EF Zoom Lens Controller

(Product ID: LC-PZA2)

The EF Zoom Lens Controller is a complete EF lens control system designed to operate a limited number of EF zoom lenses, giving full control of the zoom, focus and aperture of a lens.  The controller is designed to operate select Canon® EF and L series IS auto focus lenses as well as select Sigma® EF lenses.  Commands for the controller can be written into existing software for both Windows and Linux via API commands.  The controller pairs with a LC-2A lens adapter to connect to a variety of camera mounts.    The device is operated via a graphical user interface and allows for preset positions of the lens to be saved and then recalled at any time.  It can also be integrated into existing software via TCP/IP API commands in Windows and Linux operating systems.
