Operating Instructions VZ-FC-U (Universal Focus Control)
This apparatus is designed for precise focus control, so careful setup and basic maintenance of the unit are essential.
Although it is simple to connect and use, there are a few extremely important rules to follow:
* FIRST: NEVER BEND THE DRIVE CABLE PAST A GENTLE ARC!! THIS IS A PRECISION-WOUND CABLE AND IT COULD BE IRREPARABLY
DAMAGED BY BENDING IT TOO FAR. LIKEWISE, DO NOT TWIST THE CABLE OR STORE IT IN A BENT POSITION.
* SECOND: WHEN CONNECTING AND SETTING UP THE UNIT, NEVER ATTEMPT TO FORCE THE MOVING PARTS. IF THEY AREN’T MOVING
SMOOTHLY, SOMETHING ISN’T CONNECTED PROPERLY. DAMAGE TO THE FOCUS CONTROL AND/OR LENS ASSEMBLY MAY OCCUR
THROUGH INAPPROPRIATE FORCE!
The FCU consists of five basic parts:
1. Remove the screw on the lens gear adapter (A) and place it around the focus ring on the camera, then replace and tighten
the screw until snug (B). Be sure the lens gear adapter is centered all the way around the camera’s focus ring (C).
2. Attach the mattebox rods and make sure they are lined up exactly parallel with the camera’s centerline (Note: The
universal bracket comes with a step-down ring for use with 15mm rods. Remove this adapter if you have 19mm rods (D)).
Now slide the bracket with gearbox (E) onto your mattebox rods and center the brass gear vertically and horizontally in
relation to the lens gear adapter (F). You may have to adjust the angle/length of the bracket by loosening the ratchet bolts (G)
(called ‘ratchet’ because the handle can be repositioned w/o tightening or loosening by pulling out on the handle, thereby
disengaging the clutch, and rotating it). Engage the brass gear to the lens gear adapter before locking everything down.
3. Affix the focus control handle to your tripod pan handle using the adjustable clamp. Once the
clamp is firmly tightened, you can adjust the orientation of the focus control handle by loosening
the screw at the locking swivel joint.
