Shooting tips:
Please plan and decide which magnification you wish to use before setting up the camera housing,
as this focus gear will only allow a fine adjustment of the focus distance but not the magnification. Once
the camera and lens have been set up, it is recommended to extend the lens all the way until it touches
the front glass of the port. Then retract the lens for about 2~3mm to allow fine focus adjustments.
**For details of working distance on different magnification scales, please refer to the lens manual.
