He found that lens coatings offer superior protection and that cheap UV filters can degrade image sharpness. However, he does acknowledge that UV filters can be used as splash or spray guards to protect lenses in dusty or wet environments. To address the issue of UV filters blending in with lens barrels, he created MAVEN Splash Guards with a distinctive grey color and features such as pure white optical glass, multi-resistant coating, and hydrophobic nano-coating.
