FOR SAFE USE OF YOUR LENS
Although we have carefully designed these lenses for safe operation, Please be sure to follow precautions given in this page.
WARNING This mark indicates precautions that if not followed, could result in serious injury to the user.
CAUTION This mark indicates precautions that if not followed, could result in minor or medium injury to the user or damage to the equipment.
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 their neck. (A strap is supply only with some large types of lenses)
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.
1
PRECAUTION AND LENS MAINTENANCE
•Leaving the camera in the direct sunlight without covering the lens with the lens cap, may damage to the inside of the camera.
•When storing the lens in a case, attach the front and near lens caps that come supplied with the lens to protect it from dust and scratches.
•After removing the lens from the camera body, be careful not to let it roll over or fall. Be sure to place the lens with its front side down.
•Moisture can cause serious damage to optical glass elements. Storage in a damp place may cause mildew, so avoid storing
the lens in a place where temperature and
2
humidity are high. Keep you lens in as dry a place as possible.
•If you do not expect to use the lens for an extended period, store it in the case with a desiccant or it is recommended that the lens occasionally be taken out of the case and placed in a cool, dry, well-ventilated place to avoid the possibility of damage due to condensation build-up.
•Use a blower or lens brush to remove dust on the lens. If the lens becomes dirty, remove the dirty particle with a blower brush, then wipe it off with a clean cotton cloth or tissue paper moistened with lens cleaning solution.
Wipe in a spiral pattern from the center to the outside.

The Pentax FA lenses are primarily designed to work with the Pentax autofocus SLR (KAF2- or KAF2-mount camera), making autofocus shooting possible.
When Pentax FA Zoom lenses with power zoom function are used on the Pentax KAF2- mount 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.

•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.
•FAJ28-80mm f/3.5-5.6AL and FAJ75-300 mm f/4.5-5.8AL lenses have A (Auto) position only, no aperture ring to set a f-stop manually. The camera body controls aperture settings on "A" position. Camera bodies and accessories that not compatible with "A" cannot be used.

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, FAJ 28-80mm f/3.5- 5.6AL and FAJ 75-300mm f/4.5-5.8AL 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.

F-STOPS OR F-NUMBERS AND CLICK STOPS
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 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 f- stop on the aperture ring due to limited space between the f-numbers engraved on the aperture ring.

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.

•When using the FA28-70mmf/4AL lens with lens hood and filter, it may cause vignetting at edges of picture at focal length of 35mm and shorter.
•The external flash can be used with lens hood attached to lens. FA 28-70mm f/2.8AL lens with the external flash, refer to page 30 for precautions.
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.
