Optic Silent
For a complete and working IVS, either the optic silent or
the optic acacemy has to be installed inside the CCD optic
module. They can be easily exchanged.
The optic silent forms an image on the CCD chip which is
based on the 35 mm silent format with a picture width of
24 mm. An additional area will surround the actual image.
This is to check for important objects outside the image area.
The lenses are especially designed and built for the use with
the ARRIFLEX 435 to achieve the best possible image quality.
Especially the aperture of 1 : 1.4 is important for the use
as video assist lenses because only a small portion of the
light that goes through the camera lens reaches the video
chip. Therefore the lenses are not designed as zoom lenses
because it would be impossible to get the same image
quality and speed.
All silent optics are marked with an S in the serial number,
e.g. S0040.
There are no different lenses for PAL and NTSC.
Optic Academy
For a complete and working IVS, either the optic silent or
the optic acacemy has to be installed inside the CCD optic
module. They can be easily exchanged.
The optic academy forms an image on the CCD chip which
is based on the 35 mm academy format with a picture width
of 22 mm. An additional area will surround the actual image.
This is to check for important objects outside the image area.
The lenses are especially designed and built for the use with
the ARRIFLEX 435 to achieve the best possible image quality.
Especially the aperture of 1 : 1.4 is important for the use
as video assist lenses because only a small portion of the
light that goes through the camera lens reaches the video
chip. Therefore the lenses are not designed as zoom
lenses because it would be impossible to get the same
image quality and speed.
All academy optics are marked with an N in the serial number,
e.g. N0040.
There are no different lenses for PAL and NTSC.
