Fig. 55: OVF top view, with mounting points marked
To extend the viewfinder arm:
1. Loosen the straight-structured ring next to the FIX engraving counter-clockwise
(contrary to the arrow).
2. Adjust the horizontal position.
3. Tighten the ring clockwise (with the arrow direction).
To adjust barrel friction:
► Move the dot-structured ring according to the engravings LOOSE and FRICTION
to loosen or tighten the friction of the OVF barrel.
Contrast Filter
To achieve a temporary subjective reduction of viewfinder contrast range, a contrast
filter (density 0.6) can be pivoted into the optical beam path.
1. Use the lever next to the level bubble to pivot the contrast filter into the optical
path.
2. Releasing the lever pivots the contrast filter back out of the optical path.
Ground glasses
The image created by the lens is projected to the ground glass, from where it is picked
up by the optical viewfinder.
Ground glasses contain frame and format markings to show the recorded image area
and the area of interest. The sensor aperture of the ALEXA SXT Studio is different
from the camera aperture of ANSI and DIN Super35 formats. Therefore, Super35
ground glasses of the ARRICAM system do not provide exact frame markings in the
ALEXA SXT Studio viewfinder image. For exact framing, use only ground glasses
made specifically for the ALEXA SXT Studio.
To exchange a ground glass:
1. Press the VIEW button so that the sensor is protected by the mirror shutter.
2. Turn off the camera and disconnect it from power supply.
3. Remove the lens or protective cap.
