Can a 6 Inch Slider (15cm) be a working tool for videographers? Turkish gear maker Edelkrone says yes and putting their development money where their mouth is. Edelkrone just introduces Slider One, a tiny slider that fits right at the top of a tripod.
The Slider can be a great companion if you know how to use those 6 inches. (I am holding back on all the obvious jokes here, I am sure you will make up for it in the comments). If you are shooting a close by object, 6 inch done slowly can be quite a big camera move. This is true even if you are shooting something that is further away, but have an element in the foreground.
