Movement: Pilot pin registration ensures optimum image steadiness. Entire movement may be removed for servicing.
Aperture Plate: Removable for checking and cleaning. Normal 16mm aperture plate is standard, Super 16 is available.
Shutter: Focal-plane shutter with infinitely variable opening and adjustable in-shot. Maximum opening 200°, minimum 50° with adjustable maximum and minimum opening stops. A digital display allows adjustments in '/io° increments. Micrometer adjustment allows critical synchronization with computers, TV monitors and HMI lighting at unusual frame-rates. Manual and electronic remote-control units available.
Reflex System: Reflex rotating mirror is standard and is independent of the light shutter system. Interchangeable semi-silvered fixed reflex mirror for flicker-free viewing is optional.
Behind-the-lens Filtering: Provision for a behind-the-lens filter gel.
Optical Viewfinder System: High magnification optical system. The viewfinder tube is orientable and gives a constantly upright image through 360°. A short viewfinder tube is provided for hand-holding operation and a normal length for tripod mounted use. Viewfinder tubes may be
swung out to suit left- or right-eye viewing. System incorporates an optical magnifier for critical focusing and picture composition, a contrast viewing filter and a light-proof shutter. Wide-range ocular adjustment with marker bezel to note individual settings. A built-in "Panaclear" eyepiece heater ensures mist-free viewing. Adjustable leveler link arm supplied with every Panahead to keep eyepiece position constant while tilting the camera up or down. An eyepiece diopter to suit the operator's own eyesight can be provided on request.
Ground Glasses: "Panaglow" illuminated reticle system with brightness control is standard. Ground glasses with finer or coarser texture available on request.
Lens Mounting System: Panavision positive clamp lens mount for maintaining critical flange focal depth setting. All lenses are pinned to ensure proper rotational orientation.
Lenses: Specially designed and manufactured Panavision-16 lenses to suit the 16mm image format. All lenses checked and calibrated by MTF. Panavision 16mm lenses are all color-matched and range from a distortion-
free 8mm to 135mm (lists are available). A wide range of Panavision-engineered long-focus and zoom lenses by other manufacturers are also available. All lenses have widely spaced lens focus calibrations and exceptionally low image veiling glare. Physically long lenses are supplied with adequate-length iris rods for matte box and filter support.
Lens Control: A lightweight focus control which can be used from either side of the camera is standard; an interchangeable "Studio" focus control unit is optional, as are electronic remote focus and aperture controls. Zoom lenses are supplied with an electronic zoom control unit as standard.
Matte Boxes: A standard matte box incorporating a sunshade, provision for two 4 X 5.650 filters which can be individually slid up and down. Special matte boxes incorporating more filter stages, with provision for sliding (motorized if required), rotating and tilting — and to take 6.6" square filters — are optional. Panavision can also supply special sliding diffusers, diopters and all manner of image control filters, etc., to use in their matte boxes.
Camera motor: A 24-volt motor is used to run the camera at any speed from 4-36 fps, is crystal-controlled at all speeds and may be adjusted in Vio fps increments. Special sync boxes are available to synchronize the camera with a main power supply, with computers, with video sig-
