Camera Maintenance

as possible. As a guide, a temperature change of 10°C should be allowed to take place gradually over a period of at least 30 minutes. If this is not possible, keeping the camera in its case or bag will help somewhat in minimizing the effects of a rapid temperature change.

Extremely low temperature reduces the efficiency of the battery. Therefore, the camera should be protected against low temperature. Put the batteries into the camera right before shooting. For extremely low temperature, use new batteries.

1.Always keep the viewfinder eyepiece, lens and filter as clean as possible. To remove loose dust and dirt, first use the blower and then the brush of a lens brush. Do not try to wipe off granular dirt or dust -- its an excellent way of scratching the glass.

Smudges, such as fingerprints, should be carefully wiped away with either a lens tissue or a clean, soft cloth. Clean, plain cotton handkerchiefs that have already been washed a few times are particularly good for this. Breathing on the lens before wiping is effective; but be sure to wipe away all moisture completely. Commercial lens cleaners are also effective.

2.Never touch the mirror or the shutter curtain with your hands. (The natural acids on your skin are very damaging.) Minor dirt or spots on the mirror will not affect the clarity of your pictures.

3.Take care not to drop the camera or knock it against anything solid. Accidents or rough handling can easily damage the internal mechanism, even though extremely nothing seems to have been hurt.

4.Your camera is not waterproof. There are several places where water can get inside and do a great deal of damage. Take care to protect both body and lens from rain or splashing water. If your camera should get wet, dry it off immediately with a clean, soft cloth. Once a camera has become completely soaked, there is often nothing that can be done to make it right again. However, in such a case, take your camera as soon as possible to an authorized Asahi Pentax Service Center.

5.Where to keep your camera while you are not using it is an important point. The best storage place is cool, dry, clean and well ventilated. Because of the possible build-up of humidity, it is risky to store your camera in a cabinet or closet. Its also a good idea to keep your camera in its bag or case while you are not using it.

6.When mounting your camera on a tripod, be sure the tripod screw is no longer than 5.5mm. This is the depth of the tripod screw hole on your camera. If you use a longer screw, you will probably puncture the bottom of the hole, after which the camera will not function properly.4www.butkus.org
