FEET TO METER AND METER TO FEET SWAP
All of the Optimo Prime lenses have their focus scale ring engraved with both feet and metric scales. The swap of the focus scale from one
system to the other must be done with cautious in a clean environment to prevent dust or particles pollution inside the lens. If your focus ring
needs to be replaced please contact your local reseller or our service team at
number of the lens.
CAUTION:
Please use a proper tool to prevent from any damage on the front ring (1) or on the front element (5). Parts numbers into brackets
are referring to the next pages figures except for F200 one.
CAUTION:
After swapping the scale, please do always check the focus ring functioning. If you notice a mechanical play on the focus ring,
tighten more the seven Philips screws (6) uniformly. If the focus torque is stiff or uneven, release and tighten more uniformly the seven Philips
screws (6). Parts numbers into brackets are referring to the next pages figures.
TIP:
To help re-installing the focus scale, go to the infinity focus end-stop and put a pencil mark on the front engraved ring in front of the infinity
position. When installing the focus ring, align the infinity engraving with the mark made. After installing the focus ring, check if the marks are
correctly aligned by using a collimator, projector or camera. Proceed to a final accurate adjustment if necessary.
