About the smc PENTAX-FA/FA J Lens 7 [Single Focal Length Lens] FA lens-Body.indd 7 Focusing ring Front-ring threads Distance scale 15 8 2 10 3 50 4 8 5.6 A 22 16 11 .4 2.
8 [Zoom Lens] Focusing ring Distance scale Aperture index {long focal length} Aperture A-lock button Zoom ring Aperture ring (note) Aperture index {short focal length} Note: The following lenses do not have an aperture ring: FA J 18-35mm f/4-5.6AL, FA J 28-80mm f/3.5-5.6AL, and FA J 75- 300mm f/4.5-5.8AL. The aperture is controlled at the A [Auto] setting. Therefore, the lens is not compatible with cameras and accessories which are not compatible with the A setting. FA lens-Body.
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. First turn the zoom ring, then focus. FA lens-Body.indd 9 About the zoom ring Turning the zoom ring to the right gets a [Telephoto] effect, making the subject look larger.
10 Changing the Lens 1. Align the mount index red dots on the camera body and lens and attach the lens. Turn the lens clockwise until it locks in place. 2. To detach the lens, hold down the camera's lens unlock button, then turn the lens counterclockwise. * When attaching a lens, do not press the camera's lens unlock button. Doing so causes improper lens attachment. * After attaching a lens, turn the lens counterclockwise slightly to make sure the lens is locked in place. FA lens-Body.
Finger Point on Limited Lenses Lens Cap 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. FA lens-Body.indd 11 11 * When not using a lens, be sure to attach the lens cap. * For the FA 43mm f/1.9 Limited lens, attach the lens cap to the hood.
12 Focusing 15 3 10 8 6 2 1.5 ft m 50 A 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. FA lens-Body.indd 12 22 16 11 8 5. 64 2 821 4 Autofocusing Press the shutter button halfway to autofocus. * During autofocusing, the focusing ring rotates so do not touch it.
13 Setting autofocus Push the focusing ring forward until you can see AUTO FOCUS. * When the lens is set for autofocus, the focusing ring locks. FA lenses With FA lenses, shift the focusing ring forward or back to switch between autofocus and manual focus. FA lens-Body.indd 13 Setting manual focus Pull the focusing ring until AUTO FOCUS is hidden. Turn the focusing ring to focus manually.
14 * If your camera has a KAF2 mount, you can still switch between autofocus 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 KAF mount, set both the camera and lens focus mode switch to the same setting. If the camera is set to autofocus [AF single] and the lens is set to manual focus, you cannot take a picture until the camera's focus indicator lights.
Setting the Aperture [A (Auto) Lock Switching] 15 8 ft 10 3 2 m 22 16 8 A 50 22 16 11 8 5 .6 4 To set the aperture ring to A [Auto], hold down the Aperture A-lock button 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. FA lens-Body.indd 15 15 15 8 ft 10 3 2 m 22 16 8 50 5.6 4 2.8 2 1.
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. To set the aperture to A [Auto], turn the aperture ring to the white [Short focal length index] at the center (regardless of the focal length) as shown in the illustration. For the longer focal lengths, if you want FA lens-Body.
17 Apertures and Click Stops Certain lenses have a white dot next to the maximum aperture. The white dot indicates a difference of one aperture stop. For example, as shown on the right, the white dot next to f/2 indicates f/2.8. If there is no white dot for a click stop between the f/numbers, the click stop indicates the respective f/number shown below. Also, certain lenses have no intermediate click stop at both ends of the aperture scale due to a lack of space.
Using the Infrared Index 18 15 8 ft 10 3 2 m 22 16 8 50 16 11 8 5.6 4 2.8 2 1.4 A 22 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 camthe MZ-S, MZ-60, and eras since these cameras use infrared light to detect film transport operations. FA lens-Body.indd 18 22 16 8 15 8 ft 10 3 2 1 m 50 16 11 8 5.6 4 2.8 2 1.
19 Zoom Lens Infrared Index With a zoom lens, the focusing correction amount for infrared film shooting 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. FA lens-Body.
20 Lens Hood The lens hood can be round, square, or built-in. Using a lens hood is recommended 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. The hood may obstruct the flash, causing darkened areas in the picture. In the case of the FA 43mm f/1.9 lens, the flash can be used with the hood attached. FA lens-Body.
21 Compatible Lens Hoods FA lens-Body.indd 21 Lens FA 35mm f/2AL FA 43mm f/1.9Limited FA 50mm f/1.4 FA J 18-35mm f/4-5.6AL FA 20-35mm f/4AL FA J 28-80mm f/3.5-5.6AL FA 28-105mm f/3.2-4.5AL (IF) FA J 75-300mm f/4.5-5.
22 Attaching a Round Lens Hood Screw-on Type Screw the hood on to the front of the lens. FA lens-Body.indd 22 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. * When not using the lens hood, you can attach it to the lens 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. FA lens-Body.indd 23 2. The square hood should be positioned 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. FA lens-Body.indd 24 Lenses with a Built-in Lens Hood FA 31mm f/1.8AL Limited FA 77mm f/1.8 Limited FA 600mm f/4ED (IF) * Extending the FA 77mm f/1.8's lens hood does not obstruct the camera's built-in flash.
25 PL Filter Window Certain hoods also have a PL filter window. This enables you to easily rotate any polarizing or circular polarizing filter attached to the lens. Lenses with a PL filter window zFA 35mm f/2AL zFA J18-35mm f/4-5.6AL FA lens-Body.indd 25 Using the PL filter window 1. Remove the PL filter window cap by sliding it downward, as shown by the arrow.
26 2. From the PL filter window, turn the polarizing or circular polarizing filter. FA lens-Body.indd 26 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.
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. Lens orientation lock screw Tripod mount The tripod mount can also be detached. For instructions, see the FA lens instruction manual. FA lens-Body.
28 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. Filter Cautions When attached to the lens, the filter becomes part of the lens optics. Therefore, handle it in the same way as the lens. Keep it clean from dust, scratches, smudges, etc.
29 Note: Using a Circular Polarizing Filter * In the case of the FA 77mm f/1.8 Limited lens, attaching certain discontinued circular polarizing filters (including the PENTAX Type-A Circular Polarizing Filter) prevents the built-in hood from being pulled out. * With an autofocus camera, use a circular polarizing filter instead of a polarizing filter. A polarizing filter affects the accuracy of the autofocus and exposure. FA lens-Body.
30 Cautions When Using Flash 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. However, with certain lenses vignetting may still occur even if there is no blinking symbol warning. It is also possible for a lens to trigger the blinking symbol warning, but still be used with no problem.
31 Compatibility with Built-in Flash FA and FA J lenses other than the following can be used with the built-in flash with no problems. Lens FA 600mm f/4ED (IF) FA J 18-35mm f/4-5.6AL FA 20-35mm f/4AL FA J 28-80mm f/3.5-5.6AL FA 28-105mm f/4-5.6 (IF) K series × { { { { series × U*2 { { { MZ series × U*3 U*5 U*7 U*9 *1 MZ-S Z series × U*4 U*6 { { × U*3 U*5 U*8 U*9 *1: Except the MZ-S. *2: Vignetting may occur if the focal length is 18mm and the subject is closer than 1 meter.
