This mark indicates precautions that if not followed, could result in minor or medium injury to the user or damage to the equipment. CAUTION · Do not leave the lens in direct sunlight without lens caps. Sunrays passing through the lens will be intensified, and should they focus on flammable materials, fire may occur.

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. · Avoid storing the lens in areas of high temperature and humidity, where there is a risk of mildew growth. Store the lens with a desiccant in a dry cabinet, airtight container, or plastic bag. (Leaving a saturated desiccant in the storage container can cause damage to the lens. Be sure to read the instructions that came with the desiccant before use.) 2. The lens is not waterproof. When using the lens in a rain or mist, be careful not to allow it to get wet. 3. Never use any organic solvent such as thinner, alcohol, or benzine, etc. to remove dust on the lens. 4. The lens is a precise optical instrument. Be careful not to let it fall, or subject it to strong shocks or pressure. Use a cushion or similar pad to protect the lens from the vibrations of motorcycles or other vehicles, boats, etc. 5. Avoid subjecting the lens to rapid changes in temperature, otherwise condensation can 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. 6. When the lens is not attached to the camera body, attach both the supplied lens cap and lens mount cap to protect it from dust. 7. Do not leave the camera with the lens cap off attached to a tripod or other rigid camera support. The inner parts of the camera can be damaged by direct sunlight. 8. Have the lens inspected by a dealer every one or two years to maintain its high performance. 2 smc PENTAX F, FA and FA J LENSES Focusing ring Front-ring threads Distance scale 15 8 10 3 2 50 1.4 4 2.8 8 5.6 A 22 16 11 Aperture ring Depth-of-field scale Aperture-A-lock button The Pentax FA lenses are primarily designed to work with the Pentax autofocus SLR (KAFor KAF2-mount camera), making autofocus shooting possible. When Pentax FA Zoom lenses with power zoom function are used on the Pentax KAF2mount camera, the camera features a Power Zoom system. · An FA zoom lens without the power zoom contacts are shown in the illustration does not have the power zoom function. · Do not damage or dirty the power contacts. KAF2-mount KAF-mount AF coupler Lens-information contacts Power zoom contacts 3 · 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. CAUTION : · Be careful not to damage or dirty the lens information contacts and AF coupler on the mount surfaces of the camera and lens. Otherwise, failure or malfunction may result. If this occurs, wipe them gently with a clean, dry cloth. · FA J18-35mm f/4-5.6AL, FA J28-80mm f/3.5-5.6AL and FA J75-300 mm f/4.55.8AL lenses have no aperture ring to set a f-stop manually. Aperture settings are controlled automatically as if set to the auto "A" position, so accessories without an auto "A" setting cannot be used with these lenses. 4 Camera/Lens Mount Compatibility Pentax camera/lens mount compatibility chart is shown below.

In manual focus mode You can adjust focus on the subjects by turning the focusing ring manually and confirming the focus indicator in the viewfinder. · FA 28-90mm f/3.5-5.6, FA J 28-80mm f/3.5-5.6AL and FA J 75-300mm f/4.55.8AL lenses have no distance scale, adjust focus with aid of the matte field for non-auto focus camera or using focus indicator in the viewfinder for auto focus camera. 7 F-STOPS OR F-NUMBERS AND CLICK STOPS There is a white dot next to the maximum fnumber engraved on the lens's aperture ring on many Pentax lenses. This white dot indicates an aperture which is darker by one stop (larger number). The illustration below shows the white dot next to f/4.5 is f/5.6. The click stops between two engraved f/stops are equivalent to intermediate f-stops. Some lenses do not have an intermediate click fstop on the aperture ring due to limited space between the f-numbers engraved on the aperture ring. 1.4 1.2 1.7 2 2.4 2.8 3.4 4 4.8 5.6 6.7 8 9.5 11 13.5 16 19 22 26 32 38 45 8 HOW TO USE THE INFRARED INDEX 15 8 ft 10 3 2 m 22 16 8 50 22 16 8 15 8 ft 10 3 2 1 m 50 16 11 8 5.6 4 2.8 2 1.4 A 22 16 11 8 5.6 4 2.8 2 1.4 A 22 When taking infrared pictures with infrared film and either a "R2" or "02" filter, it is necessary to adiust the focus because the point of focus is not the same with infrared light as it is with visible light. As shown above, 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. · 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. · Caution : Infrared film can not be used for MZ-S, MZ-60 and * ist cameras since infrared ray is used for detecting device of film transport. It will expose infrared film in the camera. 9 LENS HOOD Make sure to use a proper size lens hood specially designed for your lens.
