smc PENT AX-F A INTERCHANGEABLE LENS OPERATING MANUAL 50 15 8 10 3 2 A 22 16 11 8 5.6 4 2.8 1.4 Thank you for purchasing the smc PENTAX lens. This operating manual applies to all of the smc PENTAX FA, FA J and F lenses. ※ In this manual, smc PENTAX FA lens is referred to as FA lens.
CONTENTS ° FOR SAFE USE OF YOUR LENS ……… 1 ° PRECAUTION AND LENS MAINTENANCE …………………………… 2 ° smc PENTAX F, FA and FA J LENSES … 3 • Mount compatibility ° MOUNTING A.
WARNING • Never look at the sun through the lens or camera. Serious damage to the reti- na, or total loss of eyesight may occur. • Wrapping the strap around your neck is dangerous. Make sure that small chil- dren do not get the strap caught their neck.
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, wardrobe, drawer, vehicle, or where insect repellent or medicine is kept.
The Pentax FA lenses are primarily designed to work with the Pentax autofocus SLR (K AF - or K AF2 -mount camera), making autofocus shooting possible. When Pentax FA Zoom lenses with power zoom function are used on the Pentax K AF2 - mount camera, the camera features a Power Zoom system.
• When using FA lens with the K-mount Pentax camera having no lens information contacts, be sure to set the lens aperture ring to any f-stop other then A. If set to the "A" position, the lens will automatically be set to the minimum aperture, causing improper exposure.
1. To mount the lens on the camera body Align the red dots on the lens and camera body, and then turn the lens clockwise until it clicks into place. ※ After mounting the lens, try to turn the lens counterclockwise to make sure it is locked in place.
The lens can be mounted on the camera by aligning the finger point with the lens unlock button. • Following Limited lenses have finger point. FA31mm f/1.
To set the focus mode Slide the focus mode switch on the camera body to change the focus mode to AF (Autofocus) or MF (Manual focus). • During autofocus, do not touch the focus- ing ring of your lens or you will interfere with proper lens movement.
There is a white dot next to the maximum f- number engraved on the lens's aperture ring on many Pentax lenses. This white dot indi- cates an aperture which is darker by one stop (larger number). The illustration below shows the white dot next to f/4.
When taking infrared pictures with infrared film and either a "R2" or "02" filter, it is neces- sary to adiust the focus because the point of focus is not the same with infrared light as it is with visible light.
Square Hoods (Clip-on type) PH-SA49 FA50mm f/1.4 & f/1.7 PH-SB49 FA28mm f/2.8AL, FA Sofy28mm f/2.8 Round Hoods (screw-in-type) PH-RA49 FA50mm f/1.4 & f/1.7 RH-RA49 F & FA Zoom 35-80mm f/4-5.6 RH-RB49 FA Zoom 70-200mm f/4-5.6 F & FA Zoom 80-200mm f/4.
How to Use the Square Hood Attach the square hood to the front of the lens while pressing the knurled tabs on both sides of the hood. • Make sure to keep the top and bottom of the hood parallel with the top and bottom covers of the camera. The improper fitting will cause the vignett- ing in the picture corners.
How to Use the Built-in Hood To use a lens with a built-in hood, first extend the hood to the fullest position. The 600mm f/4 lens and 250-600mm f/5.6 zoom lenses come in screw-fixed-type. Extend these hoods while rotating them for use. See the lens instruction manual for details.
How to Use the Lens Hood with polarizing filter window 1. Remove the PL filter window cap by sliding it in the direction shown. • The hood is designed for use with a polar- izing filter or circular polarizing filter, and includes a "PL filter window" for adjusting the polarizing effect.
Notes : • Be sure that the PL filter window cap is in place if no polarizing filter or circular polar- izing filter is used. • If strong light is entering the PL filter win- dow, either attach the PL filter window cap or reverse the position of the PL filter win- dow (to top or bottom of lens).
15 FILTERS Precautions for using a polarizing filter The circular polarizing filter is thicker than an ordinary one. For this reason, using the circular polarizing filter with lenses as shown on the chart on the right may cause vignetting at the edges of picture.
16 * An FA Zoom lens without the power supply con- tacts on its mount does not have the zoom set button and auto zoom switch. ZOOM LENS 28-105 5 2 ft m A 22 16 11 8 5.
17 Pentax FA and F zoom lens incorporate two- ring system: it has separate focusing and zooming ring. You can set your desired focal length by turning the zoom ring. It may shift the focusing point slightly by changing the focal length. First, adjust zoom- ing and then adjust focus using Autofocus or focus indicator in the viewfinder.
18 Automatic lens retraction When the power zoom lens is used with K AF2 - mount cameras, the following functions work when the main switch is turned off. 1. The zoom ring automatically retracts to its shortest length. 2. The focusing ring is set to infinity( ∞ ).
19 Using the power zoom Push the zoom ring forward until the word "POWER ZOOM "appears on the ring, and move the zoom ring to right or left to change the focal length. Using the manual zoom Pull the zoom ring back to use as manual zoom ring, the word "POWER ZOOM" disap- pears.
20 Manual aperture To set the aperture of the zoom lens manual- ly, align the aperture-A index with the white- bar index. The dot on the left-hand side of the white-bar index serves as an index to align an f-stop other than "A" when shooting at a longer focal length.
21 Infrared Index of the Zoom Lens When taking infrared photographs with the zoom lens, compensation in focus is neces- sary depending upon the focal length. The distance scale of the zoom lens has infrared indexes for each focal length. Compensate for the focus according to the focal length in use (see page 9.

23 FA Macro 50mm f/2.8, FA Macro 100mm f/2.8 and FA ★ Macro 200mm f/4ED (IF) lens- es adjust focus from infinity to life-size. FA Macro 100mm f/3.5 lens adjust focus from infinity to 1/2x.
24 • When the focus range-limiter is set to "MANUAL", you can adjust focus manually. • The focus range limiter may not turn where the focus range changes between long and short distances. • Using with the K AF2 -mount cameras, manu- al focus will work with the focus-range lim- iter is set to MANUAL in autofocus mode.
25 Clamp Screw FA Macro 50mm f/2.8 and 100mm f/2.8 lens- es are equipped with a clamp screw that is used when focusing manually. With manual close-up photography using the copy stand in any situation or with the lens pointing down , if you turn the clamp screw to the ON posi- tion, rotation of the focusing ring becomes tight.
26 Tripod Mount FA ★ 200mm f/4 ED (IF) is equipped with the tripod mount. To position the camera vertical- ly or horizontally, loosen the camera position shift lock screw, turn the camera 90 ° to the right or left as desired, and tighten the lock screw firmly.
27 FA ★ 24mm f/2 lens has a focusing ring which provides autofocus and manual focus set- tings. Push the focusing ring or pull it towards you to set the autofocus or manual focus mode respectively.
28 * The illustration depicts the FA ★ 300mm f/4.5 lens : when using the FA ★ 85mm f/1.4, FA ★ 200mm f/2.8 and FA ★ Macro 200mm f/4, the operation is similar to the FA ★ 300mm f/4.5. * For FA ★ 300mmf/2.8 and FA ★ 600mm f/4 lenses, refer to their own manual, too.
29 When the lens is set to manual focus position and the focusing ring is fully rotated to the right or left to manually focus the lens, it will keep rotating as no stoppers are provided at the ∞ (infinity) or shortest distance positions. • When the focusing ring on the lens is set to the autofocus position, the focusing ring is locked.
30 Built-in FLASH With the built-in flash in popped-up position, the flash can be used if no warning indication appears when the shutter release button is pressed halfway down. However, some lens- es cause vignetting in the picture corners, even though warning indication does not appear.
