At the NAB Show, Libec shows us the ALLEX system. A line of products or complete kit designed to work seamlessly together so that you don't have to struggle with what tripod works with which video head and how that all comes together with a video slider.
The ALLEX H Fluid Video Head uses a drop in style plate, something many shoulder rig shooters have a preference over instead of the sliding systems. The head combines both a 75mm bowl + a standard 3/8" flat base mount. When used on the Libec ALLEX T tripod, the bowl allows you easily level your system, and the flat base will thread easily to the ALLEX Slider.
The ALLEX S is a 30" Slider using 8 bearings surrounding the rail. The slider features a friction knob for drag, brake knob, along with adjustable legs / feet. Beneath the slider is a similar 75mm bowl to fit directly to the ALLEX T Tripod, but also offers a 3/8" thread flat base mount.
The ALLEX T Tripod is very sturdy two-stage all aluminum, 75mm bowl mount, with mid level spreader, and articulating feet. The Tripod weighs approximately 5.5 lbs.
