Matthews Infinity Arm Overview

Supporting up to 32 lb, the Matthews Infinity Arm is a super-strength, modular cine arm that may highly simplify your on-set workflow. Supporting nine different accessory tips via secure ball sockets on both ends, it's designed to serve you well across the gamut of grip applications, such as mounting cameras, lights, and monitors underslung from C-stands, booms, or speed rails. Two 1/4"-20 male accessory tips and a 3/8"-16 male tip are included, and a soft carrying case is also supplied for storing the arm and additional tips, providing room for growth.

The Infinity Arm is made of two identical sections and measures 9" from end to end without tips. Its strength is the result of superior materials of construction and machining processes. It's built out of steel and aircraft-grade aluminum, and it features a 60-section radial rosette in the center machined with a focus on getting a good grip at every section. The Infinity Arm will reliably hold 15 lb when in a fully horizontal position—which is naturally the least strong position—and up to 32 lb when you start adjusting it to more angled positions, with a 90° angle being its strongest configuration.

The rosette mechanism is adjustable by loosening/tightening a large knurled, easy-to-handle dial on the side. The supported accessory tips are fully 360° rotatable. On top of everything, the Infinity Arm has a nice appearance and is neither overdone nor underdone in its aesthetic design. It is finished with military-grade black anodized and proprietary electroless nickel-phosphorus. And, although designed with a focus on grip applications, it can also be used for standard camera-mount and rig-mount uses.

  • 1/4"-20 female (429626-1)
  • 1/4"-20 male (429626-2)
  • 3/8"-16 female (429626-3)
  • 3/8"-16 male (429626-4)

Matthews Infinity Arm Reviews

It's strong but it's too heavy and not versatile

By Antoine
Rated 2 out of 5

Although this arm is strong, it's not suitable for attaching to a camera to hold a monitor, as I intended to do primary. It's way too big and too heavy Plus it's hard to manipulate, you need to unscrew it almost entirely to move it so you can't do that in a rush... as said before the quick lock are hard to remove This arm is definitely not suitable for a camera monitor. But I'm sure it will be good for other uses. For now, I use it to hold an umbrella on my focus monitor.

Worth it!

You can buy all the cheap adjustable arms but you will be disappointed! This it top notch!

question

Does this arm allow for the simultaneous use of two small video cameras? I'm envisioning something that would mount on top of a stable tripod allowing me to shoot with two video cameras at the same time (one for a wide shot, the other for close-ups). Thanks.
Asked by: John M.
John M is correct but you could mount a bar to hold two cameras on one end of the Infinity Arm depending on their size and weight.

Unfortunately at this moment Matthews does not have an option for adding an adapter with locator pins.

And i also want to know the tendency that the rosette was worn out by its friction. How long does the rosette part life?

With proper use it will last for a very long time. It is constructed out of hardened tool steel, specifically chosen to provide many years of rock solid support.
