edelkrone, the Turkish DSLR-rig manufacturer, has come up with a very interesting slider concept. A slider that lets your camera travel longer than the slider actually is in length.
edelkrone’s new funky invention isn’t cheap at $499, but the mechanism is an intriguing idea. When used on a tripod the slider can travel 1.7 inch (52cm) even though it’s only 1.3 inch (39cm) in length.
The way this works is that the slider base has a second slider sled that works in conjunction with the camera plate like a pulley tackle.
