| 14. 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, |
En | 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. |
