the lens while the focus lens is operating. If
external pressure is applied to the moving part,
the lens initialization may be performed to return
the focus lens to the correct position for control
purposes.

z The lens’ focusing ring is electronic.
zWhen AF operation is set to [ONE SHOT],

manual focus is possible after autofocusing
has been completed by continuing to press the
shutter button halfway. (Full-time manual focus)
However, the camera settings need to be
changed.

Image Stabilizer

This function provides image stabilization
appropriate for shooting conditions (such as
shooting still subjects, panning shots, and close­up (macro) shooting).

Set the image stabilizer switch to ON when you
want to use the Image Stabilizer.

z Set the image stabilizer switch to OFF when

you are not going to use the Image Stabilizer.

z The shorter the focusing distance is, the less the

image stabilizer effect.

z The Image Stabilizer cannot compensate for a

blurred shot caused by a subject that moved.

z The Image Stabilizer may not be fully effective

if you shoot from a violently shaking vehicle or
other transportation.

z When using a tripod, it is recommended that you

set the image stabilizer switch to OFF.

z 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.

z When shooting a still subject, it compensates for

camera shake in all directions.

z It compensates for vertical camera shake during

panning shots in a horizontal direction, and
compensates for horizontal camera shake during
panning shots in a vertical direction.

ENG-9

Image Stabilizer

The Image Stabilizer for this lens is suited to hand-held shots in the following conditions.

z In semi-darkened areas such as indoors or

outdoors at night.

z In locations where a flash cannot be used,

such as art museums and theater stages.

z In situations where your footing is uncertain.
z In situations where fast shutter speed settings

cannot be used.

z Panning shots of

vehicles, trains, etc.

ENG-10

5.

Hand-held Close-up (Macro) Shooting

This lens allows users to focus from infinity to a
magnification of 0.5x for close-up (macro) shooting.

Hold the camera steadily

Hold the camera steadily as shown in the illustration on the
right when taking hand-held close-ups (macro), and shoot
carefully to minimize camera shake and prevent focus blurring.

Taking photographs using servo AF

It is recommended that the camera AF operation is
set to [Servo AF] when taking close-up (macro) shots.

Refer to the camera’s instructions for further details.

z It is necessary to be careful with the following

during close-up (macro) shooting.

• Camera shake creates more impact than on
normal shots, and the effects of the image
stabilizing function are reduced.
Depth of field becomes extremely shallow when

•
taking close-up (macros) shots, and the focus may
blur if the camera is moved forward or backward.

z The minimum focusing distance (minimum

distance between the subject and the imaging

area) is 0.17 m/0.56 ft. The working distance

(distance between the front end of the lens and

the subject) is 70 mm/2.76 in.

Place both elbows on a steady surface such as a table.

Use your knee to
support the elbow of
the arm holding the
camera or lens.

Lean against a steady
object like a wall to support
your body and arm.

ENG-11

6.

Exposure When Taking Close-up (Macro) Shots

Setting the Exposure

When taking photographs using TTL metering,
no exposure compensation is necessary because
the light coming through the lens is measured.
With TTL metering, photographing with AE (auto
exposure) is possible at all focusing distances.
Just select the desired picture-taking mode, then
check the shutter speed and aperture before
taking a picture.

Magnification and Effective f-number

The aperture displayed on 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 has
almost no influence on the exposure for normal
picture taking. However, for close-up (macro)
shooting, the change in the effective f-number is
more than negligible.

When deciding the exposure using a hand-held
exposure meter, apply the following exposure
factor.

Magnification 1:5 1:3 1:2
Focusing distance
(m/ft.)
Effective f/No. 2.1 2.2 2.4

Exposure factor
(stops)*

* Upper values: 1/3 stops. Lower values: 1/2 stops.

zConditions of the subject are very important

when deciding on the correct level of exposure
for close-up (macro) shooting.
It is therefore recommended that you change
the exposure level as much as possible during
shooting, or that you take pictures while
checking the images on the camera’s LCD
monitor.

zDuring close-up (macro) shooting, it is

recommended that you use either the aperture­priority AE (Av) mode or manual exposure (M)
mode, in which adjustment of the depth of field
and exposure is easier.

z If the hood is not attached properly, vignetting

(darkening of the perimeter of the picture) may
occur.

zTurn OFF the power of the camera before

attaching or detaching the hood.

You can attach filters to the filter mounting thread
on the front end of the lens or on the front end of
the hood.

z Only one filter may be attached.

Macro Flash (Sold separately)

The Macro Ring Lite MR-14EX II or Macro Twin

Lite MT-26EX-RT enables flash photography up

to 0.5x magnification in E-TTL II autoflash mode.

zWhen using a macro flash and filter at the same

time, attach the flash head to the lens while the
filter is attached to the thread for attaching the
filter in the front end of the lens.

zIf a filter is attached to the macro flash, the front

end of the lens and filter contact, which hinders
focusing. It also may damage the filter or causes
the lens to fail.
