250 Operators Guide, Publication Part No. 3525-8. Installing the head on a tripod The Vision 250 head is supplied with a dual 100/150 mm ball base and is designed for installation on a compatible Vinten Vision tripod. The head is also available with a flat base, with ‘ Quickfix’ and standard four-hole fixing.

Position the screws as far apart as possible. Set the platform level and engage the centre lock (3).
View Balancing the head Balancing the Vision 250 head achieves two objectives. Firstly, when a head is correctly balanced the operator will need a minimum amount of even effort to move the head. Secondly, once balanced, the head and its payload can be set to any tilt position and the head will maintain this position with “hands off”.
Pan and tilt drag Both the pan and tilt mechanisms incorporate the Vinten thin film (TF) system to ensure smooth movement of the camera about these axes and are fitted with control knobs to adjust the drag setting.
