Notes on use

• Do not leave the lens in direct sunlight. If sunlight is focused onto a nearby

object, it may cause a ﬁre. If circumstances necessitate leaving the lens in direct
sunlight, be sure to attach the lens cap.

• Be careful not to subject the lens to mechanical shock while attaching it.
• Always place the lens caps on the lens when storing.
• Do not keep the lens in a very humid place for a long period of time to prevent

mold.

• After attaching the lens, do not carry the camera by holding the lens.
• Do not touch the lens contacts. If dirt, etc., gets on the lens contacts, it may

interfere or prevent the sending and receiving of signals between the lens and the
camera, resulting in operational malfunction.

Precaution for ﬂash use
With certain of lens/ﬂash combinations, the lens may partially block the light
of the ﬂash, resulting in a shadow at the bottom of the picture. When using a
built-in camera ﬂash, make sure to remove the lens hood and shoot from at
least 1m (3.3feet) away from your subject.

Vignetting
When you use 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.

Condensation
If your lens is brought directly from a cold place to a warm place,
condensation may appear on the lens. To avoid this, place the lens in a plastic
bag or something similar. When the air temperature inside the bag reaches
the surrounding temperature, take the lens out.

Cleaning the lens
• Do not touch the surface of the lens directly.
• If the lens gets dirty, brush off dust with a lens blower and wipe with a soft,

clean cloth (Cleaning Cloth KK-CA (optional) is recommended).

• Do not use any organic solvent, such as thinner or benzine, to clean the lens or

the camera cone.

 Attaching/detaching the lens

To attach the lens (See illustration

-.)

Remove the rear and front lens caps and the camera body

cap.
• You can attach/detach the front lens cap in two ways, (1) and (2). When you

attach/detach the lens cap with the lens hood attached, use method (2).

Align the orange index on the lens barrel with the orange

index on the camera (mounting index), then insert the lens
into the camera mount and rotate it clockwise until it locks.
• Do not press the lens release button on the camera when mounting the lens.
• Do not mount the lens at an angle.

To remove the lens (See illustration

-.)

While pressing and holding the lens release button on the
camera, rotate the lens counterclockwise until it stops, then
detach the lens.

 Attaching lens hood

It is recommended that you use a lens hood to reduce ﬂare and ensure
maximum image quality.
* The 50mm F2.8 Macro does not include an external lens hood. The lens barrel

functions as a lens hood by design.

100mm F2.8 Macro:
Fit the hood into the mount on the end of the lens barrel and
rotate the hood clockwise until it clicks.
35mm F1.4 G:
Align the red line on the lens hood with the red dot on the lens.
Turn the hood clockwise until the red dot on the hood meets the
red dot on the lens and it clicks into place.
• When using a built-in camera ﬂash, make sure to remove the lens hood to avoid

blockage of the ﬂash light.

• If a marking (red line, red dot, etc.) is provided, attach the lens hood properly.

Otherwise, the lens hood may interfere with the desired effect or may appear in
pictures.

• When storing, turn over the lens hood and place it onto the lens backwards.

 Focusing

When using the auto focus, the camera focuses the lens automatically.
When focusing manually, set your camera to the manual focus and rotate the
focusing ring while looking through the viewﬁnder. The focus signal in the
viewﬁnder indicates the current degree of the focus.
• The focusing ring can be rotated slightly past the inﬁnity to provide accurate

focusing under various operating temperatures. Do not rotate the focusing ring
all the way to the end when focusing manually even at inﬁnity. Look through the
viewﬁnder and set the focus precisely.

Focus-hold button

–(2)

While the focus-hold button is pressed, auto focus function is suspended and
the focus is ﬁxed for shooting.
• The function of the focus-hold button can be changed on cameras with custom

function capability. Refer to the camera manuals for details.

Focus-range limiter

–(3)

For quick focusing, the focusing range can be limited to close or far range,
depending on the distance to your subject.

Close-focusing range

Far-focusing range

50mm F2.8 Macro

20 - 27cm

30cm -

∞

100mm F2.8 Macro

35 - 54cm

59cm -

∞

To focus on subjects at close range (see the table above), set focus anywhere
near the subject and then set the focus-range limiter to LIMIT; the focusing
range is limited to Close-focusing range. Likewise, when shooting subjects
at far range, set the focus anywhere near the subject and then set the focus-
range limiter to LIMIT; the focus range is limited to Far-focusing range. Set
the focus-range limiter to FULL to allow the entire focusing range.
• Set the focus-range limiter to FULL, when shooting a subject between the Close

and Far focusing ranges.

Depth-of-ﬁeld scale

When focus is set on a subject, anything at that same distance will appear
sharp, and anything within a certain range before and beyond the subject will
also appear in focus; this is called depth of ﬁeld. Depth of ﬁeld depends on
the subject distance and aperture you choose and is indicated by the lines on
the depth-of-ﬁeld scale corresponding to the aperture.

Macro lens depth of ﬁeld (50mm F2.8 Macro, 100mm F2.8
Macro)
Refer to the depth-of-ﬁeld table

 for details on depth of ﬁeld.

• The depth-of-ﬁeld scale and depth-of-ﬁeld table

 is for 35mm-format

cameras. The depth-of-ﬁeld is shallower when you use Digital Single Lens
Reﬂex Cameras equipped with an APS-C sized image sensor.

Magniﬁcation ratios

The magniﬁcation scale is located on the extending section of the lens barrel.
The line on the magniﬁcation scale which the edge of the outer lens barrel
overlaps indicates the current magniﬁcation ratio (1:1 in illustration

).

• As the magniﬁcation increases, the camera is more vulnerable to shaking. Use a

tripod to steady the camera when shooting.

Exposure Compensation (when using a hand-held
exposure meter, etc.)

As the magniﬁcation increases, the amount of light reaching the image sensor
decreases. This is automatically compensated in all autoexposure modes, or
in the manual exposure mode as long as the exposure is adjusted according to
the camera’s meter index. If your camera is set to the manual exposure mode
and you are using a hand-held exposure meter, or if your camera is set to the
manual exposure mode and you are using the Manual Flash Control function
available on some external ﬂash units, refer to the exposure compensation
table

, and adjust exposure accordingly.

The value for equivalent 35mm-format focal length is based on Digital Single Lens Reﬂex Cameras equipped with an APS-C sized image sensor.

The value of angle of view 1 is based on 35mm-format cameras, and that of angle of view 2 is based on Digital Single Lens Reﬂex Cameras equipped with an APS-C sized

image sensor.

Minimum focus is the shortest distance from the image sensor to the subject.

• This lens is equipped with a distance encoder. The distance encoder allows more accurate measurement (ADI) by using a ﬂash for ADI.
• Depending on the lens mechanism, the focal length may change with any change of the shooting distance. The focal length assumes the lens is focused at inﬁnity.
