How To Maintain Camera Lenses

Learn How To Maintain Camera Lenses.

The lens is writing tool for a Photographer. It gathers the light and focuses it. The glass elements in the lens must be properly aligned and clean. Professional Lenses are tough compared to kit lenses, but that doesn’t guarantee of safety when dropped.. Lenses are full of fragile and small parts so impacts cause damage. It may not be visible soon but may get worse over time. Here are a few tips to help you keep your camera lenses clean and fit.

  • Never let water get inside the lens and therefore minimize exposure to rain, condensation, and especially around beaches where salt concentration is high in air. All of these things are hazardous to the health of your camera lens. Lenses are rather impervious to dry snow (wet snow should be avoided) because it bounces off the lens. Growth of Fungus inside the lens may deteriorate lens surface.

  • Keep the glass in your lens perfectly clean.
  • Preventing dirt from finding its way on the lens in the first place is much better than cleaning it off.
  • Always use lens caps on both the front and rear when the lens isn’t mounted on the camera body.
  • Never let an uncovered lens point straight up for any length of time so dust can’t settle on it.
  • Never touch the glass with your fingers because it leaves oil stains and smudges which are difficult to remove.
  • Every time you use a lens, always check the glass surface for any dust, smudges, or dirt. Most of the time you will find something on the glass that shouldn’t be there so always clean it off.
  • Use a soft lens cleaning brush to remove loose grit from the surface. Point the lens down while gently brushing the lens to let gravity help you remove the dirt. Carefully check the lens again to make sure all of the grit is gone. If not, repeat the process. By the way, it helps to keep the brush protected from grit too.
  • A plastic bag or it’s own case works wonders to keep the brush clean. If all of the dust and dirt is removed from the lens, go ahead and mount the lens hood and you are ready to shoot.

If you notice any smudges on the glass surfaces though, brushing the lens won’t help. You’ll need to use a micro fiber cloth to gently rub the lens beginning in the middle and work your way out to the edges of the lens. Move the cloth in a circular motion. A micro fiber cloth is specially made to clean optical glass surfaces and does a great job of it. If the smudge is still present, try using lens cleaner solution applied directly to the micro fiber cloth (not the lens surface) and rub again. This nearly always does the trick.

A word of warning, never use the micro fiber cloth first to clean the lens. Always use the brush first because the last thing you want to do is use the cloth to grind the lens with a bit of grit.

The lens has already been polished by the manufacturer, you paid good money for this service, and there is no need to “improve” on the process. You’ll likely end up scratching the lens. Don’t forget about keeping equipment that you might add to the lens spotlessly clean too. Filters and tele-converters are used in the optical path so they must be clean. Many people use UV protection (or skylight) filters to keep dirt away from the lens and to protect it. These filters should be kept clean too. The UV filter / Polarizer does add some physical protection. Any glass filter degrades the image slightly (generally unnoticeable) which normally shows up as a slight loss of sharpness and contrast.
