2 PRECAUTIONS AND LENS MAINTENANCE

1. Storage and mildew prevention

Take the lens out of the protective case or camera bag, and store it in a dry, well-ventilated place.

Avoid storing the lens in a poorly ventilated location such as a closet, wardrobe, drawer, vehicle, or where insect repellent or medicine is kept.

Avoid storing the lens in areas of high temperature and humidity, where there is a risk of mildew growth. Store the lens with a desiccant in a dry cabinet, airtight container, or plastic bag. (Leaving a saturated desiccant in the storage container can cause damage to the lens. Be sure to read the instructions that come with the desiccant before use.)

2.The following lenses are dust and water resistant.

(DA 300mm f/4ED [IF] SDM, DA 200mm f/2.8ED [IF] SDM, DA 16-50mm f/2.8ED AL [IF] SDM, DA 50-135mm f/2.8ED [IF] SDM)

Lenses other than those listed above are not dust and water resistant. Be careful not to allow dust, dirt, water, harmful gases, salt, or other materials to get on those lenses.

3.When the lens is not attached to the camera body, attach both the supplied lens cap and lens mount cap to protect it from dust, etc.

4.Never use any organic solvent such as thinner, alcohol, or benzine, etc. to remove dust on the lens.

5.The lens is a precise optical instrument. Be careful not to let it fall, or subject it to strong shocks or pressure. Use a cushion or similar pad to protect the lens from the vibrations of motorcycles or other vehicles, boats, etc.

6.Avoid subjecting the lens to rapid changes in temperature, otherwise condensation can occur on both the inside and the outside of the lens. Put the lens in a plastic bag or camera bag, and take it out after the lens has reached ambient temperature.

7.Do not leave the camera with the lens cap off attached to a tripod or other rigid camera support. The inner parts of the camera can be damaged by direct sunlight.

8.Have the lens inspected by a dealer every one or two years to maintain its high performance.
