PANAFLEX MILLENNIUM
5.7 Behind-the-lens filter
In addition to places for three or four filters in the various
Panavision matte boxes, there is also a provision on all
Millennium cameras to place a gelatin filter just in front of
the film plane.
CAUTION: Millennium filter holders are not interchangeable with
other Panaflex cameras or vice versa. They are keyed to prevent
inadvertent insertion.
Millennium cameras are supplied with a box containing
12 gelatin filter holders.
Before a shoot, the camera assistant should very carefully
mount a selection of gelatin filters into the holders as request-
ed by the cinematographer. Panavision Inc. and its distributors
worldwide can supply a gelatin filter punch for cutting filters
to shape. Be careful to keep dust, finger marks and other blem-
ishes off the surface of the filters.
The use of a gelatin filter between the lens and the film
affects the lens back focal distance by about 1
1
⁄2 thousandths
(.0015) of an inch. This is not likely to have a deleterious
effect on the focus of any lens unless it has a particularly
short focal length and/or wide aperture. If using gelatin fil-
ters, Panavision technicians can, upon request, alter the
flange focal depth setting of the camera accordingly.
To fit the gelatin filter holder into a Millennium camera,
slide back the dust/light/sound proof cover below the
viewfinder tube, insert the filter holder inwards and
upwards, close the cover slide and remind the cinematogra-
pher that a behind-the-lens filter is in place so that he can
make appropriate allowances in the exposure calculations.
NOTE: Make sure that the filter holder is fully inserted and that
the door is fully closed.
