(until it reaches its stop), and then tighten back the screws. To set
the viewfinder to STANDARD35, shift the handle toward the DIS-
PLAY side.
6.2.3 Selecting a Viewing Screen
There is a wide choice of Standard35 viewing screens and four
Super35 ones to the 1.78, 1.85, 2.35 and Scope aspect ratios. To
install a new one, please read chapter II, viewing screen section.
WARNING: when shooting Standard35 DO NOT leave the camera
in the Super35 alignment, thinking that framing with a Standard35
screen will define the picture to be extracted from the wider
Super35 recorded image. As far as video transfer is concerned, this
practice could be acceptable because the telecine ‘pan-scan’ function
allows to reframe the picture for the lack of 1.27mm optical center
shift, but when it comes to release prints the image would be
1.27mm truncated at the projector gate level: on the left of the
screen some objects would disappear and on the right some unex-
pected ones would show up (6% of the image width -1.27/22mm-
each side).
6.2.4 Adjusting the Video Tap
The beamsplitter which diverts the viewing screen image to the
video-assist CCD target is mounted on the taking lens mount tita-
nium seat, it is thus not necessary to realign its optical axis, but the
focus must to be readjusted. Please read Chapter II, video-assist sec-
tion.
