Hocus Products Axis 1 Wireless Follow Focus system has all kinds of kick-ass features that has us swooning in the LPTG office. The tem at Hocus products wanted to make the Axis 1 simple to operate. There are no silly press/hold/navigate buttons or confusing menus to learn. If its a function, theres a button for it.
Our favorite feature has to be the awesome auto-calibrate feature. The HPM-1 motor isn't picky, just align the 0.8 pitch gear and let it do the rest. The torque sensing system then prevents you from jamming up to the end of the focus throw which can cause damage to the lens and follow focus motor.
The head unit and receiver are constantly communicating with each other via a secure 2.4GHz channel to provide you up to the nano-second information. The hand unit uses the ubiquitous Canon LP-E6 battery and can last about 4-5 FULL DAYS of shoot time!!! The receiver REQUIRES D-Tap power, so be sure you have a capable power source. Check out our Anton Bauer batteries and plates if you need them. The Hocus Axis 1 motor mounts easily on standard 15mm rods and has a 0.8 Mod Drive gear (if you're into that sort of thing.)
The weight of the HPM-1 motor and receiver is 1.05 lbs if you're factoring that into your setup on something like the MoVI.
