E-Image EI-A75 Ultra Arm - High-Payload Articulating Monitor Mount

The E-Image EI-A75 is a professional-grade articulating magic arm engineered to securely mount heavy production monitors, wireless video transmitters, and compact LED fixtures directly to cinema camera cages.

Built for the Demands of Modern Production

When rigging a cinema camera, the reliability of your accessory mounts is just as critical as the camera itself. Sagging monitors and slipping wireless transmitters can ruin a take, throw off your operating balance, or damage expensive components. The EI-A75 solves this by offering an exceptional payload-to-weight ratio. Weighing only 200g, this dual ball-joint arm securely locks down up to 5kg of payload, easily accommodating a fully rigged 7-inch high-bright monitor with dual V-Mount batteries without creeping under torque.

The arm's central locking mechanism provides simultaneous tension control over both articulation points, allowing camera operators to adjust viewing angles rapidly between setups. By utilizing precision-machined ball joints and a heavy-duty tightening lever, the arm eliminates the micro-vibrations and gradual drooping commonly experienced with standard friction arms during handheld, Steadicam, or gimbal operation.

Integrated 1/4"-20 and 3/8"-16 mounting points with knurled thumbwheels ensure rapid, tool-less deployment onto standard cheese plates, camera cages, or top handles. This streamlined, 15cm low-profile design keeps your rig's center of gravity tight and manageable, making it an essential grip component for fast-paced documentary shoots and high-end commercial sets alike.

Production FAQ

Will this arm support a 7-inch production monitor equipped with wireless receivers and batteries?

Yes. With a 5kg (11.0 lbs) maximum payload capacity, the EI-A75 is designed to maintain a rigid lock on fully built 7-inch monitors and their attached power sources without slipping or drooping under the added torque.

Can I adjust the angle of my monitor with one hand?

For safety, you should support the weight of the monitor with one hand while loosening the central locking lever with your free hand. The single-lever mechanism instantly releases tension on both ball joints simultaneously for rapid repositioning.

Does it mount to standard Arri-style cages?

The EI-A75 features standard 1/4"-20 and 3/8"-16 threaded ends, allowing it to screw directly into any standard cinema cage, top handle, or cheese plate equipped with corresponding receiving threads.

Is it suitable for high-vibration environments like car rigs?

Yes. The machined ball joints are designed to provide maximum friction under tension, virtually eliminating micro-slippage during vehicle mounting or aggressive gimbal maneuvers when properly torqued.
