Oconnor O-Focus DM Photo Lens Pro Kit

O-Focus Dual Mini
Designed to meet the exacting needs of professional camera operators and assistants, the OConnor O-Focus Dual Mini is a
compact, double-sided direct drive follow focus unit optimized for both still and cine-style camera lenses. The precision gear drive of the main bridge is designed with a gear ratio of 1:0.75 so that 360 degrees of input (rotation of the handwheel) results in 270 degrees of output (rotation of the drive gear).

Two versions of the O-Focus DM, the Photo Set and the Cine Set, utilize different handwheels to apply a unique transmission output in order to optimize rotation for the relevant lens type.


O-Focus DM Photo Set
The Photo Set utilizes a new Hard Stop Handwheel, which has a transmission ratio of 1:1 (input:output). When coupled with the O-Focus Bridge, it yields a follow focus industry first; a 1:0.75 transmission ratio. This translates to longer, more exacting focus pulls when using limited barrel rotation still lenses for digital cinematography, and allows more precise lens control than has previously been available for these camera configurations.

A small ratio change can make a big ‘feel’ difference! The hard stops enable the operator to set minimum and maximum focus points for lenses with unlimited rotation and to carry out hard focus stop pulls. To allow the focus-puller to react to unexpected movements, the unique single-hand-operated hard stop on/off switch, allows for instantaneous disengagement of the end stops for critical adjustments even during the shot.

O-Focus DM Main Features
The modular design of the O-Focus DM enables operators who want to transition between Photo and Cine lenses to optimize the transmission ratio to suit simply by swapping out the handwheel(s) – no tools required. Both versions of the O-Focus DM feature extremely low profiles, which allow use with large diameter lenses. The sliding dovetail design provides adjustment for various lens sizes, even those with very large lens barrel diameters. Additionally, tapered flank couplings (pioneered with the
OConnor CFF-1) eliminate play between the handwheel and bridge connection.

The O-Focus DM integrates seamlessly with existing follow focus accessories including whips, cranks and gears. It also shares many of the OConnor CFF-1 accessories, such as the Studio Handwheel and Marking Discs, Handwheel Extension and Studio 15/19mm Bridge.

The new Toothless Friction Driver, for the use of still lenses, eliminates much of the need for additional toothed gear rings.
