12. Lens care
• When the lens is not in use, set the tilt and shift amount to “0.”
The lens has many moving parts and can be easily soiled by dust,
dirt or water drip.
• Clean the lens surfaces with a blower brush. To remove dirt and
smudges, use a soft, clean cotton cloth or lens tissue moistened
with ethanol (alcohol) or lens cleaner. Wipe in a circular motion
from center to outer edge, taking care not to leave traces or
touch other parts of the lens.
• Never use thinner or benzene to clean the lens as this might
damage it, result in a fire, or cause health problems.
• To protect the front lens element, an NC filter is recommended
at all times. A lens hood also helps protect the front of the lens.
• When storing the lens in its lens case, attach both front and
rear caps.
• When the lens will not be used for a long time, store it in a cool,
dry place to prevent mold. Also store the lens away from direct
sunlight or chemicals such as camphor or naphthalene.
• Do not get water on the lens or drop it in water as this will cause
it to rust and malfunction.
• Reinforced plastic is used for certain parts of the lens. To avoid
damage, never leave the lens in an excessively hot place.
