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 (2) on the rear face of the head. The control
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 (11) on the left-hand side. The whip-
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) are fitted on the left-hand side of the head.
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.

8 The camera mounting plate (6) is a sliding fit in the head, adjustable fore and aft by 50mm from its
central position and is graduated along one edge to assist in repeat camera set up. A platform lock, operated
by a rotary lever (1), is located on the right-hand side of the head for adjustment of the plate position. The
head also has a release device (13) on the left-hand side, which allows removal of the camera and mounting
plate complete. To remove the mounting plate, release the slide clamp and move the mounting plate fully
rearwards. Operate the release by depressing it in the direction of its indicator arrow and holding. With the
release depressed, the end stops which limit the mounting plate travel are disengaged, and the plate can be
slid bodily from the head. This feature is an aid to rapid camera set-up.
9 Attachment points (3) for the pan bar are located at the rear of the head, on either side of the camera
mounting platform. The pan bar (9) is fitted using a pan bar clamp, with angular adjustment available on the
mount serrations. A second pan bar may be fitted. A level bubble (4) is fitted to the rear of the pan housing.

LF Pan and Tilt Heads Operators Guide, Publication Part No. 3390-8.
Installing the head on a tripod
2 The Vision 5LF head is supplied with a 100 mm ball base and is designed for installation on a
compatible Vinten Vision tripod.
3 Adaptors are available which enable the heads to be installed on tripods or pedestals fitted with other
mountings.
4 To install the head, remove the bowl clamp assembly (7) from the head, position the head on the tripod
and refit the bowl clamp assembly from below. Level the head with the aid of the level bubble (4) and tighten
the bowl clamp.
Mounting the camera
5 Remove the slide plate (6) from the head by releasing the slide clamp (1), pressing the slide lock
release (13) and pulling the plate to the rear.
6 Attach the slide plate to the camera or camera mounting plate under the approximate centre of the
camera's weight using both fixing screws (5). Position the screws as far apart as possible.
7 Push the slide plate and camera into the track in the platform, ensuring slide release (13) snaps into
position.

Balancing the head
9 Balancing the Vision 5LF 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”.
10 The graph (Fig 2.2) illustrates the relationship between load and centre-of-gravity (C of G) height and
may be used to ascertain the suitability of the head for any given combination of camera, lens and
accessories. The shaded area of the graph corresponds to those loads/C of G heights that can be balanced
over the full tilt range. The areas to the right indicate the progressively reducing tilt range over which the head
can balance higher loads.
11 Prior to balancing the head ensure that the pan bars and any ancillary equipment have been fitted in
order to prevent upsetting the balance once it has been achieved.

12 Balance the head as follows:
12.1 Release the tilt brake (12). Turn the balance knob (2) counter-clockwise until the head falls away
from horizontal under the weight of the camera.
12.2 Release the slide clamp (1) and slide the camera backwards or forward until it balances
horizontally. Apply the slide clamp (1).
12.3 Turn the balance knob (2) clockwise until the camera does not fall away when the head is tilted
and released.
12.4 Repeat Para 12.2 and Para 12.3 until perfect balance is achieved, when the camera will remain
set at any angle from +85° to –75° without falling away or springing back. Re-apply the tilt brake (12).
Pan and tilt brakes
13 Friction brakes on each axis allow the head to be locked at any chosen position. The operating levers
for the pan brake (10) and tilt brake (12) are fitted at the left-hand side of the head.
14 To apply the brake, turn the lever fully clockwise. To release the brake, turn the lever fully counter-
clockwise.
Pan and tilt drag
15 Both the pan and tilt mechanisms incorporate the Vinten liquid friction (LF) system to ensure smooth
movement of the camera about these axes and are fitted with control knobs to adjust the drag setting.
16 The tilt drag adjustment knob (11) is on the left-hand side of the head, the pan drag knob (8) is on the
right-hand side. To increase drag, turn the knob clockwise, towards a higher graduation. To decrease drag,
turn the knob anti-clockwise, towards a lower graduation.The whip-pan facility is unaffected by the pan drag
setting.
NOTE: Maximum tilt angle is less than +85° to –75° for heavy payloads with high C of G - see
balance graph.

General
1 The Vision 5LF head requires a minimum of periodic servicing. Its rotational and drag mechanisms are
totally enclosed to prevent the ingress of dirt or foreign bodies. If the head becomes faulty reference should be
made to Section 5 of this manual, or the unit may be returned to Vinten Broadcast Limited or your local
distributor for overhaul.
Cleaning
2 During indoor use, the only cleaning required should be a regular wipe over with a lint-free cloth. Dirt
accumulated during storage may be removed using a semi-stiff brush. Particular attention should be paid to
the levelling ball and mounting face of the head and to the space between the tilting assembly and the base.
3 The Vision 5LF head is weatherproof. However, use out-of-doors under adverse conditions will require
special attention. Salt spray should be washed off with fresh water at the earliest opportunity. Sand and dirt
acts as an abrasive and should be removed using a semi-stiff brush or vacuum cleaner
Lubrication
4 The bearings in the pan and tilt head are packed with grease. Under normal operating conditions they
will only require re-greasing if there is any harshness or stiffness in movement. Refer to Section 5 to dismantle
the head for re-greasing.
5 To check the bearings, turn the balance control as far as possible counter-clockwise, turn the pan and
tilt drag controls fully counter-clockwise and release the brakes. At these settings both pan and tilt axes
should move smoothly and without perceptible drag.
NOTE: Use only detergent-based cleaners. DO NOT use solvent- or oil-based cleaners, abrasives
or wire brushes to remove accumulations of dirt, as these damage the protective surfaces.
