Introduction

The Vinten

Vision

counterbalancing of different camera/lens combinations. Compensation for any camera/lens combination

within the load capacity range of the head is easily accomplished via a control mounted on the rear face of the

head, which enables the head to be maintained in perfect balance, with no change of feel, at any tilt angle up

to 90° each side of horizontal. Centre of gravity heights from 75 mm (3 in.) to 250 mm (10 in.) above a camera

mounting platform can be accommodated for a camera mass in the range of 6 kg to 45 kg. The load capacity

can be increased beyond this but the range of tilt within which balance is maintained is then limited. The

balance graph

(Fig

2.1) shows the relationship between centre of gravity height, camera mass, and tilt range

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.

The Vision 30 head incorporates an improved version of the Vinten lubricated friction (L.F) system. The

LF system allows the amount of drag for both the tilt and pan movements to be varied over a wide range to

suit the operators preference and permits "whip-pan" movements to be executed, even at high drag settings.

Both pan and tilt movements are provided with a friction lock and a manually operated positive lock is

provided at the platform horizontal position.

Description

The camera mounting platform of the pan and tilt head is pivoted on a body which is itself rotatable

about a fixed base.
