Introduction
1 The Vision 100 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 thin-film (TF) 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 100 pan and tilt head embodies a spring counterbalance mechanism, TF drag assemblies,
brakes on the pan and tilt mechanisms and a camera mounting plate.
4 The balance system is easily adjusted by a knob (16) 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. A digital display (14) indicates the setting of the balance
mechanism on a scale of 00 - HI. The display is illuminated by pressing the switch (13) and extinguishes
automatically approximately 15 seconds after adjustments are complete. The same switch also illuminates the
level bubble (15) and the scales of the pan and tilt drag knobs (12)(6). The digital display and illumination
systems automatically compensate for ambient light levels. The battery for the system is housed in a
compartment in the right-hand side of the mechanism housing, closed by a cap (11).
5 Both the pan and tilt mechanisms incorporate the Vinten thin film (TF) system to ensure smooth
movement of the camera about these axes and are fitted with control knobs (12)(6) to adjust the drag setting.
The whip-pan facility is unaffected by the pan drag setting. Both drag knobs are provided with scales
illuminated by the switch (13).
6 Friction brakes on each axis allow the head to be locked at any chosen position. The operating levers
for both brakes (5)(7) 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 telescopic pan bar (1) 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 (9) or by using the optional Quickfit
adaptor. A clamp (10) is provided to hold the slide plate in position and a lock (8) prevents its inadvertent
removal from the head.
9 A ball base and clamp (4) for mounting on a 100 mm bowl is provided. Adaptors are available which
permit installation on other mounts.

10 The optional VHS adaptor (22) consists of a VHS pin and a 1/4 in. BSW camera mounting screw
connected by a plastic link.
11 To mount the camera using the VHS adaptor, proceed as follows (Fig 2.2):
11.1 Remove the slide plate (9) from the head by releasing the slide plate clamp (10), pressing the
slide lock release (8) and pulling the plate out to the rear.
11.2 Remove the two 3/8 in. BSW camera mounting screws (2) from the slide plate.
11.3 Position the VHS (22) adaptor in the longer slot in the slide plate, with the pin facing forwards.
Screw the pin securely into the slide plate.
11.4 Secure the slide plate to the camera with the 1/4 in. BSW camera mounting screw, ensuring the
pin engages in the hole in the camera.
11.5 Set the platform level and apply both the pan and tilt brakes (5, 7).
11.6 Push the slide plate and camera into the track in the platform, ensuring the slide lock release (8)
snaps into position.

Balancing the head
12 Balancing the Vision 100 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”.
13 The graph (Fig 2.3) 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.
14 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.
14.1 Release the tilt brake (7). Turn the balance knob (16) counter-clockwise until the head falls away
from horizontal under the weight of the camera.
14.2 Release the slide clamp (10) and slide the camera backwards or forward until it balances
horizontally. Apply the slide clamp (10).

14.3 Turn the balance knob (16) clockwise until the camera does not fall away when the head is tilted
and released.
15 Repeat Para 14.2 and Para 14.3 until perfect balance is achieved, when the camera will remain set at
any angle from +90° to –90° without falling away or springing back. Re-apply the tilt brake (7).
16 Press the switch (13) and make a note of the digital display (14). This will facilitate rebalancing this
particular payload.
Pan and tilt brakes
17 Friction brakes on each axis allow the head to be locked at any chosen position. The operating levers
for the pan brake (5) and tilt brake (7) are fitted at the left-hand side of the head.
18 To apply the brake, turn the lever fully clockwise. To release the brake, turn the lever fully counter-
clockwise.
Pan and tilt drag
19 Both the pan and tilt mechanisms incorporate the Vinten thin-film (TF) system to ensure smooth
movement of the camera about these axes. and are fitted with control knobs to adjust the drag setting.
20 Both drag knobs are provided with illuminated scales, graduated from 0 to 9. To illuminate the scales,
press the switch (13). The lamps will extinguish after 15 seconds.
21 The tilt drag adjustment knob (6) is on the left-hand side of the head, the pan drag knob (12) is on the
right -hand side. The whip-pan facility is unaffected by the pan drag setting.
22 To increase drag, turn the knob clockwise, towards a higher graduation. To decrease drag, turn the
knob anti-clockwise, towards a lower graduation.
NOTE: If the digital balance setting of the particular payload is known, press the switch (13) and
turn the balance knob until the digital display (14) shows that setting.
NOTE: Maximum tilt angle is less than 90° for heavy payloads with high C of G - see balance
graph.
