85 to 210mm ZOOM LENSE - K4

85-210mm Zoom Lens [FG6200]
for use with K range Projectors

An amazingly versatile and well made Zoom lens for the K4 projector

All OPTI Kinetics projectors are supplied with an 85mm focal length lens as standard  The 85-210mm lens, FG6200, is available as an alternative zoom lens for the K4 projector. Variable from 85mm to a very narrow 210mm, making it suitable for projecting in very large venues.

If you've seen dazzling oil and pattern projections at a Pink Floyd tribute concert at the Albert Hall in London, you've probably seen one of these in use!

Can also be used with the GoBo range of projectors using the Lens Mount LA528037 (GS6100) and the Lens Support LA528038 (GS6101).

Lens Angles

The focal length of a lens determines how wide an angle the image is projected. In simple terms the larger the number of the focal length of the lens the narrower the beam. The lower the number the wider the angle. This angle is called the 'inclusive' angle. The 'inclusive angle' of each lens can be plotted on design drawings to determine the projected image size.
