The VISION 250 pan & tilt head is designed to support the latest portable digital camera combinations used in Studio and Outside Broadcast production. With its unique "twin balancing mechanism" the Vision 250 can be fully adjusted to perfectly balance any camera or lens combination quickly and easily up to 72.8 lb. Incorporating a drag mechanism employing non-contacting thin film technology, which ensures consistent drag and constant performance over a temperature range from -40°F to +140°F. TF drag enables the camera operator to move the camera in a "seamless path" when moving from a critical tight lens image on a delicate slow pan movement - into a "whip-pan" action. Ensuring instant recovery to the original drag setting without the need to adjust the drag control position.
