The Manfrotto 521EX is a remote control that works with the Sony line of XDCAM EX camcorders. The remote control gives videographers greater control over the camera's zoom, as well as other functions including record/stop. The 521EX can easily attach to jib arms and tripods, as well at the 595B Fig Rig.
Control Zoom Speed
The controller is fitted with a speed dial, allowing users to either pre-select a zoom speed or change zoom speeds mid-stream.

Invertible zoom direction can be inverted (left to right or right to left).
