Because
the material of the lens is synthetic and coated with a special
anti-reflectivity 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.
