Q: How to maintain the lens? Can we use alcohol on it?
A: Please do not use toilet paper, alcohol, stain cleaner, and gasoline,
etc. to rub the lens. On the lens is a thin plating film, which is to
prevent unnecessary light wave from entering the camera. Improper
rubbing will cause tear or scar on the lens.
Please use lens wiper or clothe with minimum clean liquid specified
for lens and wipe in concentric circles.
