camera.

CEI Retrofit of Arri SR-3 Elbow

With the CEI retrofit kit, the following common situations
experienced with the Arri elbow can be avoided:
• Standard 16 video images are typically smaller than desired.
• Super 16 images are too large to fit on typical monitors.
• Physical mount is difficult to center and secure.
The kit replaces the back end of the Arri elbow. It uses a
moveable optic for size adjustment in Super 16, and allows
for the addition of spacers for size reduction in both Super
16 and standard 16.
To install the CEI retrofit kit,
1. Loosen the three set screws used for centering. These are
located just inside the large black ring.
2. Unthread (turn CCW) the large black ring of the Arri elbow.
Collect any shims, the C-mount rims and the crescent-shaped
spring wire.
3. Remove the four Phillips screws and dismount the black
metal flange from the gray painted body.
4. Mount the CEI retrofit with the four Phillips screws, with the
clamp screw outboard. Tighten all four screws, then loosen
the two outer ones (the ones with nonmetallic washers) 1/4
to 1/3 of a turn.
