This ProMaster 58mm Pure Light filter can be used to remove or control reflections, improve contrast & saturation, or darken blue skies. It also protects your valuable lens against the elements such as sand, dirt, oil, water, and even fingerprints.
Thanks to a special combination of hydrophobic coatings, finely polished SchottTM B270 optical glass, and top-of-the-line polarizing films Pure Light CPL filters have a high light transmission rating, very low light reflectivity, and are color neutral. This equates to a pure transfer of the image to your camera’s digital sensor or film while gaining the creative benefits of a circular polarizing filter. Not only do these filters offer excellent protection for your lens against sand, dirt, oil, water, and fingerprints; but they are also easy to clean. Plus, any camera’s auto focus system works perfectly with a Pure Light CPL.
