The OptiTron2 Electronic Follow Focus from Optitek connects with auto focus motors built into DSLR lenses. Instead of a gear/follow focus (external motor) combination, it seamlessly integrates with the lens and the camera system for accurate, repeatable, smooth, and responsive control of focus and aperture.
Default remapping of the limited focus rotation on AF lenses to nearly full rotation (320°) of the focus knob. This provides precision needed to follow focus on high-resolution 4K sensors and beyond.
Easy rotation direction switch for left and right side mounting.
Easy remapping of custom user-defined focus range to full rotation of the knob, for critical focus and macro work.
Adjustable iris scale for monitoring aperture position on the OptiTron2.
Backlit aperture and focus control for nighttime and dark environment use.
Easily and quickly adjust the tension of the focus knob to suit the individual focus puller preference.
The focus drag lever under the battery cage lets you adjust tension on the focus knob. It provides five steps from loose to tight.
The marking ring snaps on and is backlit at all times. There is an index line at the 12 o'clock position.
The iris slider has a marking strip for felt pen. The marking strip is adjustable so the scale once marked can be reused for different lenses.
