The Alzo Video Smoothy Radius and Linear Video Slider was first shown at NAB 2015, and they wanted to send one out for me to test drive. The slider can track in a straight line (linear) and then can be reassembled into a curved (radius) track for keeping a subject in frame and in center. Here's a little overview.

Riding on a track of this design requires careful hands to prevent any micro jitters. In some cases my shaky hands transferred slight vibrations, but after running a bit of post image stabilization the footage was fine.

Alzo Smoothy Radius and Linear Video Slider

The Alzo Radius Linear Slider is limited to small lightweight camera and lens combinations, and also requires you to be at least 6 feet away from your subject to use the Radius effectively. At 4 feet long it might be a bit too long for constant travelers. Overall I think it's certainly a unique design, and we were able to get some decent results. But what do you guys think about the new Alzo Smoothy Radius and Linear video slider? Leave your comments below.
