The lens can be connected to different types of virtual control systems
via its 16-bit encoder outputs, including Canon's Digital Drive ZSD-300D
zoom demand and FPD-400D focus demand. The FDJ-P01 focus demand can also
be used via a 20-pin conversion cable to remotely control the iris by
changing the setting from the display on the drive unit. The 16-bit,
high-resolution encoders provide accurate lens data to the system to
help avoid any discrepancy between the changes made in the lens settings
and the virtual images.
