Notes
Check the following points, and make sure the place where the lens is stored satisfies the following conditions.
 Store the lens only under the following ambient conditions.
Ambient storage temperature: –22 °F to 140 °F (–30 °C to 60 °C)
Ambient storage humidity: up to 60 % RH (no condensation)
 Do not suddenly move the lens from storage at a very cold ambient temperature into a warm room.
Doing so may cause the lens to fog on the inside or may cause condensation.
 Do not subject the lens to strong physical shocks or vibration.
3 (E)
Handling the product
Dealing with abnormalities
 Never allow water to enter or be spilled on the product.
Immediately stop using the product if water enters the
product. Otherwise, a fire or electric shock hazard may
result.
 Should any of the abnormalities described below occur,
immediately unplug the lens cable from the camera,
and then contact the dealer where you purchased this
product.
– Smoke, abnormal smell, or abnormal noise
– Entry of foreign objects (including metals and liquids)
inside the lens
 Do not stare at the sun or other source of high-intensity
light through the lens. Doing so may result in injury to
your eyes.
 Do not drop the lens when transporting it or when
attaching or detaching it to or from the camera head.
The lens may fall, possibly causing injury.
 Make sure all mountings are tightened securely. If any
of these mountings becomes loose, the lens may fall,
possibly causing injury.
Maintenance and inspection
 Always grasp the connector itself when connecting or
disconnecting the lens cable. Pulling on the cable portion
may result in damage to the cable, such as exposure
or breakage of the conductors. Power leaking from a
damaged cable may present a fire or electric shock
hazard.
 Unplug the lens cable and remove the lens from the
camera, before attempting to clean the lens. Never use
flammable substances such as benzene or thinner for
cleaning, as this may present a serious fire or electric
shock hazard.
 Inspect all mountings periodically (about every 6 months
to 1 year) to make sure they are securely tightened, and
tighten any loose portions.
Otherwise, the lens may fall, possibly causing injury.
Notes
 Protect the lens from strong impacts of shocks. Striking or
dropping the lens may result in a malfunction.
Notes
 Gently blow or brush away dust or dirt on the lens surface
using a lens blower or a soft lens brush. Remove any
fingerprints or other stains with a clean cotton cloth
moistened with commercially available lens cleaning fluid
or lens cleaning paper.
Gently swirl the cloth or cleaning paper over the lens
surface, starting at the center area of the lens, and then
circling gradually outward until whole lens surface has
been covered.
Be careful not to rub dust across the lens, as the lens
surface may be scratched.
 This lens is not completely waterproof, so avoid exposing
it directly to rain or snow. When the lens must be used in
rain or snow, provisions should be made to prevent the
lens from getting wet.
 A periodic inspection about once a year is recommended.
The inspection and maintenance interval depends on
the operating conditions, the frequency of use, and the
environment. If required, overhaul the lens.
 If it becomes necessary to repair this product, or to
perform any operations or adjustments not mentioned in
this Operating Instructions, contact the dealer where you
purchased this product.
 Under dusty conditions, the lens should be mounted or
dismounted with a cover placed over the mount so as to
prevent dust from entering into the interior.
 Do not bring the lens, kept in a very cold ambient
temperature, into a warm room, because the lens may
fog on the inside or condensation may occur.
In these cases, the lens cannot be used until these
problems clear.
If the lens must be used under such conditions,
countermeasures are recommended.
Storage
 Always attach the hood cap and the dust cap before
storing the lens. Storing the lens without these caps
attached may present a fire hazard. (Very bright light,
such as sunlight, may be focused by the lens and cause
a fire.)
 If the lens is to be used in adverse environments, such as
in a chemical laden atmosphere, consult with the dealer
where you purchased this product.
 Please do not pull out the cable with the power supply of
the camera turned on. It might cause the breakdown.
Note
 If the lens becomes damp because of use in fog, mist
or drizzle, wipe off the moisture with a soft dry cloth and
seal the lens together with an efficient desiccant in a
vinyl bag to remove moisture which has entered into the
interior.
