotgun mic. This covers typical vlogging rigs where you're running a shotgun mic on the cold shoe and mounting the arm itself to a camera cage, or attaching a small fill light for indoor interviews. The load capacity excludes heavy battery-powered LED fixtures or large external recorders, but those accessories typically require heavier cinema arms anyway. For hybrid shooters working with mirrorless cameras and compact accessories, 1.5kg is the practical working range.

O-ring damping for controlled adjustments
The rotating ball bodies use O-ring damping to add controlled resistance during adjustment, so the arm doesn't flop to a new angle the moment you loosen the lock. This gives you fine control when positioning a monitor or light, instead of overshooting and having to readjust three times. The damping holds position even when the thumb lever is slightly loose, so you don't need to crank it down hard enough to risk stripping threads. If you're dialling in the exact angle for a fill light on a product shoot, the O-ring damping makes the adjustment feel smooth rather than loose or sticky. Two replacement O-Rings are included with this item.

105g aluminium alloy for compact rigs
At 105g, the arm adds a monitor or mic to your setup without the weight penalty that forces you to leave accessories at home. The aluminium-alloy construction keeps the arm light enough to mount on a gimbal or compact rig without greatly throwing off balance, critical for travel vlogging setups that need to fit in a daypack and still include a shotgun mic and small LED. Fold it into a Z to get items as low as 5 cm or stretch it all out vertically and get as high as 12 cm from the same flexible body. The compact dimensions mean the arm actually travels with you instead of being left at home because it's too bulky to pack.

The K&F Concept Magic Arm Mini with Arri Pin 1/4" and Cold Shoe Heads is a practical upgrade for hybrid shooters who need to reposition monitors, lights, or microphones quickly between setups without the rotation drift that plagues cheaper arms. With dual ball-head articulation, Arri pin anti-rotation, and a single-lever lock, it's a reliable tool designed to support modern run-and-gun workflows. Order the KF31.098 today and take control of your accessory positioning with confidence.

Frequently Asked Questions

Frequently Asked Questions:
Q: Will this arm work with my existing camera cage if it doesn't have Arri pin holes?
A: Yes. The Arri pins are retractable, so the arm functions as a standard 1/4-inch screw mount on any cage or device with a 1/4-inch threaded receiver. The pins simply add anti-rotation security when your cage does have the matching holes, they don't prevent compatibility when it doesn't.
