Canon Knob-LC

Illunis has developed the second generation of its Canon lens controllers that supports both traditional EF/EFS lenses and newer RF/RFS lenses. Illunis has developed a unique Wi-Fi remote control for the second generation lens controllers called the KNOB-LC.

The illunis KNOB-LC remote controls aperture, focus, zoom (RF power zoom lenses only), and RF lens control ring functions. The KNOB-LC can dynamically detect lens
attachment and removal, as well as identify the lens name, focus, iris, serial number and zoom information.”
