Top view filter disc
Turn the disc clockwise or counter clockwise to select the required additional filter material, the disc
will snap-lock once in the correct position. The filter material is written on top of the disc (for example
see also print screen above) and at the bottom of the disc, the composition of the material is
configured on request and can vary. Also, each position has an indication (from 1 up to 4 lines) at the
perimeter of the disc. Position 1 (indicated as “0” on top and bottom of the disc) is always the no-filter
position, the other three positions contain filters.
WARNING:
Choose the filter material carefully, selecting the wrong filter could result in an
unexpected image quality. Always verify the selected filter position.
