Introduction

The Vision 250 pan and tilt head embodies an adjustable spring counterbalancing mechanism,

thin film (TF) drag assemblies for pan and tilt motions and an adjustable camera mounting plate.

The balance system is easily adjusted by a knob (2) on the rear of the head. Maximum and mini-

mum payloads that can be balanced, and tilt ranges, are depend-ent on the weight of the camera

and accessories and on the centre of gravity (C of G) height.

ThegraphshowstherangeofloadandC ofG height thatcan be maintainedin balance.Theshad-

ed area of graph corresponds to those load/C of G combinations that can be balanced over the

full tilt range. The area to the right indicate the progressively reducing tilt range with greater load

and higher

C of G.

Where a load/C of G combination falls outside of the graph it will be necessary to increase or de-

crease the weight or the C of G height - if possible - to enable the head to balance the load.

A digital display (6) indicates the setting of the balance mechanism on a scale of 00 - HI. The dis-

play is illuminated by pressing the switch (9) and extinguishes automatically approximately 15

seconds after adjustments are complete. The same switch also illuminates the level bubble (4)

and the scales of the pan and tilt drag knobs (19)(10). A sensor (5) automatically compensates for

ambient light levels and dims the display. If the ambient light level is high, the level bubble and

drag knob scales will not be lit. The battery forthe system is housed in a compartment in the base

of the head, closed by a cover (16).

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 (19)(10) to adjust the

drag setting. The whip-pan facility is unaffected by the pan drag setting. Both drag knobs are pro-

vided with scales illuminated by the switch (9).

Friction brakes on each axis allow the head to be locked at any chosen position. The operating

levers for both brakes (11)(12) are fitted on the left-hand side of the head.

A centre lock (3) allows the head to be locked in the horizontal position.

A level bubble (4), illuminated by pressing the switch (9), is fitted to the rear of the head.

Pan bar mounting points (8) are located at the rear of the head, on either side of the camera

mounting platform. A telescopic pan bar (20) 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.

Two versions of the head are available. One uses a dual 100/150 mm ball mount (17) with a bowl

clamp (18). The other has a flat base (7), with `Quickfix'®and standard four-hole fixing. Mounting

bolts, washers and a spanner are also provided.

The camera is attached to the head by means of a slide plate (14) or by using the optionalQuickfit®

adaptor. A clamp (15) is provided to hold the slide plate in position and a lock (13) prevents its

inadvertent removal from the head.

Operation

Installing the head

The Vision 250 head is supplied with a dual 100/150 mm ball base and is designed for installation

on a compatible Vinten Vision tripod.

The head is also available with a flat base, with `Quickfix' and standard four-hole fixing.

Adaptors are available which enable the heads to be installed on tripods or pedestals fitted with

other mountings. These are listed under ‘Optional Accessories’.

To install a head with a ball mount, remove the bowl clamp assembly (18) from the head, position

the head on the tripod and refit the bowl clamp assembly from below. Level the head with the aid

ofthelevelbubble(4)andtightenthebowlclamp.Thelevelbubblemaybeilluminatedby pressing

the switch (9).The light will extinguish after 15 seconds.

The flat based head may be installed on a tripod or pedestal using the four mounting bolts and

washers provided or by using a `Quickfix' adaptor.

Mounting the camera

Remove the slide plate (14) from the head by releasing the slide plate clamp (15), pressing the

slide lock release (13) and pulling the plate to the rear.

Attach the slide plate to the camera or camera mounting plate under the approximate centre of

the camera's weight using both camera mounting screws (1). Position the screws as far apart as

possible.

Set the platform level and engage the centre lock (3).

Push the slide plate and camera into the platform from the rear, ensuring slide lock release (13)

snaps into position.

NOTE: If the ambient light level is high, the level bubble will not be lit.

Mounting the camera (optional Quickfit adaptor)

If not already attached, secure the Quickfit adaptor (23) to the slide plate (14) with the two screws

provided (1).

Free the Quickfit wedge (22) from the adaptor by simultaneously pushing in the safety catch (25)

and operating the wedge release (24).

Fit the Quickfit wedge (22) to the camera with the two screws provided (21).

Set the platform level and engage the centre lock (3).

Insert the forward end of the wedge into the forward end of the adaptor. Lower the rear of the

wedge into the adaptor until an audible click indicates that the wedge is locked.
