A simple camera slider modified to have a manual geared belt for finely controlled camera moves in stop frame animation. It has a tensioner but works best when the slider is level. It has adujustable feet. Inch and milimeter guide marks. 1 meter travel. Could be mounted upside down. Works well with a DSLR camera mounted on a ball head. The joy of a manual slider is there's no faffing around with setting up and programming moves. Great for freestyle animation if you're following a character or object that's changing speeds and direction for example. Collection preffered, London E9. I could post but at extra cost as I'd need to obtain the right size tube to post it in.
