Introduction
1 The Vision 5LF 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 +85° to -75° is available at intermediate
loadings, whilst at higher loadings the range of tilt motion is progressively reduced. 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 ENG 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 5LF pan and tilt head embodies a spring counter-balancing mechanism, lubricated friction
drag assemblies on the pan and tilt motions and a camera mounting plate.
4 The balance system is easily adjusted by a cruciform knob
compensates for differing platform loads by varying the compressive force on the counter-balance spring.
5 Both the pan and tilt mechanisms incorporate LF drag systems to ensure smooth movement of the
camera about these axes and are fitted with calibrated control knobs to adjust the drag setting. The pan drag
control (8) is mounted on the right-hand side of the head and the tilt drag
pan facility is unaffected by the pan drag setting.
6 Friction brakes on each axis allow the head to be locked at any chosen position. The operating levers
for both brakes (10)(12)
7 A 100mm ball type base is supplied as standard, with a bowl clamp (7). An adaptor is available for
conversion to a standard flat base. This adaptor permits mounting to a flat surface, either directly, via the
tapped holes in the base, or via a Vinten Quickfix adaptor. Bases are not interchangeable.
