This is just a rush Video Test to show the Okii USB Follow Focus Controller when mounted on a rig and manually changing focus using the controller's knob.

This is the ORIGINAL video clip saved by the camera. It is not edited in any way. Due to very slow internet speed connection a longer video was not possible to be uploaded yet.

Please don't judge the focus puller abilities :) Especially since he was watching the 3" camera LCD screen and not an external monitor (a huge advantage, completely possible while using this device).

Also keep in mind that the camera has Full Frame sensor (very shallow depth of field) and aperture was set to f/4 on focal length of 50mm.
