Hands on with the Matthews Infinity Arm

The versatility is where the Infinity Arm shines

This past Cine Gear I was walking around the lot checking out the wares and made a stop by the Matthews tent to see what they had going on. A bunch of the products that I’ve talked about in my Gear + Beers and Dutti Dolly articles were on display, so nothing caught my eye at first. I was about to move on until I spotted the Infinity Arm. Everyone wanted to talk about the Infinity Arm, and for good reason. 


Cine arms are a mainstay of the production environment. Most often you’ll see a Noga arm holding a monitor or EVF to the camera body in some capacity. I didn’t know this, but Noga arms are primarily made for industrial applications, and the film industry stole them. I do love re-purposing products like that, but as a student of Alton Brown’s I hate a unitasker. I’ve used my Noga arm to mount a monitor to my camera cage, of course, and I’ve even used it to attach my Sony X3000 to it to get footage for that aforementioned Dutti Dolly review, which it worked great for. Really, anything lightweight with a ¼”x20 plug on the bottom will mount just fine. But what if you want more from your cine arm?

Enter the Infinity Arm. Matthews’ offering takes all the hallmarks of a traditional cine arm and dials them up to 10. The biggest thing I noticed right off the bat was the rosette in the middle. Where other arms use friction to hold everything together where the two arms meet, the Infinity Arm locks both arms together with a rosette-type connector which doesn’t allow for any slippage at all. And I mean none. The second thing I love about it is that the “handle” you use to tighten it is a wheel instead of a handle. Oftentimes I’ll find myself putting my Noga arm in a certain position, only to find that the handle will hit something while turning. It’s not the end of the world, as you can pull it up, rotate it back a bit, and keep tightening that way (like a ratchet), but it gets annoying and speed is everything. Also, the wheel is a knurled piece of aluminum, whereas the Noga’s tightening lever is plastic. In fact, the entire Infinity Arm is aluminum and steel, which adds some weight but also rigidity and durability. It feels indestructible. 

Going back to the tightening mechanism, the traditional Noga arm uses a cable system internally that pulls the “balls” towards the center. Eventually, this will stretch out and you’ll need to replace the entire thing. Before this ultimate failure, it will, by definition, get weaker and weaker. In contrast, the Infinity Arm uses a rod system that pushes outwardly, giving you infinitely more time with the product.

At this point, I thought “oh cool, so it’s twice as expensive as my Noga arm but sturdier and I suppose more ‘enjoyable’ to use.” That meant it was nice, but not enough to really sell me on it. That was until I noticed that the box the arm came in had all these little accessories in bags. Upon further investigation I discovered why they called it the “Infinity Arm”: The tips are replaceable.



This was a revelation. With a quick press of the little red button below the collar, you release the current head and can swiftly plug in a new one. They’ve got ¼”x20 Female and Male heads, a ⅜”x16 head, an aluminum GoPro mount, a ⅝” female (baby) pin and receiver tips, a Mini Matthelini Clamp, a Coldshoe mount, and just in case you need ultimate stability: a cheese plate head. I started running around trying to see what I could mount to what and I was not disappointed.

I immediately tried setting up my “podcast” rig (seen at the top), which is one C100 mounted to another C100 with a longer lens so I’ve got a wide and a close up on one tripod. Usually, I have to use a lighter B camera and be careful with walking around the setup so the floor doesn’t impart shakes into the Noga-mounted cam, but not so here. Solid as a rock. What if I forgot a tripod but had a light stand or something? No problem. C-Stand camera mount? Done. Just a pole? Easy. I found myself looking all around my house for things I could mount a camera to, just in case that came up in the future. I knew I had gone too far when I was skateboarding around with the camera mounted to the skate deck, thinking about if it would work on a surfboard. The clamp and pins alone are a big addition as that allows you to essentially mount a light, modifier, camera, or otherwise to almost anything.

Matthews says the Infinity Arm can hold up to 15lbs and I would argue that they may be underselling it, but 15lbs is a totally safe bet. Also, in case you were wondering, it’s sort of difficult to get the tips out of their collars. By that I mean there’s absolutely no way for you to do it accidentally; you have to unscrew the middle knob almost all the way out before the little red buttons will depress far enough for you to remove the tip. That’s good for your peace of mind.

When I set out to write this review I thought it would be a Noga vs Infinity type situation, but I was wrong. That comparison is unfair. They’re barely even in the same ballpark. You don’t compare a Focus to a Ferrari in earnest. 

So is it worth paying twice as much as most competitors for an Infinity Arm? I’d say yes. While the build quality is top of the line, the versatility is where the Infinity Arm shines. I could see myself keeping two or three in my kit at all times as long as I had a nice selection of tips along with it, which vary in price between about $30 and $70. While that’s still a little pricey for a few pieces of aluminum, that’s less than buying an entirely new piece of equipment to do the job. While some unitaskers have their place, the multitasker is king in my book.

100% agree. I had a cheaper arm that was difficult to keep tight and just didn’t inspire confidence. Not wanting my Odyssey 7+ to fall, I spent the money for the Infinity Arm. What a difference! Also, at Cinegear 2016 I had the pleasure of speaking with the designer and letting him know what a good product it is. I did complain about the knurled knob sometimes hurting my fingers when getting it tight. They joked about my lack of manliness which I took in good fun .
