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.
14 APERTURE CONTROL 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 KAF2 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.
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.
16 MACRO LENS The D FA Macro 50mm f/2.8 and D FA Macro 100mm f/2.8 lenses enable closeup photography up to 1x magnification.
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.
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.
20 FILTERS 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.
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.
