Zeikos 77mm Multi-Coated UV Filter

This filter is made from the finest solid optical glass, are ground and polished to the most practical thinness. In addition, they are heat-treated to avoid any distortion or focal shift, and each filter is subject to strict tests in order to ensure a flawless, even surface, which is essential to a quality filter and exceptional photographs.

Key Features:

• Fits 77mm lenses
• Ideal for protecting your valuable lens from scratches and dust
• UV filter absorbs ultraviolet rays to produce crisp, clear photographs
• Polarizing filter eliminates reflections from non-metallic surfaces, and increases contrast and color saturation
• FLD filter helps balance light in outdoor situations or where fluorescent lights are used

Lens filters are translucent glass placed in front of a camera lens to alter or adjust the light entering the camera and to protect the camera lens. Lens filters improve photographs by giving photographers control over light and allowing them to emphasize the features of a scene that they consider most important. This particular filter kit is a combination of the three essential filters no photographer should be without.

Filters are one of the least expensive accessories you can use to make big changes in the way your pictures look.

• UV Filters
  A UV filter is used to reduce UV rays from entering the lens and striking the film. Modern lenses often have UV protection built into them as well as digital sensors, however, UV filters are commonly used to help protect the surface of the lens from scratches, smudges, dirt and other hazards.
  
  
• Polarizing Filters
  No camera bag should be without a polarizing filter, whether you shoot digital, color film, color slide, or black and white. A polarizer is different than most filters in that it is composed of two pieces of glass, mounted independently inside a round frame so that one can be rotated relative to the other. As it is rotated, it increasingly cuts out glare and haze. With an SLR, you can actually observe this change through the viewfinder. Polarizers reduce glare from water, glass, or any non-metallic surface. You can also use a polarizer filter to darken blue skies.
  
  
• FLD Filters
  A FLD filter (fluorescent light correction) provides the perfect solution for obtaining pleasing skin tones and correct color while shooting without a flash under fluorescent lighting. This filter gives true-to-life color rendition by removing the harsh yellow-green cast ordinarily resulting from fluorescent bulbs. When shooting under natural light, a fluorescent filter dramatically increases color saturation of subjects such as sunrises and sunsets.
