Get Creative With Pentax Lens Filters

Take your photography to the next level with lens filters. These circular camera lens filters available on eBay will open up new image possibilities and make photography more fun.

What types of filters should you use in your photography?

The three main types used are neutral density (ND), graduated neutral density (GND), and circular polarizing (CPL).

ND filters reduce the light entering the camera, allowing the photographer to select a slower than normal shutter speed. This allows for long exposure photography in brightly lit situations, creating beautiful shots such as flowing water or waves in motion. Graduated filters darken only a portion of the frame, for example darkening the sky to properly expose a dark foreground and a brightly lit sky. Circular polarizers are used to control reflections by polarizing the light waves entering the camera lens. By adjusting a circular polarizer, you can control the amount of glare seen on glass or smooth water surfaces. These also control the color and contrast of the sky and clouds.

What types of special effects filters are available?

There are many creative options available, including:

  • Star filters: These create artistic star points on light sources.
  • Haze filters: These make sunny days look foggy.
  • Warming or cooling filters: These change the temperature of light entering the camera.
What size lens should you buy?

The size of the lens you select is determined by the diameter of the outer ring on the lens. The dimension of this threaded ring is usually printed on the lens, for example, 67mm indicates a lens that accepts 67mm filters. The threads and sizes are standard across manufacturers so that any Pentax filter can be used with any lens of the appropriate size.

Can you use Pentax filters to protect the lens from bangs and drops?

Many photographers choose to leave a skylight or UV filter in place on their lens to protect the lens elements from damage. Filters are generally much cheaper to repair than the expensive lenses that they cover.

While this is a valid argument in most cases, it should be noted that all filters introduce false colors, lens flare, or other undesirable characteristics to the final photograph. These items are generally easily fixed on the computer during post-production, but for the highest quality photos, you may want to remove your UV filter unless it is necessary for the desired image.
