General Precautions
Handling Precautions
 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, rst 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.
 Please also read any lens related handling precautions
listed in your camera’s instruction manual.
Shooting Precautions
 Note that there are cases in which the white ring on
the front of the lens may be reected into photographs
if the lens is held close to reective objects (glass
surface on wristwatches, for example), even if the
Macro Lites are not illuminated. This can be avoided by
attaching the hood when taking photographs.

 Video lming will be terminated once the mode
selection ring is rotated from the normal mode
towards the retracted position during lming.
 A warning will be displayed on the camera’s
LCD monitor if lming is not possible due to the
position of the mode selection ring.
 Do not attempt to forcibly rotate the mode
selection ring when it is locked. Doing so may
result in damage to the lock release mechanism.

ENG-9
 The magnication ratio represents the ratio
between the actual size of the subject and the
size of the image.
 The distance range represents the distance
between the mark (image mark) on the
camera and the subject.
 The minimum distance range from the front of
the lens to the subject (working distance) is
1.8cm in the normal mode and 1.3cm in the
super macro mode. When the camera’s focus mode is set to [MF],
focus manually by turning the focusing ring.

ENG-10
This lens is equipped with an Image Stabilizer.
This function corrects camera shake, allowing
users to capture sharp images. Also, the Image
Stabilizer automatically provides optimal image
stabilization depending on shooting conditions
(such as shooting still subjects and following
shots). Please set the Image Stabilizer ON
or OFF using the camera settings. See your
camera’s instructions for details.
Image Stabilizer [On]
Image Stabilizer [Off]
The image stabilizer in this lens is effective for
hand-held shots under the following conditions.
 Hand-held close-ups (macro)
 In semi-darkened areas such as indoors or outdoors
at night.
 In locations where ash photography is prohibited,
such as art museums and theater stages.
 In situations where your footing is uncertain.
 In situations where fast shutter settings cannot be
used.
 When panning subjects in motion.
Image Stabilizer

ENG-11
Image Stabilizer
 The shorter the subject distance from the
camera, the lesser the Image Stabilizer effect
will be.
 The Image Stabilizer cannot compensate for a
blurred shot caused by a subject that moved.
 Set the Image Stabilizer to OFF when you are
taking pictures using the Bulb setting (long
exposures). If the Image Stabilizer is set to ON,
the image stabilizer function may introduce
errors.
 The Image Stabilizer may not be fully effective
if you shoot from a violently shaking vehicle or
other transportation.
 The Image Stabilizer consumes more power
than normal shooting, resulting in fewer shots
and a shorter movie shooting time.
 When shooting a still subject, it compensates for
camera shake in all directions.
 It compensates for vertical camera shake during
following shots in a horizontal direction, and
compensates for horizontal camera shake during
following shots in a vertical direction.
 When you use a tripod, the Image Stabilizer
should be turned off to save battery power.
 Even with a monopod, the Image Stabilizer will
be as effective as during hand-held shooting.
However, depending on the shooting conditions,
there are cases in which the Image Stabilizer
effect may be less effective.

ENG-12
Hold the camera rmly
Hold the camera rmly as shown in the
illustration on the right when taking hand-held
close-ups (macro), and take the shots carefully
to minimize camera shake and prevent focus
blurring.
Taking Photographs with the Servo AF
It is recommended that the camera is set at
Servo AF when taking close-up (macro) shots.
See the camera’s instruction manual for further
details.
It is necessary to be careful of the following during
close-up (macro) shooting.
• There is a tendency for camera shake to affect
close-up (macro) shots more than normal shots,
and the effects of the image stabilizing function
are reduced.
• Depth of eld becomes extremely shallow when
taking close-up (macros) shots, and the focus
may blur if the camera is moved forward and
backward.
Taking Hand-held Close-ups (Macro)
5
Place both elbows on a steady surface such as a table.
Use your knee to support
an arm holding the camera.
Lean against a steady
object like a wall.

ENG-13
Setting the Exposure
When taking photographs using TTL metering,
no exposure compensation is necessary to
meter the light coming through the lens.
With TTL metering, AE (autoexposure) is
possible at all focusing distances. Just set the
desired picture-taking mode, then check the
shutter speed and aperture before taking the
picture.
Magnification and Effective f-number
The aperture displayed by the camera assumes
that the focus is set to infinity. The actual
aperture (effective f-number) becomes darker
(effective f-number increases) at closer focusing
distances (magnification increases). This does
not cause exposure problems for normal picture-
taking. However, for closeup photography, you
cannot ignore the change in the effective
f-number.
 Conditions prevalent with the subject are very
important when deciding on the correct level
of exposure for close-up (macro) shots. It is
therefore recommended that exposure levels are
amended as much as possible during shooting,
or that the image of the subject is checked on
the camera’s LCD monitor.
 Using either the aperture-priority AE (Av) mode
or manual exposure (M) mode is recommended
for close-up (macro) photography, as these
make it easier to adjust the depth of eld and
exposure.

Exposure When Taking Close-up (Macro) Shots

ENG-15
Macro Lite A
Macro Lite B
The Macro Lites on the front of the lens shine
light on the subject during close-up (macro)
photography to facilitate shooting. There are two
light-emitting Macro Lites located on both sides
of the lens, and it is possible to illuminate both
simultaneously or either of them independently.
1. Set the mode selection ring to either the
normal mode or the super macro mode.
2. Press the Macro Lite ON button to illuminate
the Macro Lites.
Macro Lites

 The Macro Lites can only be illuminated when
the power to the camera is switched on.
 Remove the hood when using the Macro Lites.
The use of a single Macro Lite will add shadow to
the subject and add a sense of three-dimensionality
to photographs.

ENG-16

■ Switching Between Both Macro Lites
and a Single Macro Lite
 Hold down the Macro Lite ON button with the
light illuminated to alternate between both
lights and a single light.

ENG-17
Macro Lites
 The Macro Lites cast shadows from the camera
and lens onto the subject during close-up
(macro) photography to facilitate shooting and
improve the end result. They are not designed to
shine sufcient light on subjects when shooting
in dark locations.
 The Macro Lites are extinguished when the
camera’s power-saving function (Auto Power Off)
turns off the power.
 T
he illumination status will not be saved once the Macro
Lites have been extinguished when the power to the
camera has been switched off and the lens retracted.
 More battery power is consumed when the
Macro Lites are in use than when they are
not in use, which will reduce the number of
photographs that can be taken and the amount
of time that videos can be lmed.
 T
he Macro Lites will be concealed when the hood
is attached, so don’t forget to switch them off.
 A fter pressing the shutter button halfway, don’t
change the Macro Lite status when shooting.
Since pressing the shutter button halfway locks the
exposure*, it may not be possible to shoot in standard
exposure if the Macro Lite status has changed.
* Differs according to the camera’s photometry and
AF settings. For details, please check your camera’s
instruction manual.
Hood
8
The ES-22 lens hood plays the following roles:
 I
n addition to blocking out damaging light, it also protects
the lens from rain, snow, dust and other elements.
 It prevents the white ring on the front of the
lens from being reected back into images.
 It acts as an adapter when lters are being used.
Screw the hood rmly and correctly onto the
front of the lens.
 Attaching the hood at an angle may damage the
outside of the lens.
 I
f the hood is not attached properly, vignetting
(darkening of the perimeter of the picture) may occur.
 Remove the hood when using the Macro Lites.
It is possible to attach the lens cap to the front of
the hood when it is attached to the lens.

ENG-18
Hood
You can attach lters (which are 43 mm in
diameter) to the lter mounting thread on the
front of the hood.
1. Attach the hood.
2. Attach the lter to the front of the hood.
 Filters cannot be used unless the hood is
attached.
 Only one lter may be attached.
