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:

Ÿ the double-sided follow focus is constructed of lightweight, durable black anodized aluminum

Ÿ the low-profile design with a direct-drive gear is ideal for large barrel diameter lenses

Ÿ 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

Ÿ 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.
