Introduction
1
The Vision 10LF pan and tilt head is part of a range designed for broadcast professional, corporate and
educational use. It is largely constructed in aluminium alloy 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 movements are each provided with a brake.
Description
3
The Vision 10LF pan and tilt head embodies a spring counterbalance mechanism, lubricated friction
drag assemblies and brakes on the pan and tilt mechanisms and a camera mounting plate.
4
The balance system is easily adjusted by a knob
(1)
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 LF system to ensure smooth movement of the
camera about these axes and are fitted with control knobs
(7)(11)
to adjust the drag setting. The whip-pan
facility is unaffected by the pan drag setting. Both drag knobs are provided with scales.
6
Friction brakes on each axis allow the head to be locked at any chosen position. The operating levers
for both brakes
(10)(12)
are fitted at the left-hand side of the head.
7
Pan bar mounting points
(3)
are located at the rear of the head, on either side of the camera mounting
platform. A pan bar
(6)
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
(1)
or by using the optional Quickfit
adaptor. A clamp
(5)
is provided to hold the slide plate in position and a lock
(13)
prevents its inadvertent
removal from the head.
9
A ball base and clamp
(9)
for mounting on a 100 mm bowl is provided. Adaptors are available which
permit installation on other mounts.
