The C-pan arm is a very unique camera guide contraption that mechanically can move a camera in a variety of different paths; straight pan, outward curve, inward curve, horizontally, vertically or at a sloped angle or even forward or backward moves.
The camera is always set to move with whatever move the arm makes i.e.:
if the arm moves in an outward shaped curve, then the camera will stay directed towards the centre of the curve and if the arms are set for a smaller radius curve, then the camera adjusts accordingly to stay pointed at the centre.
Through positioning its arms at different angles to each other, the C-pan arm can be set to move in a virtually infinite number of curves.
When making a straight pan, the arm functions as a traditional straight-track dolly slider, but without the tracks, where it can pan in a range of 3 1/2 times its folded length (which is approx. 55 cm).
The C-pan arm comes with dumbbells which can be used to counter weigh vertical movements and/or to smoothen and stabilise horizontal moves.
