Foreward Thank you for purchasing the smc PENTAX lens. This operating manual applies to all of the smc PENTAX FA and FA J lenses. Please also read your camera's operating manual. * In this manual, the "smc PENTAX - FA lens" is referred to as "FA lens" and the "smc PENTAX - FA J lens" as the "FA J lens".
USING YOUR LENS SAFETY 1 Although we have carefully designed these lenses for safe operation, please pay special attention to items marked with the following symbols when using this product. WARNING This symbol indicates precautions that if not followed, could result in serious injury to the user.
2 WARNING • Never look at the sun through the lens or camera. Serious damage to the retina, or total loss of eyesight may occur. • Wrapping the strap around your neck is dangerous. Make sure that small children do not get the strap caught around their neck.
PRECAUTIONS AND LENS MAINTENANCE 3 1. Storage and mildew prevention • Take the lens out of the protective case or camera bag, and store it in a dry, well-ventilated place. • Avoid storing the lens in a poorly ventilated location such as a closet, ward- robe, drawer, vehicle, or where insect repellent or medicine is kept.
4 5. Avoid subjecting the lens to rapid changes in temperature, otherwise con- densation may occur on both the inside and the outside of the lens. Put the lens in a plastic bag or camera bag, and take it out after the lens has reached ambient temperature.

9 A zoom lens has two rings: The focusing ring at the front of the lens and the zoom ring behind it. Turn the zoom ring to obtain the desired angle of view (focal distance). * Whenever you turn the zoom ring to change the angle of view (focal distance), the focus may also change slightly.
Changing the Lens 10 1 . Align the mount index red dots on the camera body and lens and attach the lens. Turn the lens clock- wise until it locks in place. 2. To detach the lens, hold down the camera's lens unlock button, then turn the lens counterclockwise.
Finger Point on Limited Lenses Lens Cap 11 You can easily attach a Limited lens by aligning the finger point on the lens with the camera's lens unlock button. Limited lenses FA 31mm f/1.8AL Limited FA 43mm f/1.9 Limited FA 77mm f/1.8 Limited To remove the lens cap, squeeze the tabs as shown in the illustration.
Focusing 12 To switch between autofocusing and manual focusing, use the camera's focus mode lever. For details, refer to your camera's instruction manual. * For FA lenses, see page 13. * For non-autofocus cameras, use manual focusing. Autofocusing Press the shutter button halfway to autofocus.
13 FA lenses With FA lenses, shift the focus- ing ring forward or back to switch between autofocus and manual focus. Setting autofocus Push the focusing ring forward until you can see AUTO FOCUS. * When the lens is set for autofocus, the focusing ring locks.
14 * If your camera has a K AF2 mount, you can still switch between auto- focus and manual focus with the lens focusing ring even when the camera has been set to autofocus. * If you have a camera (such as the SF-series) having a K AF mount, set both the camera and lens focus mode switch to the same setting.
Setting the Aperture [A (Auto) Lock Switching] 15 To set the aperture ring to A [Auto], hold down the Aperture A-lock but- ton and align the A index with the white-line index. To set the aperture ring to another setting, hold down the Aperture A-lock button and turn the aperture ring.
16 About the Zoom Lens Aperture Zoom lenses whose maximum aperture varies depending on the focal length have a [Minimum length] aperture index for the shortest focal length and a [Maximum length] aperture index for the longest focal length.
17 Apertures and Click Stops Certain lenses have a white dot next to the maximum aperture. The white dot indicates a difference of one aper- ture stop.
Using the Infrared Index If you use infrared film with an R2 or O2 filter, the point of focus differs from normal shooting (with visible light). This means the point of focus must be corrected. * Infrared film cannot be used with the MZ-S, MZ-60, and cam- eras since these cameras use infrared light to detect film transport operations.
19 Zoom Lens Infrared Index With a zoom lens, the focusing cor- rection amount for infrared film shoot- ing varies depending on the focal length. As shown in the illustration, zoom lenses have an infrared index. Correct the focus with respect to the focal length used.
Lens Hood 20 The lens hood can be round, square, or built-in. Using a lens hood is rec- ommended for preventing internal lens reflections. Suitable hoods are listed on the next page. Note: * Do not use a lens hood if you are using the camera's built-in flash.

22 Attaching a Round Lens Hood Screw-on Type Screw the hood on to the front of the lens. Bayonet Type Attach the hood to the front of the lens and turn the hood clockwise until it snaps in place. To detach the lens hood, follow this procedure in reverse.
23 Attaching a Square Lens Hood 1 . The hood attaches in the same way as a lens cap. While holding down the two knurled tabs, attach the hood to the front of the lens. 2. The square hood should be posi- tioned horizontally on the lens. If it is tilted, vignetting may occur.
24 Using the Built-in Lens Hood To use the built-in lens hood, pull it out from the lens. In the case of the FA 600mm f/4 lens, the built-in lens hood is threaded. To extend or retract it, turn the hood. For details, see the FA lens instruction manual.
25 PL Filter Window Certain hoods also have a PL filter window. This enables you to easily rotate any polarizing or circular polar- izing filter attached to the lens. Lenses with a PL filter window z FA 35mm f/2AL z FA J18-35mm f/4-5.6AL Using the PL filter window 1.
26 2. From the PL filter window, turn the polarizing or circular polarizing fil- ter. 3. Reattach the PL filter window cap. * Before shooting, be sure the cap has been reattached so that the hood can provide the maximum effect. FA lens-Body.indd 26 FA lens-Body.
Tripod Mount 27 The FA 600mm f/4 lens has a tripod mount so you can mount the lens on a tripod. Switching between horizontal and vertical shooting Loosen the lens orientation lock screw and turn the lens by 90˚ left or right. Then tighten the lens orientation lock screw.
Filters Select the filter matching the lens filter size, then screw it onto the front of the lens. * The FA 600mm f/4ED (IF) lens has a filter holder in the rear to hold the 43mm filter provided with the lens. For details, see the FA lens instruction manual.
29 Note: Using a Circular Polarizing Filter * In the case of the FA 77mm f/1.8 Limited lens, attaching certain dis- continued circular polarizing filters (including the PENTAX Type-A Circular Polarizing Filter) prevents the built-in hood from being pulled out.
Cautions When Using Flash 30 With the built-in flash Use the built-in flash for subjects at least 0.7 meter away. If the subject is closer than 0.7 meter, overexposure may result. The built-in flash can usually be used with a lens as long as the | | symbol does not blink in the camera as a warning.
