12
Using the Quick-Shift Focus System ( -series cameras only)
If you use the lens with an camera and the focus mode is set to autofocus, you can
focus manually after autofocus is achieved. Just turn the focusing ring to manually touchup the focus. You can do this without switching the focus mode to MF.
How to use the Quick-Shift Focus System
1. Using Autofocus
Set the camera’s focus mode switch to autofocus, then press the shutter button halfway
(or press the AF button) to autofocus.
2. Adjust the focus by turning the focusing ring.
3. Finally, press the shutter release button to take the picture.
CAUTION
• During the autofocus operation, the focusing ring does not rotate. Do not
turn the focusing ring during the autofocus operation. Doing so will cause a
malfunction.
• When using the Quick Shift Focus System, keep pressing the shutter button
(or AF button) after you achieve focus and before taking the picture. If you
let go of the shutter button before taking the picture, you will have to focus
all over again when you press the shutter button again.
HOW TO USE THE INFRARED INDEX
13
If you use infrared film and attach an R2 or O2 filter to the lens to take infrared pictures, the
point of focus will be different from when you shoot normally (with visible light). A focusing
correction will be necessary. As shown above left, memorize the focusing point on the lens
distance scale when viewed through the viewfinder and turn the focusing ring until the point
you memorized aligns with the infrared index, red dot, as shown above right.
• Infrared film can not be used for MZ-S, MZ-60 and *ist since infrared ray is used for
detecting device of film transport. It will expose infrared film in the camera.
• Turn the focusing ring in the MANUAL focus mode only.
• For the exposure control requierd in this special photography, see the information
supplied with the infrared film.
APERTURE CONTROL
14
Setting the aperture to “A”(Auto)
Turn the aperture ring to align the aperture-A index with the white line while depressing the
Aperture-A-lock button. The aperture ring can be released from “A” in the same manner
to set your desired f-stop manually.
• If the camera has the K
AF2 lens mount and the aperture is not set to A, the approximate
aperture setting will be displayed on the display panel and in the viewfinder.
• If the camera has the K lens mount which has no electronic contacts to transmit the lens
information, set the aperture to any f-stop other than A.
15
Aperture Ring Cautions
The following restrictions apply to the respective cameras below.
-series,
MZ-60, MZ-30
MZ-50
If the camera is set to the default settings and the aperture ring
is not set to A, the camera will not work. Be sure to set the
aperture ring to A and set the aperture with the camera. Although
you can use the Custom Function menu or C Custom menu to
enable camera operation while the aperture ring is not set to A,
restrictions will apply. Refer to the camera’s manual for details.
If the aperture ring is not set to A, the camera will not work. Be
sure to set the aperture ring to A and set the aperture with the
camera.
MACRO LENS
16
The D FA Macro 50mm f/2.8 and D FA Macro 100mm f/2.8 lenses enable closeup
photography up to 1x magnification.
Clamp Switch
17
Magnification Scale
The magnification is indicated by denominators on the distance scale. “1” indicates “1x”.
For example, “1” on the magnification scale at the top will make the magnification 1/1x. If
you want to set the magnification first, turn the focusing ring to set the desired
magnification. Then focus the subject by moving the camera forward or back.
18
About the Clamp Switch
The D FA Macro 50mm f/2.8 and D FA Macro 100mm f/2.8 lenses are equipped with a
Clamp switch which is convenient for manual focus.
The Clamp switch locks the manual focus position. You can use it when taking close-ups
with a copy stand, for example.
Using the Clamp Switch
Focus manually, then set the Clamp switch to ON.
The point of focus will be locked. Autofocus will also be disabled.
• Do not turn the focusing ring forcibly while setting the Clamp switch to ON because there
is a slight possibility that the point of focus may change.
• If you use the Clamp switch with any of the following cameras, be sure to first set the
camera’s focus mode switch to MF.
Z-10, Z-20, Z-20P, Z-50 P, Z-70P, MZ-5, MZ-10, and MZ-50
LENS HOOD
19
Using a lens hood is recommended to block stray light from entering the lens. The stray
light’s internal reflections degrade the image quality.
Lens hood for D FA lens
How to attach
Put the hood on the lens, and turn it as shown by the arrow until it clicks in place.
✍ Memo:
• When the lens hood is not in use, it can also be turned around and attached in the
reversed position.
FILTERS
20
The filter is mounted into the screw thread in front of the lens.
Precaution on filters
• Since the filter becomes a part of the optics when attached on the lens, handle it in the
same way you handle the lens with care to dust, dirt and scratches. Avoid using more
than one filter, unless it is a circular polarizing filter. Using two or more filters will degrade
the image quality and the filter effect will not be obtained.
• Use a circular polarizing filter with Autofocus camera for proper exposure and
autofocusing.
PRECAUTIONS WHEN USING THE LENS WITH A FLASH
21
Built-in Flash
The built-in flash can not be used when the distance is less than 0.7m. When the flash is
used within 0.7m, it causes incorrect exposure control.
• If the built-in flash is used with the lens hood attached to the lens, the flash light will be
blocked by the lens hood. Always make sure to remove the lens hood before using the
built-in flash.
