aSafety Precautions
aSafety 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.
• 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.
Handling Cautions• 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
wa rm  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.

See your camera’s instructions for details on
mounting and detaching the lens.
•
After detaching the lens, place the lens with the
rear end up to prevent the lens surface and
electrical contacts from getting scratched.
• If the contacts get soiled, scratched, or have
fingerprints on them, corrosion or faulty
connections can result. The camera and lens
may not operate properly.
• If the contacts get soiled or have fingerprints on
them, clean them with a soft cloth.
• If you remove the lens, cover it with the dust
cap. To attach it properly, align the lens mount
index and the 
Kindex of the dust cap as shown
in the diagram, and turn clockwise. To remove it,
reverse the order.
1.Mounting and Detaching the Lens2.Setting the Focus Mode
After autofocusing in ONE SHOT AF mode, focus
manually by pressing the shutter button halfway
and turning the focusing ring. (Full-time manual
f ocus)
To   shoot in autofocus (AF) mode, set the focus
mode switch to AF.
To   use only manual focusing (MF), set the focus
mode switch to MF, and focus by turning the
f ocusing ring. The focusing ring always works,
regardless of the focus mode.

Y
ou can set the focusing distance range to 
0.48 m/1.6 ft. to infinity or 1.5 m/4.9 ft. to infinity.
By setting the suitable focusing distance range,
the actual autofocusing time can be shorter.
3.Switching the Focusing
Distance Range
If you autofocus outside the set focusing distance
r ange, the lens may stop focusing at the start of
the focusing range; however, this is not a
malfunction. Press the shutter release button
halfway again.
4. Hood
The ET-78 II hood can keep unwanted light out
of the lens, and also protects the front of the lens
from rain, snow, and dust.
Attach and align the hood to the hood mount on
the front of the lens, and turn the hood as shown
by  the arrow to secure it.
The hood can be reverse-mounted on the lens
f or storage.
•P art of the picture may be blocked if the hood is
not attached properly.
• When attaching or detaching the hood, grasp
the base of the hood to turn it. To prevent
deformation, do not grasp the rim of the hood to
turn it.
• Remove the hood when using the macro flash.

6. Depth-of-Field Scale
The depth of field is the distance in front of and
behind the plane of focus on the subject that
appears sharp. The depth of field is indicated by
the area between the depth-of-field scale lines
below the distance scale.
The number on the scale is the F value.
The depth-of-field scale is an approximate
indicator.
5. Infinity CompensationMark
To   compensate for shifting of the infinity focus
point that results from changes in temperature.
The infinity position at normal temperature is the
point at which the vertical line of the L mark is
aligned with the distance indicator on the
distance scale.
F or accurate manual focusing on subjects at
infinity distance, look through the viewfinder while
rotating the focusing ring.

7. Picture Taking
•Image quality deteriorates near the minimum
aperture opening due to diffraction.
• The magnification refers to the ratio between the
subject’s size and the corresponding image size
on the focal plane. On the distance index, it is
indicated as 1:x.
•T o prevent camera shake, using a Remote
Switch (both sold separately) and tripod is
recommended.
•T o check the depth of field, press the camera’s
depth-of-field preview button.
Normal PhotographyThe lens can be used as a telephoto lens for
normal photography.
Closeup PhotographyClose-up photos (minimum focusing distance of
0.48m) up to 1x (life-size) magnification are
possible. The minimum focusing distance is the
distance from the subject to the film plane. The
distance from the front of the lens to the subject
(working distance) is about 0.25m.
When focusing, you can give priority to framing
or to magnification.
[Framing Priority]While looking through the viewfinder and framing
the subject, focus with the AF or MF mode.
[Magnification Priority]1. Set the lens’ focus mode switch to MF.
2. Set the magnification. While referring to the magnification scale on
the lens, turn the focusing ring to the desired
magnification. 3. Focus the subject.
While looking through the viewfinder, move the
camera forward or back to find the point of
focus.
4. Touch up the focus. Turn  the focusing ring for fine focusing.
Since macro shots have a very shallow depth of
field, focus carefully to obtain proper sharpness.

8. About Exposure
•The correct exposure for a close-up shot largely
depends on the subject. Therefore, it is
recommended to take several shots of the same
subject at different exposures.
• When taking close-up shots, it is recommended
to use aperture-priority AE (Av) or Manual (M)
picture-taking modes, because depth of field
and exposure are easy to adjust in those
modes.
Setting the ExposureWhen 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-numberThe 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.
When you use a handheld exposure meter to
set the exposure, you must take into account
the exposure factor shown in the following
table.
Magnification 1:10 1:5 1:3 1:2 1:1.5 1:1.2 1:1
Effective f/No. 3.8 4 4.3 4.7 5 5.4 5.8
