Precautions
Do not disassemble, modify the lens by yourself. Do not touch the
internal parts that become exposed as the result of external force.
Do not leave the lens where it will be exposed to high temperatures,
such as in direct sunlight and an enclosed vehicle. Excessive heat may
deform the glass elements and other parts of the lens.
Whether it is attached to the camera or not, do not leave the lens under
the sun without the lens cap attached. This is to prevent the lens from
concentrating the sun’s rays, which could cause a fire.
Do not place the sun in the frame center when shooting with backlight.
Doing so might cause a fire or harm your eyes.
The camera’s built-in flash will cause barrel shadow if used with this
lens. For best results, please use an external flash unit.
Safety Precautions Maintenance Precautions
Do not touch the surface of the lens directly. Brush off any dust with
a blower. Wipe the surface with a cleaning cloth or a lens tissue.
Try a circular motion from the center outward to remove oil,
fingerprints and grime on the lens surface.
If your lens is brought directly from a cold place to a warm place,
condensation may appear on the lens. To avoid this, be sure to take
some action to protect the lens.
