Canon® EF Lens Controller

(Product ID: Controller: LC-2, Adapters: LC-2A-C, LC-2A-M42, LC-2A-T, LC-2A-T18, LC-2A-M58-75)lc-2 connected

The ISSI Canon® EF lens controller is designed to operate Canon® EF, EF-S and L series IS auto focus lenses as well as Sigma® and Tamron® EF lenses.  The lens controller makes it possible to operate these lenses on non-Canon® cameras.  Its Ethernet connection makes communication simple and also allows it to be operated over long distances or via a network connection.   The LC-2 control can also be written into existing software for both Windows and Linux via API commands.


  • Remotely control Canon®, Sigma® and Tamron® EF/EF-S auto focus (AF) lenses on any camera
  • Accurate and repeatable control of Focus, and Aperture (Iris)
  • Image stabilization control (IS for Canon®, OS for Sigma® and VC for Tamron®) 
  • Auto-detection of attached lens and F-number stops with included lens adapter
  • 10/100Mbps Ethernet interface
  • Multiple controllers can be connected and simultaneously controlled over a network
  • Easy to use software interface and TCP/IP API commands for Windows/Linux/MacOS
  • Unlimited programmable preset capability to easily store and recall saved positions on the lens
  • M42x1-mount (LC-2A-M42), c-mount (LC-2A-C), T-mount (LC-2A-T) and M58-mount (LC-2A-M58-75) lens adapters are available with the LC-2 


The lens control system consists of the lens control box (LC-2) and a lens adapter to connect the EF lens to a specific camera connection.

Pairing a Lens Adapter to a Camera

In order for infinity focus with EF lenses, the flange focal distance of 44.0 mm must be maintained.  Flange focal distance is the distance from the lens mounting flange to the sensor image plane.  Drawings below in the CAD Drawings section show the thickness of each adapter ("B").  Camera datasheets will specify "A" in their mechanical drawings.
