DigitalFoto has brought the second version of its IRON damping magic arm to IBC 2026, now in 7in and 11in lengths with a 5kg (11 lb) vertical payload, swappable F22, NATO and thumbscrew heads, and a new Sabertooth clamp. We spoke to Ivan Kwok at the DigitalFoto booth about how the damping joint works, the mounting options, and the safety features built into the quick release.

We’ve previously looked at the first damping arm from the company, the IRON-311QD, and DigitalFoto has since built the idea out into a small range of arms, heads and clamps. Ivan, who also walked us through the company’s first V-mount battery at the show, described the lineup as a family of arms rather than a single product. The two lengths share the same core design, and the difference between the 7in and the 11in arm is the length itself. Let’s take a closer look.

Damping instead of teeth

The main point of the IRON arms is the joint. A conventional magic arm relies on a toothed mechanism, so repositioning a monitor or light means releasing the knob, moving the arm, and locking it again. The IRON arms use a damping design instead, which holds the arm under constant resistance. The user moves the arm into the new position and it stays there, without the release and lock steps in between. Ivan described this as the main time saving for content creators who adjust a monitor or accessory many times during a shoot.

Without teeth, the movement is continuous rather than stepped. A toothed joint tends to click as it moves and can settle slightly past the intended position, while the damping joint allows small, precise corrections.

Payload and drift

According to Ivan, both lengths carry the same load: 5kg (11 lb) vertically and 3.5kg (7.7 lb) horizontally. The tension is adjustable, and there is no fixed number to dial in for a given weight. If the camera or monitor is heavier than the arm is set up for, the user tightens it a little further until the arm holds its position. Ivan said this is judged by feel rather than by a scale on the knob.

Around 80% of the arm is aluminum. The parts that carry the load and determine durability are stainless steel, which Ivan named as the key to the payload rating and long-term quality.

Three heads and a quick release

The standard configuration uses a thumbscrew head, which many cinematographers still consider the safer option. To stop the mounted device from twisting, DigitalFoto has added retractable locating pins to the SmallHD standard.

The second option is the F22 quick release. Unlocking the lever and pressing the release lets the user take the plate off the arm, and the plate itself carries two retractable ARRI locating pins on top. That head can also be exchanged for a NATO rail version, and DigitalFoto offers NATO accessories to go with it.

The quick release has two safety features. An anti-drop lock on one side holds the plate if the user forgets to tighten it, and a retractable pin on the other side acts as a second catch. Ivan called this a double security, which matters with a monitor or wireless transmitter mounted above talent or over a gimbal operator.

The heads are not fixed to the arm. A user who bought an arm with one head and later needs another can order the top piece separately and swap it with an Allen key, so there is no need to buy a second arm to change mounting systems.

The Sabertooth clamp

Alongside the arms, there is a clamp named after the sabertooth tiger. According to Ivan, the design is meant to bite down on a tripod leg or pipe so the tubing can’t slip out of the jaws, rather than relying on a single clamping surface. The clamp can also stand on a table and act as a small base, turning the arm into a free-standing support for a monitor or light. The clamp combines stainless steel with aluminum parts, including exposed steel screws.

Price and availability

DigitalFoto quoted around €200 for the 11in configuration and around €158 for the 7in version at the show. For more information, please visit the DigitalFoto website.
