O-Focus DM Overview
The O’Connor O-Focus Dual Mini is a low profile, double sided follow focus with a direct drive gear mechanism optimized for use with still photo lenses. Mating the gear to the lens is accomplished via a sliding dovetail which supports the main bridge. The gear ratio is 1:.75; meaning that for every 360 degrees of rotation for the handwheel the driver gear rotates 270 degrees which gives the camera assistant a longer, more exacting focus pull on short throw photography lenses being used in cine applications.

We recommend this follow focus unit for use with DSLR cameras, Sony F3, Canon C300 as well as for lightweight RED & Arri Alexa setups.
