Each ring is engraved with a scale from infinity to one of five close focus values and can
be used with a wide range of lenses from wide angle to telelphoto. For more information
please refer to section “6.2.3.2.1.4. Pre-marked rings” on page 49 in this manual.

The datum line is the reference mark on the knob. It illuminates with the knob scale
illumination. Its brightness can be controlled in the “Knob brightness” menu.
5.2.2.5. Knob illumination and status LEDs
The knob scale can be illuminated individually through the “Knob brightness” menu.
The status LEDs for the knob are built into the scale illumination, which gives you direct
feedback of the status for the knob axis.
