How to clean the Prism exit side?
1. Wipe off the dust of the Prism exit. Use for that a dry and clean Lens cleaning cloth.
Tip: Limit the number of wipe movements. This to protect the optical coating. It is better to wipe off the
dust with one good wipe movement than with 10 soft wipe movements.
2. Is all dust removed from the Prism exit?
► If yes, stop this cleaning procedure.
► If no, wipe off the dust of the Prism exit with lens cleaner and a clean lens cleaning cloth. Polish again with a
dry one.
