With a maximum shutter opening of 200° and a wide range of ultra wide aperture lenses ranging from T1.0 and T1.3 (Spherical) and T1.1 and T1.4 (Anamorphic) PANAFLEX cameras are the most ‘light efficient’ cameras available. At T1.0 and rating the film at El 500 less that 1 foot candle of light is necessary to give full exposure.
The 200° shutter passes 1/6 stop more light than a 175 – 180° shutter and only requires to be closed down to 100° to reduce the exposure by one full stop and to 50° to reduce one stop again. The minimum shutter opening on the PANAFLEX is 50°.
In addition to transmitting more light, the PANAFLEX 200° shutter opening reduces the possibility of image strobe during fast pan movements
Note: The shutter angle of the LIGHTWEIGHT PANAFLEX is 180° and is not adjustable.
Sharper and Steadier Images
PANAFLEX cameras have a focal plane shutter which moves across the shortest side of the frame and in the opposite direction to the travel of the film. This adds very considerably to the camera’s light capping efficiency. Very precise shutter timing ensures that all light is completely cut off before the film begins to move and remains so until it has come to a stop and has been held securely in position by the registration pins. Unlike many other cameras there is absolutely no movement of the film while even the smallest part of the frame is uncovered, even at high speed.
Another important point is that PANAFLEX registration pins are full fitting and no compromise is made to quiet the camera. Furthermore, the pins are positioned on both sides of the film and engage in the perforations immediately below the frame line, the same as on all optical printers.
You can safely use any PANAFLEX camera to shoot plates for multi–exposure SFX scenes.
