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.
