These filters offer both amateur and professional photographers HOYA's famous quality at reasonable prices. They have multiple coatings applied to both surfaces to suppress reflection and increase light transmission.
Hoya's Star 4 Cross Screen filter is designed so that a 4-point star is created from point light sources and reflections. Hoya Cross Screen filters have a surface that is etched with a fine grid pattern. Depending on the pattern, point light sources and reflections create multi-beam stars.
HOYA Pro1 Digital filters are renowned for their ability to minimise reflection at the filter surfaces which reduces flare and ghosting. The result is an average light transmission of over 97%, giving sharp contrast and well balanced colour. HOYA Pro1 Digital filters are recommended for enhancing the performance of todays multicoated lenses. The Black Almite Frame (BAF) is a black matte finish aluminium frame that reduces reflections to enhance contrast. In addition, the Black Rimmed Glass (BRG) reduces light reflection around the filter edge. Low Profile Frame (LPF) is an Ultra thin frame which helps avoid vignetting on wide-angle lenses, and the Knurled Edge Frame (KEF) aids easy attachment and removal.
