Congratulations on the purchase of your new OConnor O-Focus DM!

We want you to get the most from your new O-Focus Dual Mini, and therefore encourage you to read this user guide to familiarize yourself with its many features, some of which may be new to you. It also covers essential information about safety and product care.

Features and benefits of your new O-Focus DM

The O-Focus Dual Mini, the latest addition to the range of genuine accessories from OConnor, offers a host of inspired and productive features:

• the double-sided follow focus is constructed of lightweight, durable black anodized aluminum
• the low-profile design with a direct-drive gear is ideal for large barrel diameter lenses
- optimized focus throw: the O-Focus DM Photo offers a longer, more exacting focus pull for short throw lenses and the O-Focus DM Cine offers a shorter, more exacting focus pull for cine lenses
- multi-functional, modular design: the bridge features a sliding dovetail design and accommodates an LWS rod bridge (included) or, optionally, a heavy-duty bridge for 15/19 mm studio setups, as well as interchangeable gears, mixed or matched handwheels, and a handwheel extension

Special features

The O-Focus DM is the first compact cine-specific unit. The O-Focus DM Photo has been optimized for use with still photo lenses in cine setups.

The highly adaptable O-Focus DM Cine has been designed for precision movement control of higher sustained torque loads. The eccentric design means it can be adjusted for optimal 'line of sight' as well as for reach.

The O-Focus DM follow focus integrates seamlessly with standard equipment such as cranks, gears, and whips, thus protecting your investment in equipment by ensuring compatibility also in the future.

Assembly – assembling the bridge

1 Assemble the bridges. Slide the LWS rod bridge onto the main bridge. Turn the lock lever clockwise to secure the LWS bridge in position.

The position of the main bridge can be adjusted using the sliding dovetail when mounting the O-Focus DM to the lens (see page 14).

2 Mount the driver gear. Choose a compatible driver gear for your lens (see page 10). Locate the driver on the output gear at the front or back of the interlock bridge as desired. Ensure the serrations fully interlock, then tighten the hollow knurled screw.

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.

3 When mounting the assembled bridges and handwheel onto the camera rods underneath the lens: Turn the knurled screw clockwise to tighten the rod clamp, then flip down to lock the O-Focus DM securely on the rod.
NOTE: Lock levers are fitted with a spring. Should a lever obstruct the path of a camera rod, for example, adjust its position: Pull the lever off the shaft as far as possible, turn it a few degrees, then let it retract. Check the clamping is tight.

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').

1 With the 15 mm LWS rod bridge securely mounted underneath the lens, turn the lock lever counter-clockwise to release the main bridge assembly.

2 Mount the O-Focus DM to the lens focus drive. Push the main bridge towards the lens focus drive, until the serrations of the driver gear fully engage. Take care not to overtighten the gear on the lens focus drive.

3 Turn the lock lever clockwise to secure the main bridge in position. Ensure the bridge is firmly locked to avoid backlash.

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).

setting the focal distances

Set the lens focal range for the O-Focus DM Photo. Using a suitable pen mark the reference points for the maximum and minimum focal distances. Hard stops prevent lenses with infinite rotation from being turned too far. The hard stops can also be used as hard focus points for run and gun shooting.

1 Using the handwheel find the start feel

Using the handwheel find the start focal point, mark this point and set the index. Turn the handwheel and establish the end stop of the focus pull. Mark with a pen, then adjust the index stoppers.

2 Set the focal distances. Loosen the index, move the large witness marker to the end position, and tighten the screw. For the start position set the index slightly beyond the first marker. Finally, move the slider button between the stops, then push it in.

1 Mount the marking disc. Align the tongue on the handwheel with the cutout on the marking disc, then push the disc onto the handwheel until it audibly 'clicks' into place.

Set the focal distances for the O-Focus DM Cine. Using a suitable pen mark the lens focal reference points. The focus throw is optimized for cine lenses to provide a shorter, more exacting focus pull.

2 Set the initial lens focus and loosen the index to set it to the preferred eye level. Use a pen to mark the focal reference points on the marking disc, until the desired distance is marked out.

3 If preferred, set the witness mark to another focal reference point. Adjust the index as required.
The O-Focus DM is now set up and ready for use.

CAUTION: Always remove the marking disc before cleaning. Do not use solvents on the O-Focus DM. Follow the instructions supplied with the marking pen when cleaning the marking discs.

Options and extras

For larger camera packages the O-Focus DM can also be used with an optional 70 mm handwheel extension (see page 7 for details). The eye level of the eccentric CFF-1 studio handwheel can be adapted for optimal 'line of sight' and for reach.
