* Not all lenses are capable of using focus points due to differences in mechanical design and certain characteristics of Canon's USB protocol. Please refer to the Canon USB Protocol article in the Technical section of the Okii website for more details.


Camera Compatibility:

  • Canon EOS 1D X, 1D Mark IV, 5D Mark III, 5D Mark II, 7D, 60D, 600D, 550D, and 500D.

Lens Compatibility:

  • All Canon, Sigma, and Tamron autofocus lenses are known to function.
  • Tokina lenses work, but can experience camera lock ups with the Canon 7D if the focus command rate is set faster than the lens is able to move the internal focus element.
  • Manual focus lenses will not have focus control, but other functions such as settings changes or video start/stop will work.

Note: The autofocus motor noise is audible to internal microphones on Canon cameras, especially if AGC (auto gain control) is enabled. We recommend that an external microphone be used in combination with the FC1 USB Focus Controller.

It is important that potential users understand how Canon's USB implementation affects the FC1. Certain characteristics of Canon's design make it perform quite differently than a mechanical follow focus, so it is recommended that you read the User Guide and the Canon USB Protocol article.
