8. Illumination Scale – 5 I Lenses
8.1 Overview
5I lenses are equipped with two sets of LED’s which can controlled to illuminate
the scales in low light situations. The brightness level of one set can be altered while
the other is OFF, or both sets can be altered in unison. Manual Control of the brightness
levels is achieved using the Aperture Ring. The brightness levels can also be controlled
remotely by using the 5I Lighting Control Unit or issuing the Kjn or Kkn Commands.
