Choose a clamp ring to suit your camera lens.
Turn the knurled screw anti-clockwise to widen the
rear clamping interface. The clamp ring uses a
collet design making it easier to compress.
Squeeze the ring adapter slightly, then carefully fit
it into the clamping interface.
Fit the clamp ring over the camera lens. Turn the
knurled screw clockwise to secure the clamp ring to
the lens ensuring that it is firmly attached and that
the mattebox cannot slip.
Use the clamp ring to mount the O-Box directly onto the camera lens.
This type of setup is used when carrying the camera on the shoulder
or when mounting it without camera rods. Four standard-size clamp
rings are available (see page 8).
