O`Connor C1242-0001 O-Focus DM Photo Lens Pro Kit

Designed to meet the exacting needs of professional camera operators and assistants, the OConnor O-Focus Dual Mini Photo Lens Pro Kit (Part No. C1242-0001) features 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.

The Photo Set utilizes a 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 canmake 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-handoperated hard stop on/off switch, allows for instantaneous disengagement of the end stops for critical adjustments even during the shot.
