Choose a compatible driver gear for your lens (see page 10).
mounting the handwheel The O-Focus DM incorporates a Minimal Backlash Mechanism to guarantee precision focus pull with less play and higher accuracy. Note that the assembly instructions apply to both types of handwheel. 1 Push-fit the handwheel firmly onto the main bridge. The handwheel must be fully engaged for the backlashreducing mechanism to be effective. 2 Turn the lock lever clockwise to secure the handwheel on the main bridge.
mounting onto the camera rods Mounting the O-Focus DM to the lens requires the assembly to be adjusted in two steps: first assemble and mount the O-Focus on the camera rods, then adjust the main bridge, until the driver gear engages with the lens focus drive. For more information about the focal length and diameter of a wide range of camera lenses visit OConnor Labs online at the OConnor website (OConnor > Labs > ‘Lens Diameters’).
mounting the O-Focus to the lens Depending on the setup, the LWS rod bridge can also be replaced with a studio bridge to accommodate heavy-duty 15 mm or 19 mm studio camera rods (see page 10). For more information about different types of camera rods visit OConnor Labs online at the OConnor website (see OConnor > Labs > ‘Rod Standards Explained’). 3 Turn the lock lever clockwise to secure the main bridge in position. Ensure the bridge is firmly locked to avoid backlash.
