LIQUID LENS CLEANING
Because the material of the lens is synthetic and coated with a special anti-reflective layer, cleaning must be done with a non-aggressive cleaning fluid. It is advised to use “Cleaning Solvent".
Before touching the lens it is advised to clean the surface of the lens by blowing clean air over it. This to avoid that little particles make scratches on the lens.
The actuator is a very precise mechanical component and may not be damaged in order to guarantee its full function. Clean the lens gently (don’t press too hard) with a soft and clean cotton bud moistened with the special lens cleaner. The direction of cleaning must be in the way as indicated in the picture above.
