ProMaster PRO63941 Protection Filter 77mm Pure Light
Thanks to a special combination of hydrophobic coatings and finely polished Schott B270 optical glass, Pure Light Protection filters have an extremely 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. 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.
Each Pure Light filter has a matte black coating applied to the very edge of its glass before being carefully set into its anodized aluminum frame. This reduces the possibility of internal reflections as light passes through.
All ProMaster Pure Light filters have the same size filter thread on the front and back. So, they are compatible with your lens cap, and they can be stacked with other, same-size filters. They also come in a terrific, eco-friendly snap case.
ProMaster Pure Light filters are crafted with care and precision in Japan.
