Like the versatility of a magic arm but hate the inevitability of the threads slipping lose and damaging your accessories? The Walimex Pro Anti-Twist is designed as a safeguard device that works in conjunction with your magic arm to provide a solid mate on both the camera and accessory side. Frankly, I’m not a fan of the traditional magic arm. Whilst their form factor is useful in placing accessories in spaces exactly where you want them, their function is fundamentally flawed by the requirement of two hands for adjustment and the nigh-inevitable occurrence of either end of your arm slipping lose. I have yet to use one that does not suffer from the latter. Unfortunately the physics of having threaded mounts on the same axis of adjustments means it will happen at some point—no matter how hard you tighten both ends. A Solution to Magic Arm Woes? The Walimex Pro Anti-Twist offers a solution that makes the traditional arm a more exciting prospect. The device is split into two parts, each connecting between the magic arm and camera/accessory. On the camera side, the Walimex Pro Anti-Twist offers two points of connection to camera cage and/or cheeseplate. It then receives the magic arm thread, adding a further locking Allen key pin to ensure a solid connection. The dual connection points are right angle to each and offer a degree of adjustment to ensure a more universal fit with a variety of cages/plates. On the accessory side, the same locking Allen key pin is used on the magic arm, plus a rubber gripped base to accompany the single 1/4″ male thread ensuring the mount remains universal but offers a much more solid mate. With a strong connection to both camera and accessory, the magic arm can now be used much more freely without risk of the inevitable slip. Personally, I prefer to use friction based mounts for monitoring accessories as these require only one hand for adjustment. However, other accessories that need to stay put (sound recorders, microphones, wireless transmitters, etc) could all benefit from a system like this.Read more
Infinity Arm is a versatile, heavy duty magic arm. Its interchangeable ball joint allows a selection of mounting options as well as a quick release system for switching between applications. The Infinity Arm surfaced on a few blogs earlier in the month, but with the Kickstarter still in mid flow and their target not yet reached, I thought it was worth bringing to the attention of anyone whom hasn’t yet seen it. The form factor of a magic arm is fantastic, they enable you to get a variety of accessories/cameras to where you want them, quickly and with the turn of just a single knob. However, they’re limited in application due to the payload they usually carry. The Infinity Arm is made of high strength aluminium, utilizing a rosette joint to enable a sturdy lock. Check out the stress test below: Whilst it currently has no official payload figures, you can see from the above video it’ll take over 10lbs. A couple of these at either ends of your setup would be a great solution for those hard to reach, unique camera positions. In addition, the current prototype measure 8.5″ long without joint tips. A nice feature is the interchangeable ball joints. when loose, you can quickly change out the joints of the Infinity Arm, meaning you can switch between setups very quickly (as long as you have pre-mounted ball joints on other aspects of your setup), as well as alter the size or type of the thread. Infinity Arm currently offer a 1/4″-20 male thread, cold shoe and GoPro mount. (Future mounts will include: custom clamp, 3/8″, baby pin, female 1/4″-20 and 3/8″ with more to come). I’d like to see 15mm rod added to this list, which would match up nicely with Zacutos Zamerican accessories. $159 would start you off with an Infinity Arm package, although pledges start much lower if you’re just looking to help the project along. Check out the Kickstarter page for more information on rewards.Read more
