Introduction
1 The Vision 6 pan and tilt head is part of a range designed for broadcast professional, corporate and
educational use. It is constructed largely in aluminium and magnesium alloys to produce a robust, lightweight
unit. The unique counterbalance system enables a wide variety of camera/lens combinations to be maintained
in perfect balance over the range of tilt movements. A maximum tilt angle of 90° is available at intermediate
loadings, whilst at higher loadings the range of tilt motion is progressively reduced to 40°. A graph is provided
in Section 2 which illustrates the relationship between load and centre-of-gravity (C of G) and may be used to
ascertain the suitability of the head for any given combination of camera, lens and accessories.
2 Drag is provided by the Vinten lubricated friction (LF) system which allows wide variation of the drag
setting on both pan and tilt axes to suit operator preference, and permits "whip" movements to be executed,
irrespective of drag setting. Pan and tilt axes are each provided with a brake.

assemblies, brakes on the pan and tilt mechanisms and a camera mounting plate.
4 The balance system is easily adjusted by a knob
payloads that can be balanced, and tilt ranges, are dependent on the weight of the camera and accessories
and on the centre-of-gravity (C of G) height. The control compensates for differing platform loads by varying
the compressive force on the counterbalance spring.
5 Both the pan and tilt mechanisms incorporate the Vinten lubricated friction (LF) system to ensure
smooth movement of the camera about these axes and are fitted with control knobs
setting. The whip-pan facility is unaffected by the pan drag setting. Both drag knobs are provided with scales
graduated from 0 to 9.

available on the mount serrations. A second pan bar may be fitted.
8 The camera is attached to the head by means of a slide plate (12), using the 3/8 in. screws
adaptor, or by using the optional Quickfit adaptor. A clamp
