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.
Notes on Use
• Do not leave the lens exposed to the sun or a bright
light source. Internal malfunction of the camera body
and lens, smoke, or a fire may result due to the effect
of light focusing. If circumstances necessitate leaving
the lens in sunlight, be sure to attach the lens caps.
• When shooting against the sun, keep the sun
completely out of the angle of view. Otherwise, solar
rays may be concentrated at a focal point inside
the camera, causing smoke or a fire. Keeping the
sun slightly out of the angle of view may also cause
smoke or a fire.
• When carrying a camera with the lens attached,
always firmly hold both the camera and the lens.
• This lens is not water-proof, although designed with
dust-proofness and splash-proofness in mind. If using
in the rain etc., keep water drops away from the lens.
• While a camera with the lens attached is turned
off, the internal components of the lens may be
put in motion. This, however, does not indicate a
malfunction.
Precautions on using a flash
• When using a flash, always remove the lens hood and
shoot at least 1 m (3.3 feet) away from your subject.
• With certain combinations of lens and flash, the lens
may partially block the light of the flash, resulting in a
shadow at the bottom of the picture. In such a case,
adjust the shooting distance before shooting.
Vignetting
• When using the lens, the corners of the screen
become darker than the center. To reduce this
phenomena (called vignetting), close the aperture by
1 to 2 stops.
