Pre-orders for Parallax will begin on December 8th, with shipping beginning withing around two weeks or less after that. The Parallax page will be launched within the next couple days.
When Parallax is first released, it will be the version for the CineSlider, and will be 3' long, but will be able to mount to all three lengths.
We will follow up shortly after with versions for mounting to the Pocket Dolly rail, that will work with regular and Basic Pocket Dolly, Blooms and Stealth units.
Because of the rails being different between the CineSlider and Pocket Dolly sliders, the Parallax has to be mounted to the sliders differently.
