focus movements and aperture control.
Focus tab
Note: All focus positions are relative. The driver will return 5000 after power up (USB connection) regardless
of the real focus position. Absolute positioning doesn't make much sense, because there is no normal
position feedback (encoder, etc). The user can focus manually, and the controller (and even the Canon
camera) will not know anything about it.
If you want to change the aperture value, call the driver setup dialog box (click on
Setup
menu item),
change aperture value settings and click OK. You don't need to reconnect the driver. Changes will take
effect immediately.
