Sigma 120-300mm f/2.8 DG OS HSM High Grade Multi-Coated, Multi-Threaded 2-Piece Lens Filter Kit (105mm) + Nwv Direct Microfiber Cleaning Cloth

What's included: 1) UV Lens Filter 2) Circular Polarizing Filter 3) Nwv Direct Microfiber Cleaning Cloth. These filters are thin, translucent pieces of optical glass that mount in front of your lens to alter the light entering your camera and, importantly, to shield the lens surface from scratches, moisture and other damage. By controlling light and reflections, filters help photographers emphasize the parts of a scene they want to highlight. The kit combines two essential filters every shooter should have. UV filter: Film and a digital CCD are more sensitive to UV light than our eyes are, which can cause hazy, bluish cast in images shot at high elevations or across long distances and over water. This UV filter cuts that UV light while also protecting the front element from wear and the elements. Circular Polarizer: reduces reflected glare that can wash out colors, improves contrast and saturation, and helps produce deep blue skies. It also removes specular reflections from non-metallic surfaces such as glass and water. Designed for 105mm thread sizes. Warranty:10 year manufacturer warranty. Made in Japan
