Install the Focus Hook Screw
The camera comes with a screw stored in the bottom of the media bay, called the focus hook screw. You can install this screw in the Focus Hook Mounting point (along the sensor plane), and then pull focus from that location. You can either attach measuring tape directly to the screw, or you can install a hook to the screw, and attach the measuring tape to the hook.
To install the focus hook screw, follow the instructions below:
REQUIRED TOOL(S): Slotted screwdriver
NOTE: Cameras manufactured before December 2017 include a set screw installed in the Focus Hook Mounting Point. If your camera has this screw, remove the screw with a 1.5 mm hex key before installing the focus hook screw.
