a Safety Precautions

a Safety Precautions

Do not look at the sun or a bright light source

through the lens or camera. Doing so could result

in loss of vision. Looking at the sun directly through

the lens is especially hazardous.

Do not point the lens or camera at the sun or

photograph it. This is because the lens

concentrates the sun’s rays even when the sun is

outside the image area or when shooting with

backlight, which could cause malfunction or fire.

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.

• If the lens is taken from a cold environment into

a warm one, condensation may develop on the

lens surface and internal parts. To prevent

condensation in this case, first put the lens into an

airtight plastic bag before taking it from a cold to

warm environment. Then take out the lens after it

has warmed gradually. Do the same when taking

the lens from a warm environment into a cold one.

• Do not leave the lens in excessive heat such as in

a car in direct sunlight. High temperatures can

cause the lens to malfunction.

This device complies with Part 15 of the FCC Rules. Operation is

subject to the following two conditions: (1) This device may not

cause harmful interference, and (2) this device must accept any

interference received, including interference that may cause

undesired operation.

Do not make any changes or modifications to the equipment

unless otherwise specified in the instructions. If such changes or

modifications should be made, you could be required to stop

operation of the equipment.

This equipment has been tested and found to comply with the

limits for a class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection

against harmful interference in a residential installation. This

equipment generates, uses and can radiate radio frequency

energy and, if not installed and used in accordance with the

instructions, may cause harmful interference to radio

However, there is no guarantee that interference will not occur in

a particular installation. If this equipment does cause harmful

interference to radio or television reception, which can be

determined by turning the equipment off and on, the user is

encouraged to try to correct the interference by one or more of

the following measures:

• Reorient or relocate the receiving antenna.

• Increase the separation between the equipment and receiver.

• Consult the dealer or an experienced radio/TV technician for

You can set the focusing distance range to

1.5 m/4.9 ft. to infinity or 3 m/9.8 ft. to infinity. By

setting the suitable focusing distance range, the

actual autofocusing time can be shorter.

If you autofocus outside the set focusing distance

range, the lens may stop focusing at the start of

the focusing range; however, this is not a

malfunction.Press the shutter release button

You can use the image stabilizer in AF or MF mode.
