Lens Storage and Maintenance
• Store the lens in dry and well ventilated areas.
• Do not store the lens in a closet, car, or confined area with chemicals.
• Do not store the lens in high temperature or humidity.
• The lens is not waterproof. Be careful not to allow it to get wet when using it near water.
• Do not use chemicals such as thinner, alcohol, or benzene to remove dust.
• Do not drop the lens or apply excessive shock to it. The lens is a precise optical product.
• Avoid using the lens anywhere there is a sudden temperature change. Keep the lens in a plastic
bag or a camera case to prevent condensation from forming on the inside or outside of the lens.
• When not using the lens, place the lens cap and lens mount cover on the lens to prevent
contamination from foreign particles and protect the lens.
• Do not keep the camera mounted on a tripod without the lens cap. The inside of the camera can
be damaged by direct sunlight.
• Check the lens once every year or two for best performance.
• Do not apply excessive force to the front of the lens.
