Short Test (not a professional video!) to show a simple Rack Focus operation using the Okii USB Follow Focus controller.
This is the Original untouched file, recorded by the camera and uploaded here. Not edited nor converted at all. (original file available for download)
PLEASE CHECK FULL DETAILS BELOW.
Focus point #1: David
Focus point #2: Chairs
To give an idea of distances:
Subject "David" was at 0.8m (2.6ft) from the camera and subject "Chairs" at 5m (16.4ft) from the camera
After adjusting the controller and saving the focus points, with the focus set on the subject "Chairs" (Focus point #2), the Rack Focus operation was as simple as pressing button Focus Point #1.
SETUP: Canon EOS 5D Mark II + Canon EF 50mm 1.4 USM
VIDEO CAPTURING SETTINGS:
24p, 1/50, f/2, ISO 800, WB: 5300K
Neutral, Sharpness: 0 (lowest), Contrast: -4 (lowest), Saturation: 0 (middle), Color tone: 0 (middle)
Sound: Camera Built-in Mic.
Settings: Manual gain (25%) (* see below)
Okii USB FF CONTROLLER SETTINGS:
"Small" Steps, 15 commands per second.
With this lens (Canon 50mm 1.4 USM) it is possible to reach about 19-20 commands per second with the "Small" step, which makes it even faster than on this test for such a small focus increment.
(*) SOUND NOTES: The recorded sound may distract from the actual video result. It does not reflect the real sound level made by the lens during the process. The sound was recorded only to make note that the motor is running BUT in the REAL field it is barely noticeable, even with this lens that is not the quietest Canon USM lens.
OF COURSE, no sound would be heard nor recorded at all if an external microphone is properly placed and used.
** STRONGLY RECOMMENDED **
Turn sound OFF while watching the video test, to avoid confusion or distraction by the motor of the lens.
