Introduction
1
The Vision 8 (Black) 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.

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.
Description
3
The Vision 8 pan and tilt head embodies a spring counterbalance mechanism, LF drag assemblies,
brakes on the pan and tilt mechanisms and a camera mounting plate.
4
The balance system is easily adjusted by a knob
on the rear of the head. Maximum and minimum
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
to adjust the drag
setting. The whip-pan facility is unaffected by the pan drag setting. Both drag knobs are provided with scales
graduated from 0 to 9.
6
Friction brakes on each axis allow the head to be locked at any chosen position. The operating knobs
are fitted at the left-hand side of the head.
7
are located at the rear of the head, on either side of the camera mounting
platform. A fixed pan bar
is supplied and is attached using a pan bar clamp, with angular adjustment
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
or by using the optional Quickfit
adaptor. A clamp
is provided to hold the slide plate in position and a lock
prevents its inadvertent
removal from the head.
