from dust.

Please read this instruction manual and familiarize yourself with the functions of
the lens, the operating method, and cautions for handling the product correctly
prior to use. Also refer to the instruction manual of the camera you are using with

We recommend that you familiarize yourself completely with the following items to
ensure proper use of the lens. 

It is dangerous to look at the sun through the lens directly. Doing so may
seriously impair your vision.
The lens is a precision optical product, so dropping or applying an excessive
impact to the lens may cause product failure.
Attach or detach the lens only when the camera is turned off.
Be careful not to apply an impact when attaching the lens. The lens is a
precision optical product, so dropping or applying an excessive impact to the lens
may cause product failure.
In order to use the lens safely, attach or detach the lens while the camera is
turned off.
Be careful not to touch or contaminate the contact point on the mount. If
electronic signals are not transmitted between the camera and the lens smoothly,
a malfunction may occur.
If the camera is not used for a certain period of time, the lens will enter sleep
mode. When the lens is in sleep mode, you will be unable to manually focus it
even if the camera is turned on. If manual focus is impossible, press the shutter
release to bring the lens out of sleep mode. You will then be able to use the
manual focus function. (The amount of time it takes for the lens to enter  sleep
mode may vary from camera to camera.)
When turning on the camera or pressing the shutter release to use the lens while
it is in sleep mode, the camera will focus and reset aperture position for
approximately 1 to 2 seconds and the view through the viewfinder may be out  of
focus temporarily.

This is a normal reset operation and not a failure of the lens.

Do not store the lens without a lens cap in a location with direct sunlight, such as
inside a vehicle. Direct sunlight passing through the lens may be concentrated,
causing a fire.

If the lens is placed in a hot location, damage or distortion may occur, resulting
in performance problems.

Store the lens in a dry, well-ventilated location. Avoid direct sunlight, and do not
store the lens with naphthalene or mothballs.

Avoid using the lens in a location with drastic temperature changes. In particular,
if you move a lens that has been chilled in a cold location to a warm location,
moisture in the air may be concentrated outside or inside the lens, causing
product failure, or the production of mold. In such a case, keep the lens in a
plastic bag or an exclusive camera bag and take it out when the temperature of
the lens becomes similar to the peripheral temperature.

Keep the lens out of the reach of children. Failure to do so may cause an
accident or personal injury.

If the lens surface gets dirty, dust it off using a lens blower or a brush and wipe it
with a soft, clean cloth (cleaning tissue, cotton cloth, etc.)

When dusting or cleaning the lens, do not use organic solvents such as thinner,
alcohol, or benzene.

When cleaning the lens, put a small amount of ethanol or lens cleaner on a soft,
clean cloth or cleaning paper and wipe the lens by circling outwards from the
center.
