I2C Serial Interface, M42x1.0, 32 Optical Thickness (mm)
The Integrated EF Lens Controller is a compact version of the EF lens controller used to operate all features of an EF zoom lens. The entire lens control system is built into the adapter housing, eliminating the need for a separate control box. The Integrated EF Lens Controller is designed with system integrators in mind to provide minimal components as well as an industrial RS-232/422/485 serial or I2C communication interface. Commands for the controller can be written into existing software for both Windows and Linux via ASCII-based commands. The controller fits a variety of camera interfaces and can also be customized to fit a specific camera body.
