Photo Gear News has a hands-on video of Waterbird systems' Multi-Slider, which the company touts as a world's first. The slider can easily go from linear to curved, and users can make fine adjustments to the curve using an allen wrench. Each segment of the track has a tripod mount in order to keep things stable.

An included motor moves the camera smoothly along the track, while a controller lets the photographer define the positions, speed and acceleration for camera movement. The controller can also be controlled remotely from a mobile device.

The Multi-Slider comes in three sizes: 80cm, 120cm and 150cm, and Waterbird can produce custom sizes, as well.

Pricing has yet to be announced.
